There are a number of formats used in various levels of competition in sports and games to determine an overall champion. Some of the most common are the single elimination , the best-of- series, the total points series more commonly known as on aggregate , and the round-robin tournament .
124-417: A single-elimination ("knockout") playoff pits the participants in one-game matches, with the loser being dropped from the competition. Single-elimination tournaments are often used in individual sports like tennis . In most tennis tournaments, the players are seeded against each other, and the winner of each match continues to the next round, all the way to the final. When a playoff of this type involves
248-422: A single-elimination bracket. Thirty-two teams automatically qualify for the tournament by winning their conference tournament, played during the two weeks before the tournament, and thirty-six teams qualify by receiving an at-large bid based on their performance during the season. The Selection Committee determines the at-large bids, ranks all the teams 1 to 68, and places the teams in the bracket, all of which
372-571: A No. 11 seed. Since 2012, the committee has released the No. 1 to 68 true seed list after announcing the bracket. Since 2017, the Selection Committee has released a list of the top 16 teams three weeks before Selection Sunday. This list does not guarantee any team a bid, as the Committee re-ranks all teams when starting the final selection process. The seed line of the four at-large teams competing in
496-519: A best-of- x series, as it may yield long waits for the teams winning the bye, while the teams that played in the earlier rounds would be spent when they reach the later rounds. The Big East men's basketball tournament used this format in a 16-team, five-round format. The PBA Tour uses a four-player, three-round format (sometimes a five-player, four-round format). College leagues in the Philippines use this format (four teams, three rounds) only if there
620-405: A bye through to week 3 of the tournament to play home preliminary finals, while the losers play home semi-finals in week 2. The bottom four teams play the two elimination finals, where the winners advance to week 2 away games and the losers' seasons are over. The specific advantages gained by finishing in higher positions on the league table are as follows: First and second – These teams receive
744-588: A catastrophic leg injury during the tournament. This tradition is credited to Everett Case , the coach of North Carolina State , who stood on his players' shoulders to accomplish the feat after the Wolfpack won the Southern Conference tournament in 1947. CBS, since 1987 and yearly to 2015, in the odd-numbered years since 2017, and TBS, since 2016, the even-numbered years, close out the tournament with " One Shining Moment ", performed by Luther Vandross . Just as
868-412: A competition that often uses the stepladder system. The League of Legends Pro League (LPL) uses a double stepladder for its playoffs, giving the top two teams a bye to the semifinals, the third and fourth-place teams a bye to the quarterfinals, and the fifth and sixth-placed teams a bye to the second round. The League of Legends Champions Korea (LCK) also used a stepladder bracket for the playoffs, while
992-426: A double-elimination format send only the top eight teams, or a mix of top teams plus the winners of a single-elimination qualifier tournament, to their conference tournament. The NCAA baseball and softball tournaments have used the format since its inception for regional and College World Series play. The Little League World Series adopted a new format in 2010 that involves four double-elimination brackets. In 2010,
1116-420: A draw may be settled in extra time and eventually by a penalty shootout or by replaying the fixture. Another perceived disadvantage is that most competitors are eliminated after relatively few games. Variations such as the double-elimination tournament allow competitors a single loss while remaining eligible for overall victory. However, losing one game requires the competitor to win more games in order to win
1240-495: A four-team group. In this usage, the format is referred to as "GSL", after the Global StarCraft II League . Dota 2 competitions often use a GSL or round-robin group stage to seed teams into a double-elimination bracket. Super Smash Bros. tournaments, as well as other fighting game competitions, typically use an open double-elimination bracket with no preceding group stage or qualifiers. The Mideast regional of
1364-639: A geographical district. Multiple conferences were considered part of each district, such as the Missouri Valley and the Big Seven conferences in one district and the Southern and Southeastern conferences in another, which often led to top-ranked teams being left out of the tournament. The issue came to a head in 1950 , when the NCAA suggested that third-ranked Kentucky and fifth-ranked North Carolina State compete in
SECTION 10
#17329097794461488-451: A match between the losers of the semifinal matches called third place playoffs , the winner therein placing third and the loser fourth. Many Olympic single-elimination tournaments feature the bronze medal match if they do not award bronze medals to both losing semifinalists. The FIFA World Cup has long featured the third place match (since 1934 ), though the UEFA Euro has not held one since
1612-399: A more traditional playoff system in 2021. The video game Rocket League had a competition that used the stepladder system. The Rocket League Championship Series (RLCS) Winter Split in the 2022–23 season used a Round Robin group stage where places 2 and 3 would go to round 1 of the playoffs , while first place would go to the quarterfinals. The RLCS Season 8 World Championship also used
1736-547: A playoff finals known as the final series. The Pro Kabaddi League and Indian Super League also uses a type of single elimination where the top two teams get byes into the semifinals while the other four teams play in two eliminators like this: Although the Indian Super League follows the UEFA champions league style of two legs in their semi finals. The 2007 AFC Asian Cup knockout stage: The "stepladder", named because
1860-426: A playoff game for a bid, but Kentucky refused, believing they should be given the bid as the higher-ranked team. In response, the NCAA doubled the field to 16 in 1951 , adding two additional districts and six spots for at-large teams. Conferences could still only have one team in the tournament, but multiple conferences from the same geographic district could now be included through at-large bids. This development helped
1984-494: A possible match-up with the top seed until one round later. MLS' format is identical, except that the conference quarterfinals is a best-of-three series. In some situations, a seeding restriction may be implemented; from 1975 until 1989 in the NFL , and from 1994 until 2011 in MLB there was a rule where at the conference or league semifinal, should the top seed and last seed (wild card) be from
2108-465: A pure knockout format was adopted beginning in 2013 . In the modern top-six system, the first round consists of knockout matches involving No. 3 vs No. 6 and No. 4 vs No. 5, with the No. 1 and No. 2 teams receiving a bye into the next round. After those matches, the format is identical to the Page playoff system. The A-League's former system had the top two teams participating in a two-legged match instead of
2232-437: A quarter-final from the previous year . Sometimes the remaining competitors in a single-elimination tournament will be "re-seeded" so that the highest surviving seed is made to play the lowest surviving seed in the next round, the second-highest plays the second-lowest, etc. This may be done after each round, or only at selected intervals. In American team sports, for example, the NFL employs this tactic, but MLS , NHL and
2356-483: A random factor is always present in a real-world competition, this might easily cause accusations of unfairness. Variations of the single-elimination tournament include: Other common tournament types include: NCAA Division I men%27s basketball tournament The NCAA Division I men's basketball tournament , branded as March Madness , is a single-elimination tournament played in the United States to determine
2480-709: A round-robin group stage. The Champions League and Europa League do the same, except each single-elimination round consists of a two-legged tie , with the winner determined by aggregate score . Most European domestic cups (e.g. the FA Cup in England or the DFB-Pokal in Germany) use hybrid systems with various round-robin and single-elimination stages. Major League Soccer (MLS) uses a single-elimination format for their playoffs ; since 2023 , all rounds are conducted as single games, except
2604-401: A separate location a week later, establishing the format with two final rounds of the tournament (although the name "Final Four" would not be used in branding until the 1980s). The 1953 tournament expanded to include 22 teams and added a fifth round, with ten teams receiving a bye to the regional semifinals. The number of teams would fluctuate from 22 to 25 teams over the next two decades, but
SECTION 20
#17329097794462728-572: A stepladder bracket. There were 2 groups of 6, and they were double elimination . The groups were also stepladders. 4 teams started in the Winner's Quarterfinal, while 2 teams started in the winner's semifinal. If a team won the winner's final, they went to the semifinal of the playoffs. If they got second (by losing the winner's final), or won the loser's final, they would go to the quarterfinal. See 2023 West Coast Conference men's basketball tournament * denotes overtime period A double-elimination format
2852-424: A team is not moved out of their preferred geographical region an inordinate number of times based on their placement in the previous two tournaments. To follow these rules and preferences, the committee may move a team off of their expected seed line. Thus, for example, the 40th overall ranked team, originally slated to be a No. 10 seed within a particular region, may instead be moved up to a No. 9 seed or moved down to
2976-674: Is 1 v 8, 2 v 7, 3 v 6 and 4 v 5, for example this is used for 16 seeds in the World Snooker Championship and 32 seeds in the World Darts Championship . Some tournaments stray from this, for example it is not the procedure that is followed in most tennis tournaments, where the 1 and 2 seeds are placed in separate brackets, but then the 3 and 4 seeds are assigned to their brackets randomly, and so too are seeds 5 through 8, and so on. This may result in some brackets consisting of stronger players than other brackets, and since only
3100-437: Is an undefeated team, and if there are seven teams or more participating. Otherwise for tournaments of seven or more teams where no team won all games, it uses a single-elimination two-round, four teams format. While Nippon Professional Baseball 's Climax Series has been called a "stepladder" playoff with only three participating teams (in two rounds), it functions mostly as a single-elimination tournament with three teams, and
3224-586: Is considered a "home court". For the First Four and the Final Four, the home court prohibition does not apply because only one venue hosts these rounds. The First Four is regularly hosted by the Dayton Flyers ; as such, the team competed on their home court in 2015 . Because the Final Four is hosted at indoor football stadiums, it is unlikely that a team will play on their home court in the future. The last time this
3348-533: Is first - for example, if sorting the numbers 1-4 ascending, if 4 and 3 meet in the first round, 3 and 1 will lose in the first round and 2 will lose in the second, selecting 4 as the largest number in the set, but insufficient comparisons have been performed to determine which is greater, 1 or 3. Despite this, the candidate that loses in the final round is commonly considered to have taken second place (in this case, 2). When matches are held to determine places or prizes lower than first and second, these typically include
3472-627: Is one in which a participant ceases to be eligible to win the tournament's championship upon having lost two matches. The exact schedule shape will change depending on the number of teams per bracket. In the United States, a double-elimination format is used in most NCAA and high school baseball and softball tournaments. Starting in 2010 , the Little League World Series in baseball also adopted this format. Teams are eliminated from contention after incurring two losses in each round of play. Most major collegiate baseball conferences with
3596-417: Is played over three weekends, with two rounds occurring each weekend. Before the first weekend, eight teams compete in the First Four to advance to the first round. Two games pair the lowest-ranked conference champions and two games pair the lowest-ranked at-large qualifiers. The first and second rounds are played during the first weekend, the regional semifinals and regional finals during the second weekend, and
3720-507: Is rare in English itself, with noticeable use in American debate tournaments. The round before the round of sixteen is sometimes called round of thirty-two in English. Terms for this in other languages generally translate as "sixteenth final". Earlier rounds are typically numbered counting forwards from the first round, or by the number of remaining competitors. If some competitors get a bye ,
3844-601: Is revealed publicly on the Sunday before the tournament, dubbed Selection Sunday by the media and fans. There is no reseeding during the tournament and matchups in each subsequent round are predetermined by the bracket. The tournament is divided into four regions, with each region having sixteen to eighteen teams. Regions are named after the U.S. geographic area of the city hosting each regional semifinal and regional final (the tournament's third and 4th round overall). Host cities for all regions vary from year to year. The tournament

3968-428: Is structurally the same as a six-team, three-round playoff. The KBO League 's Korean Series , on the other hand, is considered a stepladder system: the teams that finish fourth and fifth place play a best-of-three series (the fourth-place team automatically given a 1–0 series lead), meaning that the fourth-place team need to win only one game to advance while the fifth place have to win two. The winner of that round faces
4092-476: The 1975 NCAA Division I baseball tournament : Some playoff systems combine the features of single- and double-elimination tournaments. In these systems, one or more higher-ranked teams have an opportunity to skip a round of the playoffs by winning their first match. Even if they lose that match, they can still advance to the championship final. Lower-ranked teams receive no such break. These are variations of systems developed by Australian lawyer Ken McIntyre for
4216-421: The 1980 edition . Sometimes, contests are also held among the losers of the quarterfinal matches to determine fifth to eighth places. In one scenario, two "consolation semifinal" matches may be conducted, with the winners of these then facing off to determine fifth and sixth places and the losers playing for seventh and eighth; those are used often in qualifying tournaments where only the top five teams advance to
4340-450: The 1–2 match against the winner of the 3–4 match. The 2006 Tim Hortons Brier , Canada's national men's curling championship: McIntyre's first modification was an expansion to five teams. In this format, the first-round matches No. 2 v No. 3 and No. 4 v No. 5, with the No. 1 seed receiving a bye into the second round. The 4–5 match is played to eliminate one team, while the 2–3 match is played to determine which match they will play in
4464-439: The 2006 Bartercard Cup , the championship of New Zealand rugby league: McIntyre next developed two slightly different systems for six-team playoffs. In each system, the No. 1 and No. 2 seeds played to determine the specific semifinal match in which they would compete, while the other four teams played knockout matches in the first week to eliminate two teams and determine the other two semifinal participants. The semifinal in which
4588-426: The 2020 season, seven teams are seeded from each conference ( AFC and NFC ), with only the top team from each conference getting a first-round " bye ". The remaining six teams in each conference play against each other in the wild-card round . The lowest-seeded winner plays the lone "bye" team, and the other two winners play against each other in the divisional round; the winners of those games facing each other in
4712-693: The League of Legends Championship Series (LCS) and League of Legends Master Series (LMS) used it to determine the LCS and LMS third representatives at the League of Legends World Championship , which in this case was referred to as "The Gauntlet". The LCS scrapped the Gauntlet in 2020, while the LMS became the Pacific Championship Series (PCS) that year following a merger with Southeast Asia's scene. The LCK moved towards

Although MLB does have enough teams (12) in its playoff tournament where re-seeding would have made a large difference in the matchups; only the WNBA's at the minimum, which is at least four from each conference for a total of 8. The NBA's format calls for the winner of the first-round series between the first and eighth seeds (within each of
4960-780: The National Invitation Tournament . Founded by the Metropolitan Basketball Writers Association one year before the NCAA tournament, the NIT was held entirely in New York City at Madison Square Garden. Because New York was the center of the press in the United States, the NIT often received more coverage than the NCAA tournament in early years. Additionally, good teams were often excluded from the NCAA tournament because each conference could only have one bid and conference champions were even excluded because of
5084-449: The Super 8s phase, which follows a single round-robin phase involving all league teams, is crowned champion and receives automatic promotion to the second-tier championship , while the next four teams contest a knockout playoff for the second promotion place. A nearly identical format, with the only difference being that the knockout stage followed a full home-and-away league season, was used by

5208-519: The 2021 women's tournament about the differing facility quality and branding, both the men's and women's tournaments were branded as "NCAA March Madness" starting in 2022 with variations of the same tournament-wide logo used by the men's tournament. Additionally, the Final Four for the men's tournament was branded as the "Men's Final Four" beginning in 2022, reflecting the "Women's Final Four" branding in use for that tournament since 1987 . The tournament consists of 68 teams competing in seven rounds of
5332-454: The 8-district system before 1950. Teams often competed in both tournaments during the first decade, with City College of New York winning both the NIT and NCAA tournament in 1950. Soon after, the NCAA banned teams from participating in both tournaments. Two major changes over the course of the early 1970s led to the NCAA becoming the preeminent post-season tournament for college basketball. First,
5456-544: The AFL adopted a modified top-eight playoff in 2000 . The National Rugby League (NRL), Australia's top rugby league competition (also with a team in New Zealand), used this system from 1999 through 2011, after which it changed to the AFL system. The current AFL finals system breaks up the eight participants into four groups of two teams, ranked by their league position after regular-season play. Each group receives an advantage over
5580-559: The Final Four has exclusively been played in large indoor football stadiums. Beginning in 2001 , the field was expanded from 64 to 65 teams, adding to the tournament what was informally known as the "play-in game" . This was in response to the creation of the Mountain West Conference during 1999. Originally, the winner of the Mountain West's tournament did not receive an automatic bid, as doing so would have eliminated one of
5704-399: The First Four games pit 16 seeds against each other. The two other games, however, pit the last at-large bids against each other. The seeding for the at-large teams will be determined by the selection committee and fluctuates based on the true seed ranking of the teams. Explaining the reasoning for this format, selection committee chairman Dan Guerrero said, "We felt if we were going to expand
5828-429: The First Four has varied each year, depending on the overall ranking of the at-large teams in the field. In the men's tournament, all sites are nominally neutral; teams are prohibited from playing tournament games on their home courts during the first, second, and regional rounds. Under NCAA rules, any court on which a team hosts more than three regular-season games (not including preseason or conference tournament games)
5952-594: The First Round and the Second Round and the First Four became the official name of the opening round. In 2016 , the NCAA introduced a new "NCAA March Madness" logo for tournament-wide branding, including fully-branded courts at each of the tournament venues. Previously, the NCAA had used the existing court or a generic NCAA court. Beginning in 2017 , the #1 overall seed picks the sites for their first and second round games and their potential regional games. Additionally,
6076-657: The MLS playoffs or Liga MX Liguilla , the A-League finals series uses one-off matches throughout, culminating in the A-League Grand Final . This format is a departure from norms in football codes in Australia; previously, the A-League used a hybrid elimination system that allowed top teams in the regular season to lose one finals match but still win the tournament. The Philippines Football League 's inaugural 2017 season also featured
6200-405: The NCAA added a rule in 1971 that banned teams who declined an invitation to the NCAA tournament from participating in other post-season tournaments. This was in response to eighth-ranked Marquette declining its invitation in 1970 and instead participating in and winning the NIT after coach Al McGuire complained about their regional placement. Since then, the NCAA tournament has clearly been
6324-470: The NCAA compete with the National Invitation Tournament for prestige. In the eight team format, the tournament was split into the East and West Regions, with champions meeting in the national championship game. The first two rounds for each region were conducted at the same site and the national championship and, from 1946 , consolation game occurred a week later. Some years, the site of the national championship

Theoretically, if a higher-ranked team always beats a lower-ranked team, the second game will be arranged No. 1 vs. No. 8, No. 2 vs. No. 7, etc.; the third will be arranged No. 1 vs. No. 4, No. 2 vs. No. 3; the fourth will be arranged No. 1 vs. No. 2. The brackets are fixed, meaning teams are not re-seeded between rounds. In association football , the World Cup uses single-elimination knockout rounds after
6572-469: The No. 5 true seed will not be paired with the No. 1 true seed. The committee ensures competitive balance among the top four seeds in each region by adding the true seed values up and comparing the values among the regions. If there is significant deviation, some teams will be moved among the regions to balance the true seed distribution. If a conference has two to four teams in the top four seeds, they will be placed in different regions. Otherwise, teams from

The loser of the championship game receives a silver-plated national runner-up trophy for second place. Since 2006, all four Final Four teams receive a bronze plated NCAA regional championship trophy; prior to 2006, only
6820-827: The Phoenix regional in 2004, the Chicago regional in 2005, and the Minneapolis regional in 2006, but reverted to the traditional geographic designations beginning in 2007 . For the 2011 tournament, the South Region was the Southeast Region and the Midwest Region the Southwest Region; both returned to their previous names in 2012. The 1996 Final Four was the last to take place in a venue built specifically for basketball. Since then,
6944-812: The QF. Single-elimination tournament A single-elimination, knockout , or sudden-death tournament is a type of elimination tournament where the loser of each match-up is immediately eliminated from the tournament. Each winner will play another in the next round, until the final match-up, whose winner becomes the tournament champion(s). Each match-up may be a single match or several, for example two-legged ties in European sports or best-of series in North American pro sports. Defeated competitors may play no further part after losing, or may participate in "consolation" or "classification" matches against other losers to determine
7068-608: The U.S. division and the International division were split into two four-team pools, with each pool conducting a double-elimination tournament to determine its winner. After the end of double-elimination play, the U.S. pool winners play one another in single games, as do the International pool winners, with the losers playing a third-place game and the winners playing a final. This was altered in 2011 so that all eight U.S. teams and all eight international teams played in one large bracket each, with each bracket's winner playing each other for

This system, also bearing the name of its promoter Percy Page, is a four-team playoff first developed for Australian rules football . It has been used in many competitions in that sport and in rugby league , but is most prominent in softball and curling (which use
7316-573: The at-large bids. As an alternative to eliminating an at-large bid, the NCAA expanded the tournament to 65 teams . The #64 and #65 seeds were seeded in a regional bracket as 16 seeds, and then played the opening round game on the Tuesday preceding the first weekend of the tournament. This game was always played at the University of Dayton Arena in Dayton, Ohio. Starting in 2004 , the selection committee revealed
7440-406: The bracket resembles a step ladder , is a variation of the single-elimination tournament; instead of the No. 1 seed facing the No. 16 seed in the first round, the bracket is constructed to give the higher seeded teams byes , where the No. 1 seed has bye up to the third (or fourth) round, playing the winner of game between the No. 8 seed and the No. 9-versus-No. 16 winner. This setup is seldom used in
7564-480: The bracket, the Committee ranks the whole field from 1 to 68; these are referred to as the true seed . The committee then divides the teams amongst the four regions, giving each a seed between No. 1 and No. 16. The same four seeds in all the regions are referred to as the seed line (i.e. the No. 6 seed line). Eight teams are doubled up and compete in the First Four . Two of the paired teams compete for No. 16 seeds, and

The third-place games were eliminated during this era, with the last regional third-place games played in 1975 and the last national third-place game played in 1981 . In 1985 , the tournament expanded to 64 teams, eliminating all byes and play-ins. For

All teams are guaranteed at least three games; the first team eliminated from each pool plays a "crossover game" that matches an eliminated U.S. team with an eliminated International team. Many esports , such as Counter-Strike and StarCraft , use a double-elimination bracket in competitions to determine the top two teams in
7936-453: The competition, seeding is often used to prevent this. Brackets are set up so that the top two seeds could not possibly meet until the final round (should both advance that far), none of the top four can meet prior to the semifinals, and so on. If no seeding is used, the tournament is called a random knockout tournament. Standard seeding pairs the highest and lowest, then second highest and second lowest and so on, for an 8 seed tournament this
8060-717: The conference championships. In all cases, the higher-seeded team plays at home. The winners of the conference championships then face each other in the Super Bowl for the league championship. Like the NFL, the Canadian Football League (CFL) also uses one-game single-elimination playoffs, and has used them almost exclusively since the 1973 season. In the CFL, six teams qualify for the playoffs, divided into two divisional brackets of three teams each. The second-place teams in each division host
8184-504: The conference quarterfinals, which is best-of-three series. Liga MX in Mexico , which splits its season into two phases , uses playoffs known as the Liguilla to determine the champions of each phase. Unlike the MLS system, all Liguilla matches are two-legged ties. Australia 's A-League introduced a six-team knockout playoff, known locally as a "finals series", in the 2012–13 season . Unlike

The only exception to a strict single-elimination format since the early 1970s was in 1986 (for that season only), when the league amended its playoff format to allow a fourth-place team in one division to qualify in place of a third-place team with a worse record. That year, when only two East Division teams qualified—compared to four Western teams—the rules mandated

They must win two finals matches to reach the grand final. Third and fourth – Like the top two teams, they receive the double-chance, and must win two finals matches to reach the grand final. However, they only get to play one finals match at home—a Semi-final if they lose their QF, or Preliminary Final if they win

As part of this expansion, the round of 64 was renamed the Second Round and the round of 32 was renamed the Third Round, with the First Four being officially the First Round. In 2016 , the rounds of 64 and 32 returned to their previous names of
8680-478: The first edition not to be held, and decided against releasing the brackets that the Selection Committee had been working on. In 2021 , the tournament was held entirely in the state of Indiana to reduce travel. This was to date the only time the tournament was conducted in one state. As a COVID-19 precaution, all participating teams were required to stay in NCAA-provided accommodations until they lost. The schedule
8804-535: The first time, all teams had to win six games to win the tournament. This expansion led to increased media coverage and popularity in American culture. Until 2001 , the First and Second Rounds occurred at two sites in each region. In 1985, the Mideast Region was renamed the Southeast Region. In 1997 , the Southeast Region became the South Region. From 2004 to 2006 , the regions were named after their host cities, e.g.
8928-450: The highest ranked teams normally get the closest sites. The possible pods by seeding are: * Vacated title not included A total of 333 teams have appeared in the NCAA tournament since 1939. Because the NCAA did not split into divisions until 1957 , some schools that have appeared in the tournament are no longer in Division I . Among Division I schools, 46 have never made
9052-443: The lower final rankings; for example, a third place playoff between losing semi-finalists. In a shootout poker tournament , there are more than two players competing at each table, and sometimes more than one progresses to the next round. Some competitions are held with a pure single-elimination tournament system. Others have many phases, with the last being a single-elimination final stage, often called playoffs . In English ,
9176-462: The major one, with conference champions and the majority of the top-ranked teams participating. Second, the NCAA allowed multiple teams per conference starting in 1975 . This was in response to several highly ranked teams being denied bids during the early 1970s. These included South Carolina in 1970, which was undefeated in conference play but lost in the ACC tournament; second-ranked USC in 1971 , which
9300-593: The men's college basketball national champion of the Division I level in the National Collegiate Athletic Association . Played mostly during March, the tournament consists of 68 teams and was first conducted in 1939 . Known for its upsets of favored teams, it has become one of the biggest annual sporting events in the US. The 68-team format was adopted in 2011 ; it had remained largely unchanged since 1985 when it expanded to 64 teams. Before then,
9424-460: The name "Page playoff system"). The Indian Premier League , Pakistan Super League in Twenty20 cricket , and NBA play-in tournament use this format as well. In this system, the first round (sometimes called the "quarterfinals") matches No. 1 against No. 2 and No. 3 against No. 4. The winner of the 1–2 match advances directly to the final. The next round, known as the semifinal, pits the loser of
9548-565: The national championship once. All tournament games are broadcast by CBS , TBS , TNT , and truTV under the program name NCAA March Madness . With a contract through 2032, Paramount Global and Warner Bros. Discovery pay $ 891 million annually for the broadcast rights. The NCAA distributes revenue to participating teams based on how far they advance, which provides significant funding for college athletics. The tournament has become part of American popular culture through bracket contests that award money and other prizes for correctly predicting
9672-490: The national semifinals and championship game during the third weekend. Regional rounds are branded as the Sweet Sixteen and Elite Eight and the third weekend is branded as the Final Four, all named after the number of teams remaining at the beginning of the round. All games, including the First Four, are scheduled so that teams will have one rest day between each game. This format has been in use since 2011, with minor changes to
9796-615: The national semifinals were rotated on a yearly basis instead of the two eastern and two western regions always playing. Seeding also began during this era, adding drama and ensuring better teams had better paths to the Final Four. In 1978 , teams were seeded in two separate pools based on their qualification method. Each region had four teams which automatically qualified ranked Q1–Q4 and four teams which received an at-large bid ranked L1–L4. In 1979 , all teams in each region were seeded 1 through 10, without regards for their qualification method. The national semifinals were moved to Saturday and
9920-399: The next round; or some method of ranking the four quarterfinal losers might be employed, in which case only one round of additional matches would be held among them, the two highest-ranked therein then playing for fifth and sixth places and the two lowest for seventh and eighth. The number of distinct ways of arranging a single-elimination tournament (as an abstract structure, prior to seeding
10044-422: The number of rounds remained the same. The double region naming was kept until 1956 , when the regions were named the East, Midwest, West, and Far West. In 1957 , the regions were named East, Mideast, Midwest, and West, which remained until 1985. Regions were paired in the national semifinals based on their geographic locations, with the two eastern regions meeting in one semifinal and two western regions meeting in
10168-414: The opportunity to face every other player/team. Also, if the competitors' performance is variable, that is, it depends on a small, varying factor in addition to the actual strength of the competitors, then not only will it become less likely that the strongest competitor actually wins the tournament, in addition the seeding done by the tournament organizers will play a major part in deciding the winner. As
10292-411: The other divisional bracket, thereby preserving the first-place byes. In both the men's and women's NCAA college basketball tournaments, there are 68 teams seeded into four brackets of 16 teams each. Prior to the first round, eight teams (4 No. 16 seeds and 4 other seeds) play a play-in game to gain entry into the "main" bracket. In the first round, the No. 1 team plays the No. 16, the No. 2 plays
10416-476: The other semifinal. Beginning in 1946 , a national third-place game was held before the championship game. Regional third-place games were played in the West from 1939 and the East from 1941 . Despite expansion in 1951 , there were still only two regions, each with a third-place game. The 1952 tournament had four regions each with a third-place game. This era of the tournament was characterized by competition with
10540-472: The other two paired teams are the last at-large teams awarded bids to the tournament and compete for a seed line in the No. 10 to No. 14 range, which varies year to year based on the true seeds of the teams overall. The top four overall seeds are placed as No. 1 seeds in each region. The regions are paired so that if all the No. 1 seeds reached the Final Four true seed No. 1 would play No. 4 and No. 2 would play No. 3. The No. 2 teams are preferably placed so that
10664-525: The other. If a small number of teams play in a single elimination tournament, sometimes a consolation bracket is included to allow the eliminated teams to play more than once. This was the format of the Little League World Series until 1992. The format is less suited to games where draws are frequent. In chess , each fixture in a single-elimination tournament must be played over multiple matches, because draws are common , and because white has an advantage over black. In association football , games ending in
10788-448: The outcomes of the most games. In 2023, Sports Illustrated reported that an estimated 60 to 100 million brackets are filled out each year. The first tournament was held in 1939 and was won by Oregon . It was the idea of Ohio State coach Harold Olsen . The National Association of Basketball Coaches operated the first tournament for the NCAA. From 1939 to 1950, the NCAA tournament consisted of eight teams, with each selected from
10912-441: The overall rankings among the #1 seeds. Based on these rankings, the regions were paired so that the #1 overall seed would play the #4 overall seed in a national semifinal if both teams made the Final Four. This was to prevent the top two teams from meeting before the finals, as was largely considered the case in 1996 when Kentucky played Massachusetts in the Final Four. Previously, regional pairings rotated yearly. In 2010 , there
11036-583: The players into the tournament) is given by the Wedderburn–Etherington numbers . Thus, for instance, there are three different arrangements for five players: However, the number of arrangements grows quickly for larger numbers of players and not all of them are commonly used. Opponents may be allocated randomly (such as in the FA Cup); however, since the "luck of the draw" may result in the highest-rated competitors being scheduled to face each other early in
11160-591: The present-day Super League in the UK and France. Many lower-level leagues in both Australian rules and rugby league still use the system. A variation of the five-team playoff system has been used by the Big Bash League since its 2019-20 seaeson . In the first round, the fourth- and fifth-ranked teams play each other and the winner goes to the next round as fourth while the loser is eliminated. Then, four-way playoffs will start (1 vs 2 and 3 vs winner 4–5 match.) As used in
11284-571: The regular season (or did not take place, in some cases). In international fencing competitions, it is common to have a group stage . Participants are divided in groups of 6–7 fencers who play a round-robin tournament, and a ranking is calculated from the consolidated group results. Single elimination is seeded from this ranking. The single-elimination format enables a relatively large number of competitors to participate. There are no "dead" matches (perhaps excluding "classification" matches), and no matches where one competitor has more to play for than
11408-406: The regular-season league table to eliminate two teams in the first week of the playoffs. The procedure is: The fates of the teams in this round depend on whether they won or lost their Qualifying Final, and on their regular-season position. The four winners and the two losers that finished highest on the regular-season table advance to later rounds, with the two other losers eliminated. It guarantees
11532-446: The round at which they enter may be named the first round , with the earlier matches called a preliminary round , qualifying round , opening round , or the play-in games . Examples of the diverse names given to concurrent rounds in various select disciplines: Notes: The knockout round of the 2002 FIFA World Cup tournament: Without any additional matches, the only position a single-elimination tournament can reliably determine
11656-514: The round in which only eight competitors remain is generally called (with or without hyphenation) the quarter-final round; this is followed by the semi-final round, in which only four are left, the two winners of which then meet in the final or championship round . The round before the quarterfinals has multiple designations. Often it is called the round of sixteen , last sixteen , or (in South Asia) pre-quarterfinals . In many other languages
11780-415: The same conference are placed to avoid a rematch before the regional finals if they have played three or more times in the season, the regional semifinals if they have played twice, or the second round if they have played once. Additionally, the committee is advised to avoid rematches from the regular season and the previous years' tournament in the First Four. Finally, the committee will attempt to ensure that
11904-399: The same division, they cannot play each other; in that case, the top seed plays the worst division champion; the second-best division champion plays the wild card team. This is due to the scheduling employed for the regular season, in which a team faces any given divisional opponent more often than any given non-divisional opponent – the tournament favors match-ups that took place fewer times in
12028-490: The schedule in 2021 due to the COVID-19 pandemic . The Selection Committee, which includes conference commissioners and university athletic directors appointed by the NCAA, determines the bracket during the week before the tournament. Since the results of several conference tournaments occurring during the same week can significantly impact the bracket, the Committee often makes several brackets for different results. To make
12152-632: The second level of France's rugby union system, Pro D2 , through the 2016–17 season. Since then, Pro D2 uses a six-team playoff with the winner earning automatic promotion to the Top 14 and the runner-up entering a playoff with the 13th-place team in Top 14 for the final place in the next season's Top 14. Some knockout tournaments include a third place playoff , a single match to decide which competitor or team will be credited with finishing in third and fourth place. The teams that compete in such third place games are usually
12276-492: The second round. In the second round, the loser of the 2–3 match plays the winner of the 4–5 match, while the winner of the 2–3 match plays the No. 1 seed. From this point forward, the tournament is identical to the Page playoff system. The SANFL is the highest level league using this system today, it has been used in the past by the VFL and several rugby league competitions, most notably the short-lived Super League of Australia and
12400-404: The selection committee began releasing the top 16 seeds three weeks before Selection Sunday as a bracket preview. Due to the COVID-19 pandemic , the NCAA cancelled the 2020 tournament. Initially, the NCAA discussed holding a shortened version with only 16 teams in the Final Four host city of Atlanta. Once the vast scale of the pandemic was understood, the NCAA cancelled the tournament, making it
12524-525: The semi-finals. The winner of the upper and lower quarter-finals join the two semi-finalists in a single-elimination bracket. This system was further refined into the top-six system used by the Championship and League 1 of European rugby league until being abandoned from the 2015 season forward. A slightly modified version of this system was used in the A-League of Australian soccer starting in 2010 before
12648-400: The single-elimination matches that the other four teams faced. It did not affect the teams' eventual playoff paths. As used in the 2010–11 A-League : McIntyre's final development expanded the concept to an eight-team playoff. This expansion meant that no team received a "second chance" after the first week of the playoffs. The original McIntyre final eight system is notable in that it uses
12772-536: The team that finished in third place. The winner then plays the second-place team in a best-of-five series, whose winner in turn plays the first-place team in a best-of-seven series for the title. The WNBA , from 2019 to 2021, used to have their playoffs done this way: the No. 5 seed plays No. 8, and No. 6 plays No. 7 in the first round. The top two seeds got double byes, and the next two seeds first-round byes. The first two rounds are single-elimination; all others are best-of-five. The video game League of Legends has
12896-425: The teams directly below it on the league table. These advantages are the so-called "double-chance", where a loss in the first week will not eliminate a team from the finals, and home ground finals. Note, however, that "home" designations are often irrelevant if a finals match involves two teams from the same state. The finals format operates as follows: The top four teams play the two qualifying finals. The winners get
13020-1007: The term for these eight matches translates to eighth-final (e.g., in these European languages: "huitième de finale" in French , "achtste finale" in Dutch, octavos de final in Spanish , Achtelfinale in German , åttondelsfinal in Swedish , ottavi di finale in Italian , oitavos-de-final in Portuguese , optimi de finală in Romanian , osmifinále in Czech , osemfinále in Slovak , and osmina finala in Serbo-Croatian ), though this term
13144-468: The top 32 players of 128 are seeded in Tennis Grand Slam tournaments, it can happen that the 33rd-best player in a 128-player field could end up playing the top seed in the first round. An example of this occurring was when World No. 33 Florian Mayer was drawn against, and defeated by, World No. 1 Novak Djokovic in the first round of the 2013 Wimbledon Championships , in what was also a rematch of
13268-630: The top four teams, it is sometimes known as the Shaughnessy playoff system , after Frank Shaughnessy , who first developed it for the International League of minor league baseball . Variations of the Shaughnessy system also exist, such as in the promotion playoffs held by League 1 of the British rugby league. The League 1 playoff does not involve the top four teams; the team that tops the table after
13392-406: The top two seeds advancement, and requires the bottom two seeds to win their qualifying final. The middle four teams' fate is determined by the performance of the other four teams. The two losing teams are eliminated, and the two winning teams progress to week 3. The two losing teams are eliminated, and the two winning teams progress to the grand final. Due to perceived weaknesses of this system,
13516-556: The tournament due to COVID-19 protocols during the 48 hours after the brackets were announced. Only one game was declared a no contest due to COVID-19, with Oregon advancing to the second round because VCU could not participate due to COVID-19 protocols. VCU was not replaced by one of the first four teams out because the COVID-19 infections started more than two days after the brackets were announced. The tournament returned to its regular format in 2022 . In response to protests from players in
13640-417: The tournament expanded to 40 teams and added a sixth round; 24 teams received byes to the second round. Eight more teams were added in 1980 with only 16 teams receiving byes, and the restriction on the number of at-large bids from a conference was removed. In 1983 , a seventh round with four play-in games was added; an additional play-in game was added in 1984 . Beginning in 1973 , the regional pairings for
13764-448: The tournament sized varied from as little as 8 to as many as 53. The field was restricted to conference champions until at-large bids were extended in 1975 and teams were not fully seeded until 1979 . In 2020 , the tournament was cancelled for the first time due to the COVID-19 pandemic ; in the subsequent season, the tournament was contested completely in the state of Indiana as a precaution. Thirty-seven different schools have won
13888-551: The tournament to date. UCLA has the most with 11 championships; their coach John Wooden has the most titles of any coach with 10. The University of Kentucky (UK) has eight championships, the University of Connecticut (UConn) and the University of North Carolina have six championships, Duke University and Indiana University have five championships, the University of Kansas (KU) has four championships, and Villanova University has three championships. Seven programs are tied with two national championships, and 23 teams have won

Key For each season starting in 1979, the 4 teams seeded No. 1 are shown with double underline , and 12 teams seeded between No. 2 and No. 4 are shown with dotted underline . Bold indicates an active current streak as of the 2024 tournament. *Kansas's 2018 appearance was vacated. As a tournament ritual,
14136-470: The tournament. In a single-elimination tournament without any seeding, awarding the second place to the loser of the final is unjustified: any of the competitors knocked out before getting to play the losing finalist might have been stronger than the actual losing finalist. In general, it is only fair to use a single-elimination tournament to determine first place. To fairly determine lower places requires some form of round-robin in which each player/team gets
14260-416: The two Eastern teams play a two-game total-points series over two weekends (the two-game total point series was used as the CFL's playoff format prior to 1973), while the four Western teams played a single-elimination playoff over the same timeframe. The CFL eventually amended this format into the present "crossover rule" in 1997 so as to allow a qualifying fourth-place team to compete as the third-place team in

14508-533: The two losing semifinalists in a particular tournament. Although these semifinalists are still in effect "eliminated" from contending for the championship, they may be competing for a bronze medal , like some tournaments in the Olympic Games . Of the big four North American sports leagues , only the National Football League (NFL) uses a single-elimination system for all rounds of its postseason. Since
14632-483: The winner of the 1–2 match competes directly determines one place in the championship final (often called a "Grand Final", especially in Australia). The other semifinal is an elimination match, with the winner advancing into a "Preliminary Final" to determine the other Grand Final place. There is also one more system. Two teams are in lower-bracket round 1, two teams are in the upper-bracket quarter-finals and two teams are in
14756-529: The winning team cuts down the nets at the end of regional championship games as well as the national championship game. Starting with the seniors, and moving down by classes, players each cut a single strand off each net; the head coach cuts the last strand connecting the net to the hoop, claiming the net itself. An exception to the head coach cutting the last strand came in 2013 , when Louisville head coach Rick Pitino gave that honor to Kevin Ware , who had suffered
14880-405: Was adjusted to provided extended time for COVID-19 evaluation before the tournament began, with the First Four occurring entirely on Thursday, the First and Second Rounds pushed one day back to a Friday-Monday window, and the Sweet Sixteen and Elite Eight pushed to a Friday-Monday window as well. Teams ranked 69–72 by the Selection Committee were put on "standby" to replace any team that withdrew from
15004-478: Was left out because their conference was represented by top-ranked UCLA ; and Maryland in 1974 , which was ranked #3 but lost the ACC tournament championship game to eventual national champion North Carolina State . To accommodate at-large bids, the tournament expanded in 1975 to include 32 teams, allowing a second team to represent a conference in addition to the conference champion, and eliminated byes. In 1979 ,

Each venue hosts two sets of four teams, referred to as "pods." To limit travel, teams are placed in pods closer to their home unless seeding rules would prevent it. Because each pod includes a top 4 seed,
15252-404: Was speculation about increasing the tournament size to as many as 128 teams. On April 1, 2010, the NCAA announced that it was looking at expanding to 96 teams for 2011 . However, three weeks later the NCAA announced a new television contract with CBS/Turner that expanded the field to 68 teams, instead of 96, starting in 2011. The First Four was created by the addition of three play-in games. Two of
15376-409: Was the same site as a regional championship and in other years a new site. With the expansion to 16 teams, the tournament retained the original format of the national semifinals being the regional finals in 1951 . For the 1952 tournament, there were four regions named East-1, East-2, West-1, West-2, all played at separate sites. The regional champions met for the national semifinals and championship at
