Group tournament ranking system

From Wikipedia, the free encyclopedia

In a group tournament, unlike a knockout tournament, there is no scheduled decisive final match. Instead, all the competitors are ranked by examining the results of all the matches played in the tournament. Typically, points are awarded for each match,[n 1] with competitors ranked based either on total number of points or average points per match. Alternatively, competitors may instead be ranked by winning percentage, defined as the number of wins divided by the total number of matches played.

Usually each competitor finishes with an equal number of matches, in which case rankings by total points and by average points are equivalent at the end of the tournament, though not necessarily while it is in progress. Examples with unequal numbers of matches include the 1895 County Championship in English cricket, and the U.S. National Football League prior to 1972, when tie games were excluded from the winning percentage used for regular-season standings.

Points calculation

In two-competitor games where ties are rare or impossible, competitors are typically ranked by number of wins, with ties counting half; each competitor's listings are usually ordered wins–losses(–ties). Giving a half-point for a draw in chess was introduced in 1868 by the British Chess Association; previously, drawn games in chess tournaments were replayed.[1] Where draws are more common, the award may be 2 points for a win and 1 for a draw, which is mathematically equivalent but avoids having half-points in the listings. These are usually ordered wins–draws–losses. If there are more than two competitors per match, points may be ordinal—for example, 3 for first, 2 for second, 1 for third. An extreme example of this is Formula One, where the top ten racers in each Grand Prix are given 25, 18, 15, 12, 10, 8, 6, 4, 2 and 1 respectively.

Some games may have more complex ranking criteria. For example, in rugby union, bonus points may be awarded for scoring a certain number of tries in a match, usually four, or for losing by a relatively small margin, usually 7 (the value of a converted try) or less.

Additionally in many leagues, the governing body is able to penalize a competitor who has broken the league's rules (for instance by allowing an ineligible player to play) by deducting points from that competitor's total. Sometimes this deduction may be carried over to a following season, particularly if the infraction occurs during the off-season, meaning that the competitor will start the following season with a negative points total rather than zero.

Official listings while a tournament is in progress may need to take account of competitors having played differing fractions of their schedules. Some use average points (such as the "points percentage" of the National Hockey League[2]) and others total points (such as the English Premier League, although comparisons between teams typically mention where one has "games in hand" on the other). The games behind figure used unofficially in Major League Baseball occasionally gives a different ordering from the official "winning percentage".

Association football

In association football, where draws are relatively common, many leagues give 3 points for a win and 1 for a draw in an attempt to encourage attacking play. Besides the traditional 2-1-0 points and newer 3-1-0 points systems for win-draw-loss, various other systems have been used to try to encourage attractive play. Some examples:

  • 3-2-1 as in the Greek League 1959–73;[3] or 4-2-1. Giving 1 point extra in each case for losing may be simply cosmetic, but does allow for awarding 0 points for forfeiting a match. (The FIFA standard is to count a forfeit as a 3–0 defeat.)
  • The USL W-League in 2002 gave 4-1-0 with a bonus point for scoring three goals.[4]
  • The 1981–82 League of Ireland season had 4-3-2-1-0 points for away win — home win — away draw — home draw — loss[5]
  • In China in the 1970s and 1980s, bonus points were for scoring headed goals, and for teams whose players were selected for the national squad.[6]
  • Bulgaria for three seasons 1984–87 gave no points for scoreless draws.[7]
  • France gave a bonus point for scoring 3 goals in 1973–76,[8] but stopped after rumours this encouraged match fixing. However, Michel Hidalgo has reported to the French Football Federation similar proposals to encourage attacking play.[9]
  • In the most of UEFA club competitions starting the 2004-07 cycle implemented the group stages despite UEFA Champions League first implemented it in 1992 season. In the Champions League, the group stage consists of 32 qualified teams into 8 groups of four based from the draw, but the clubs qualified for the group stage must have three points for wins, one point for the draw, head-to-head between other teams and goal differences required in order to advance to the knockout stage and however third-placed teams will be sent to the round of 32 of UEFA Cup/Europa League as well as the fourth-placed teams will be eliminated from the competition. Meanwhile for the UEFA Cup/Europa League, the system is slightly similar to the Champions League with 48 qualified teams in 12 groups of four, but both third-placed and fourth-placed teams before the introduction of the UEFA Europa Conference League will be eliminated as well.

Some leagues have used penalty shootouts after drawn games, in which case points will vary for regulation win — penalties win — penalties loss — regulation loss:


In FIBA (basketball)-sanctioned tournaments, where ties are impossible (a game goes into as many extra periods, or overtimes, as necessary to determine a winner), the following method is used:

  • Win = 2 points
  • Win (by forfeit) = 2 points
  • Loss = 1 point
  • Loss by default (team is unable to continue due to players being ejected/disqualified/injured) = 1 point
  • Loss by forfeit (team fails to appear for a scheduled game, or withdraws from the court before the end of the game) = 0 points[16]

For an example, see 2006 FIBA World Championship.

Ice Hockey

In the National Hockey League (and various minor hockey leagues), where regular season games tied after three periods go into a five-minute sudden-death overtime period and then a shootout if needed, the following method is used:

  • Win: 2 points
  • Loss in regulation time: 0 points
  • Loss in overtime or shootout: 1 point

Most European ice hockey leagues including the KHL use an alteration to the NHL method that does not encourage regulation draws by awarding more combined points than regulation decisions. This system was also used at the 2010 Winter Olympics in the preliminary round-robin games:[17]

  • Win in regulation time: 3 points
  • Win in overtime or shootout: 2 points
  • Loss in regulation time: 0 points
  • Loss in overtime or shootout: 1 point

Winning percentage

An alternative method to rank teams is winning percentage, the fraction of games or matches a team or individual has won. It is defined as wins divided by the total number of matches played (i.e. wins plus draws plus losses). A draw counts as a 12 win.

Tiebreaker criteria

When competitors are level on points, there is usually some tiebreaker criterion.

Sometimes, however, ranking ties may stand: prior to 1994, the Five Nations Championship in rugby union could result in joint champions; likewise for the British Home Championship in association football until 1978. In college football in the United States, many conferences permit joint champions (though in the top-level NCAA Division I FBS, every conference has held a single championship game since 2018). However, if ranking within the conference determines eligibility for a conference championship game or postseason bowl game, tiebreak criteria will be required to separate the potential participants. Similarly, U.S. college conferences in other sports, notably basketball, use tiebreak criteria as needed to determine seeding in postseason conference tournaments.

A tiebreaker may be a play-off, with extra matches between the tied competitors. This may be a full match or a reduced format such as a penalty shootout or speed chess. If there are more than two tied competitors in a 2-competitor game, the play-off may be a round-robin or knockout tournament, as in the 1992–93 League of Ireland.

Instead of a playoff, the original matches may provide the tie-breaker criteria:

considering only results of matches between the deadlocked competitors. If more than a single match is involved, a subtable may be used recursively for the ranking. For example, in the Super League Greece 2006-07, part of the final table was:[18]
Pos Team P W D L Pts
11 Xanthi 30 8 12 10 36
12 Iraklis 30 10 5 15 35
Apollon Kalamarias 30 9 8 13 35
Kerkira 30 8 11 11 35
15 Egaleo 30 7 7 16 28
The three teams tied on 35 points were separated by considering only matches between any two of them...:
Pos Team P W D L Pts
12 Apollon Kalamarias 4 3 0 1 9
13 Iraklis 4 1 1 2 4
Kerkira 4 1 1 2 4
...and then again for the two teams still tied:
Pos Team P W D L Pts
13 Iraklis 2 1 1 0 4
14 Kerkira 2 0 1 1 1
scoring average
the ratio of goals/points/etc. scored to those conceded.
scoring differential
the difference between goals/points/etc. scored and those conceded.
goals/points/etc. scored
irrespective of goals/points/etc.conceded.
goals/points/etc. scored away
valuing scores "on the road" above scores on one's home ground.
number of wins
in games where draws are possible
disciplinary record
fouls conceded, players sent off, etc. In 2018 FIFA World Cup Group H, Japan eliminated Senegal by receiving fewer yellow cards.
seeding or pre-tournament ranking
This may be defined to favour the higher- or lower-ranked competitor.
Koya score
the number of points achieved against all opponents who have achieved 50% or more[19]
Neustadtl score or Sonneborn–Berger score[20]
the sum of defeated opponents' scores plus half the sum of drawn opponents' scores; this method is especially common in round-robin chess tournaments; in chess or Go Swiss system tournaments (which use Swiss pairing) it is used as a secondary tie-break criterion. Ties remaining on one of these criteria may be resolved by resorting in turn to others of them. Where a group is the qualifying phase of a larger tournament, such that ties are not admissible, it may be necessary as a last resort to use drawing of lots as a tiebreaker (as was used in Group F of the 1990 FIFA World Cup to separate second and third place).
sum of defeated opponents' scores (SODOS)
suffices if draws cannot occur,[dubious ] such as in Go when komi is set to 6.5 or another half-point value.
sum of opponents' scores (SOS)
While SODOS works well, SOS fails as tie-breaker in tournaments with Swiss system pairing or that have all players play all others. But SOS makes more sense than SODOS does as tie-breaker in tournaments with McMahon pairing.[21][22]

Swiss system tournaments and variants thereof use a variety of tie-breaking criteria not found in other types of tournament which exploit features specific to the Swiss system: see tie-breaking in Swiss system tournaments. Chess and some Go tournaments use Swiss pairing.[23]
