Three points for a win

Three points for a win is a standard used in many sports leagues and group tournaments, especially in association football, in which three (rather than two) points are awarded to the team winning a match, with no points awarded to the losing team. If the game is drawn, each team receives one point. The system places additional value on wins with respect to draws such that teams with a higher number of wins may rank higher in tables than teams with a lower number of wins but more draws.

Many leagues and competitions originally awarded two points for a win and one point for a draw, before switching to the three points for a win system. The change is significant in league tables, where teams typically play 30-40 games per season. Teams that win roughly 50% of their games are the most affected by the point system.

"Three points for a win" is supposed to encourage more attacking play than "two points for a win", as teams will not settle for a draw if the prospect of gaining two extra points (by playing for a late winning goal) outweighs the prospect of losing one point by conceding a late goal to lose the match. A second rationale is that it may prevent collusion amongst teams needing only a draw to advance in a tournament or avoid relegation. A commentator has stated that it has resulted in more "positive, attacking play". However, critics suggest teams with a one-goal lead late in a match become more negative to defend lead. The average number of goals per match in Turkey's top football division has risen significantly since the change to three points for a win.

The system was proposed for the English Football League by Jimmy Hill. It was introduced in England in 1981, but did not attract much use elsewhere until it was used in the 1994 World Cup finals. In 1995, FIFA formally adopted the system, and it subsequently became standard in international tournaments, as well as most national football leagues.

This lists association football leagues where the standard is three points for a win in regulation time, one point for a draw, zero for a defeat. The year given is when the relevant season started.

The United States used this rule only from 2000, but had not used the 2-points rule before.

Some leagues have used shootout tiebreakers after drawn matches. Major League Soccer (1996–2000) used three points for a win, one point for a shootout win, no points for a shootout loss, none for a loss. The Norwegian First Division (in 1987) and the Campeonato Brasileiro Série A and its lower divisions (in 1988) used three points for a win, two points for a shootout win, one point for a shootout loss, none for a loss. The same system will be adopted in the group stages of the 2016–17 EFL Trophy and 2016–17 Scottish League Cup (in both cases, no extra time will be played). The Iraqi Premier League has used two different variants of this system. The first was in the 1988–89 season, where three points were awarded for a win by two or more goals (after normal or extra time), two points were awarded for a one-goal win (after normal or extra time), one point was awarded for a penalty shootout win and zero points were awarded for penalty shootout defeats or defeats after normal or extra time. The second variant was used in the 1994–95 season, where three points were awarded for a one-goal or two-goal win, but four points were awarded for a win by three or more goals.
