the 2006–07 season. At that time, all of its playoff rounds leading up to the final, which remained a single match through 2011–12, were changed to best-of-three series. The final changed to best-of-five starting in 2012–13. Other the seasons, Gaelic football, two-legged finals were used for five seasons of the National Football League, the last in 1988–89. The International Rules Series was also two-legged in 1998–2013 and from 2017 onward. In Canadian football, two-legged total point series were occasionally used by the Canadian Football League and their predecessor leagues in the postseason, most recently in the 1986 playoffs. In Arena football, the playoff semifinals (but not the Arena Bowl itself) are decided, as of the 2018 season, by a two-legged total points playoff. In one 2018 semifinal, the first game ended in a tie, and went to overtime. However, the winner of the second game won by a larger margin (within regulation time) and was awarded overall victory based on total aggregate points. Outside of sports, the American game shows Jeopardy!, Wheel of Fortune, and The Challengers have used the two-legged tie in the final round of tournament play at some point in their history. Tiebreaking If the aggregate score is tied after the two legs, various methods can be used to break ties. Under the away goals rule, the team who scored more away goals advances. If away goals are equal, or are not considered, then the tie may be decided by extra time and/or a penalty shootout. Replays, at the second-leg venue or a neutral venue, were formerly used in European club competitions. In the Liguilla (playoffs) of the Primera División de México, the team with the better regular-season record advances; some leagues take the two teams' record against one another into account. In the promotion playoffs in Italy's Serie B (which do not necessarily occur in a given season), two-legged ties that are level on aggregate at the end of regulation time of the second leg go to extra time (away goals are not used); if the tie remains level after extra time, the team that finished higher in the league table advances. Second leg home advantage Each team hosts one match, and there is no intended advantage to whether a team plays at home first or second. However, many managers and players believe that the team playing at home for the second leg has a slight
