Several tiebreaks have been attributed as the longest tiebreak in tennis. Match tie-breaks (also referred to as supertiebreakers), where a single game is used to decide a match when the score is one set all, have been in general use in doubles matches on the professional tours since the early 2000s. Although it had previously been used occasionally in tournaments affected by bad weather, from the beginning of 2019 the "10 point" match tie-break also became the official method of deciding singles qualifying matches which had reached one set all in ITF tournaments. Three years later, a rule change was adopted to every Grand Slam tournament, including the Olympics come 2024, once the deciding set is tied at 6-all.
