At the 2015 World Championships, the Uneven Bars final resulted in the coronation of four different World champions. This scenario is unlikely to repeat itself, as new rules allow ties to be broken at Worlds, just as they are at the Olympic Games.
If two or more gymnasts obtain the same total score in an event final, the one with the highest execution score will prevail. If there is still a tie, the higher difficulty score becomes the determining factor. In the All-around competition, the sum of the best three (for women) or five (for men) scores will establish the final ranking.
