A tie-break in chess is a special shortened game that allows you to determine the winner of the match if the score is tied. Usually a tie-break consists of several games of rapid chess or blitz. If these games also end in a draw, then the opponents will have to play the decisive game of armageddon. Tie breaks can also be used with other tournament systems in order for the winner to tie the points scored.

Tie-breaks can also be used in other tournaments.
