If no towers are destroyed during overtime, there is a tiebreaker, where the tower with the lowest health is destroyed. Here, the player who destroys an opposing tower wins instantaneously.
Matches last three minutes, and if both of the players/teams have an equal number of crowns (or none at all) at that point, the match continues into a two-minute overtime period. Destruction of the opponent's 'King's Tower' results in an instantaneous 'three-crown' victory. Clash Royale is a tower rush video game which puts players in games featuring two or four players (1v1 or 2v2) in which the objective is to destroy more towers than their opponent(s), with each destroyed tower being represented as a 'crown'.
