There are fifteen playing arenas in total (excluding the Training Camp tutorial area): Goblin Stadium, Bone Pit, Barbarian Bowl, P.E.K.K.A's Playhouse, Spell Valley, Builder's Workshop, Royal Arena, Frozen Peak, Jungle Arena, Hog Mountain, Electro Valley, Spooky Town, Rascal's Hideout, Serenity Peak, and The Legendary Arena. A player wins a battle by destroying more towers than the opponent (each destroyed tower being represented as a 'crown'), or by destroying the opponent's King's Tower, resulting in an automatic "three-crown" victory (unless the King's Tower was destroyed at the same time by both players, resulting in a rare draw). Trophies are won or lost through multiplayer battles. Players level up by gaining Experience (or King Level) points through donating and upgrading cards. In Clash Royale, players are ranked by their number of trophies.
If two towers have the same health, there is a draw.
If no towers are destroyed during overtime, there is a tiebreaker, where all towers rapidly lose health, and the tower with the least health is destroyed. After three minutes, if both of the players/teams have an equal number of crowns or none at all the match continues into a 2-minute overtime period and the player who destroys an opposing tower wins instantaneously. 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 the most opposing towers, with the destruction of the "King's Tower" being an instantaneous win.
