In the League system, players play through nine different leagues above 5000 trophies ranging from Challenger I to Ultimate Champion.

The original Legendary Arena represented the final arena following Serenity Peak, and it consisted of 'Leagues', which were added to the game in March 2017. Each arena corresponds to a certain trophy range. There are twenty-one 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, Miner's Mine, Executioner's Kitchen, Royal Crypt, Silent Sanctuary, Dragon Spa, and Legendary Arena. King Tower levels can reach level 14, and player levels can reach level 50 these factor into the competitive match-making system. Players level up their accounts and King Towers by gaining Experience points through donating and upgrading cards. In Clash Royale, players are ranked by their number of trophies which are won or lost through multiplayer battles. In rare instances in a normal game, if the King's Tower is destroyed at the same time by both players, this also results in a rare draw. If two towers have the same health, there is a draw. 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 at that point both of the players/teams have an equal number of crowns (or none at all), the match continues into a two-minute overtime period.

Destruction of the opponent's 'King's Tower' results in an instantaneous win as an automatic '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'.
