Clash Royale is a real-time strategy video game developed and published by Supercell.

[7] In three years, Clash Royale made $2.5 billion in revenue according to market intelligence company Sensor Tower.

[10] In rare instances, if the King's Tower is destroyed at the same time by both players, this also results in a draw.

In Clash Royale, players were ranked by their number of trophies which are won or lost through multiplayer battles until a new system (Path of Legends) was added.

Players level up their accounts and King Towers by gaining Experience points through donating and upgrading cards.

There are twenty-three playing arenas in total (excluding the Training Camp tutorial area): Goblin Stadium, Bone Pit, Barbarian Bowl, Spell Valley, Builder's Workshop, P.E.K.K.A's Playhouse, 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, Boot Camp, Clash Fest, PANCAKES!, and Legendary Arena.

In the October 2022 update, this reset system was done away with in favor of a longer trophy road with more arenas, as well as a separate competitive gameplay mode (called Path of Legends) that would follow a similar model as the Legendary Arena.

[12] In June 2024, a limited time game mode was added introducing the Goblin Queen, replacing the central King Tower.

As goblin-themed cards are played, the Queen's ability charges up, culminating with the release of several Goblin Babies across the opponent's side of the arena.

It since now been removed, but Supercell has hinted at a potential return based on its successful performance.

These cards differentiate from other cards as a player is limited to one Champion in a deck and each Champion has a special ability that can be activated by spending additional elixir (for example, the Golden Knight's Dash ability costs 1 additional elixir).

The December 2018 update added Star Points to unlock special golden cosmetics for level 14 cards.

Players also receive Star Points when gaining experience, which can be used to give their cards an updated visual appearance, usually gold in color.

Other badges could be gained for other milestones such as number of wins in different game modes.

[19] There are four different types of trade tokens: Common, Rare, Epic and Legendary, corresponding to those card levels.

Collection Day saw players battling in a variety of game modes which would rotate every month.

[21] The game was soft-launched in Canada, Hong Kong, Australia, Sweden, Norway, Denmark, Iceland, Finland, and New Zealand for iOS platforms on January 4, 2016.

[4] Pocket Gamer's Harry Slater gave the game a score of 9/10, summing up "It's an incredible amount of rewarding fun, it's nail-biting at times, and there's content here that will keep you busy for weeks if not months.

The finalists in 2018 consisted of Nova Esports (China), KingZone Dragon-X (Asia), Vivo Keyd (Latin America), Team Queso (Europe), Immortals (North America), and Ponos Sports from Japan.

Ponos achieved second in Asia and qualified for the World Finals due to Japan's host status.

The top two teams from the seeding tournament received a bye and automatically qualified for the semifinals.

[citation needed] The second edition saw Team Liquid defeat SK Gaming by 1 HP in the semifinals, widely regarded as the best Clash Royale match.

[32][33] In 2024, Supercell held Superfest, an event encompassing the beforementioned tournaments with the addition of the Brawl Stars World Finals.

[53] The 2017 Crown Championship in London, top 16 players in the world competed for a $400,000 prize pool.

[55] [56] Clash Royale was part of an esport demonstration event during the 2018 Asian Games held in Indonesia.
