Clash Royale is a mobile free-to-play multiplayer real-time strategy game developed and published by Supercell for iOS and Android devices on March 2, 2016 (after a region-restricted soft-launch on January 4, 2016).
Borrowing the setting from their previous mobile MMO strategy game, Clash of Clans, Clash Royale pits two players into a small battle arena (reminiscent of Multiplayer Online Battle Arenas) as they try to destroy each other's towers with supplies of autonomous troops and support spells while defending their own towers through defensive buildings and both troop distraction and co-ordination.
Borrowing elements from collectible card games, each player must enter an arena with an eight-card "battle deck", each card representing a unit to spawn in the arena. Players must utilize the four-card hand they are given and a regenerating "elixir pool" to place units. As players unlock new cards, usually through opening acquired chests, they can upgrade the effectiveness of their cards by collecting multiple copies of the same card and "upgrading" them (at the cost of in-game Gold). Due to its freemium nature, the game allows players to purchase Gems with actual money to upgrade their cards easier and acquire rarer cards faster.
Like Clash of Clans, the game features a built-in clan system (known simply as Clans) where up to 50 players at a time can group up to chat, donate cards, share replays, and have friendly private matches.
Each match lasts up to three minutes, which can be ended earlier if all three of a player's towers (or the player's main tower) are destroyed. The player who destroyed the most towers at the end of the match wins. If both players have an equal amount of towers at the end of the match, the game is put into a one-minute overtime where the next tower to fall determines the winner (or draws the game for both players).
At the one-minute mark, elixir starts to regenerate at double the normal speed.
