Clash Royale accounts

Clash Royale is a freemium mobile strategy video game developed and published by Supercell. In Clash Royale, players are ranked by their level, trophies, and arena. The maximum level is thirteen, obtained by getting more experience from donating or leveling up cards. There are eleven arenas (excluding training camp) in total, with each arena having a certain trophy limit. A player wins a battle by destroying more towers than the opponent, or by destroying the opponent's "King's Tower", which grants an automatic three "crown" victory. Players battle through 11 arenas (excluding Training Camp), each requiring a certain amount of trophies.
