Clash of Clans is a popular multiplayer online game developed by Supercell. The game is set in a medieval fantasy world where players build and manage their own virtual village, raising troops to attack other players' villages or defending against attacks from others. In the game, players can join one of two rival clans and compete with each other for resources, land, and glory. "Clash" refers to the battles between these clans, while "clans" represents the groups of players working together in the game.
