In Crystal Clans, two players go to battle, each with one of six clans: the adaptable Water Clan, the peaceful Flower Clan, the relentless Skull Clan, the innumerable Blood Clan, the wise Meteor Clan, or the unyielding Stone Clan. Leading their squads across the battlefield, players compete to gain powerful crystals which hold the power to dominate their world.

The first clan to claim four crystals wins the game and fulfills their destiny to dominate the world.
