A new Demon King has been crowned. The players are summoners competing for his approval by summoning demons and hiring human followers to strengthen the king's army and conquer the human realm. Players use a combination of resources to pay for either demon or human cards. These cards are used to produce more resources to obtain more powerful minions and to attack human cities on the board in return for gold and the approval of the Demon King. The game lasts for six rounds. At the end of the sixth round, the player with the most victory points (a combination of approval points and gold) is the winner. The game also includes special rules for solo play.
