Prize Chests contain a variety of Cards, as well as Tokens. Cards are used to complete the player's Collections and earn Coin rewards. Tokens can be used to spin the wheel for additional prizes.
Prize Chests are randomly awarded while spinning in machines. Higher bets will provide better Chests, and increase the likelihood of a Chest being awarded. Chests may also be given as rewards for various features and events in the game.
