Each level has several monsters that you have to feed. When the monster opens its mouth, it is ready to be fed. Players choose one item card from their hand in any order to feed to the monster by scanning the QR code on the back of the card. When feeding a monster, you must give it item cards that, when mixed, produce a color similar to the color of the monster's coat. If the combination of dealt cards does not produce such a suit, the players lose that level and must start over.
