Diamonsters*

Players start with identical sets of cards, each featuring a cartoon monster and a value from one to five. In each round, a card is revealed from the deck, with some monsters being more valuable than others and capable of eating diamonds from other cards. The goal is to win rounds by playing the highest card, but cards of the same value cancel each other out. The first player to collect three cards of the same value or five cards of value five wins the game.
