The game consists of a specialized deck of 52 cards which depict various sea creatures on a food chain--plankton, shrimp, little fish, big fish, seal, shark. The higher the creature is on the food chain, the more types of creatures it can chomp. Creatures cannot chomp their own kind, nor can they eat anything higher up on the food chain. Nobody can chomp an octopus or an electric eel, which are special action cards in the game.
Chomp! is for 2-4 players and recommended for ages 6+.
