The Cat in the Hat and his friends are playing hide and seek, and players need to use their memory skills to find and match up various creatures. The game begins with 22 circle tiles placed face down on the tabletop, which have memorable Dr. Seuss characters on the reverse sides. After the tiles are set up, three cards are flopped from the top of the deck, and a player turns over two tiles in an attempt to match a card and score the tile for points. The game ends when all the characters are found, and the player with the highest score wins.
