The basis of Cat Hiding DX — with the "DX" standing for "deluxe edition" — is Cat Hiding, a memory game in which each player starts with a hand of three cards; each card has three cat pictures, such as the face, tail or paws. A 4x4 grid of matching cards of each cat picture are placed face down. The active player plays a card from her hand, then flips three cards in the grid face up. If these cards match the card from her hand, she scores it. She may then attempt to match a second card from her hand, etc. Cat Hiding DX includes components for five variant editions of the game, including a new type of target card and cat dice.
