The game is a kind of memory. The difference to ordinary memory is that you have a deck of cards, four of which you hold in your hand. At the beginning of his turn, the player plays a card from his hand and then has to find the right card from the face-down cards on the table. If he succeeds, he can continue playing. At the end of his turn, he refills his hand to four. Whoever runs out of cards first is the winner.
