First shuffle all the cards and place them with their faces down in such a way that they form a quadrangle. Then each player, in turn, picks two cards. If the cards match, the player takes the pair and has another go. If the cards picked do not match, they should be put back in their original positions. The next player has a go. The player who collects the greatest number of pairs wins.
