The cards lie face down on the table. The players take turns turning over two cards. If the pictures match, the player keeps the pair and turns over two more straight away. If they differ, the cards are turned back and it is the opponent's turn. Remember which picture was where: the cards your opponent turns over are just as useful as your own.
The game goes on until all the pairs have been found. Whoever finds more pairs wins, and an equal number is a draw. You choose the size of the board before the game: 4 × 4, 5 × 5 or 6 × 6, with 8, 12 or 18 pairs.
