Pairs is a concentration game.

At the beginning you can select the difficulty level. In the easiest level there are 10 cards (5 pairs) while in the most difficult level there are 84 cards (42 pairs). The object is to find pairs of cards with identical picture. In every turn you can turn over two cards (with the mouse). If the turned cards have the same picture they are removed and you have another turn. Otherwise the cards are turned back. The strength of your opponent can vary between 0 (random moves) to 9 (remembers everything). The opponents strength can be changed with the vertical cursor keys or with the digit keys.
