Concentration

Play the classic card game of concentration! This is a 2-player game. First, P1 picks two cards, then P2 picks two cards, then P1 again, then P2... this repeats until all cards have been paired off.

As for controls, you only need to move the cursor and left-click things. Oh right, you can also use ESC on your keyboard to pause the match, or to skip the card-shuffling intro that plays at the beginning of each match.
