Pair-O is a card game in which all of the cards are laid face down and two cards are flipped face up over each turn. The object of the game is to turn over pairs of matching cards within the allowed time. For each pair you match right, you get a time bonus of three seconds. Pair-O is an especially good game for young children, though adults may find it challenging and stimulating as well.Features:* Sound* Eye candy graphics* Time limit* Score ranking* Share and rank your score on FacebookThe same game is also available on Facebook apps:http://apps.facebook.com/pairogame/
