Memory, also known as Match Match, Match Up, Concentration, Pelmanism, Shinkei-suijaku, Pexeso or simply Pairs, is a card game in which all of the cards are laid face down on a surface and two cards are flipped face up over each turn. The rules given here are for a standard deck of 52 cards, which are normally laid face down in four rows of 13 cards each. In turn, each player chooses two cards and turns them face up. If they are of the same rank and color (e.g. six of hearts and six of diamonds, queen of clubs and queen of spades) then that player wins the pair and plays again. If they are not of the same rank and color, they are turned face down again and play passes to the player on the left. The game ends when the last pair has been picked up. The winner is the person with the most pairs. There may be a tie for first place.It is a particularly good game for young children, though adults may find it challenging and stimulating as well. The scheme can be employed as an educational game.If you have memory or concentration problems this game is right for you!!!
