The Game Memory Views
Concentration, also known as Memory, 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 object of the game is to turn over pairs of matching cards. Concentration can be played with any number of players or as solitaire and is an especially good game for young children, though adults may find it challenging and stimulating as well. The scheme is often used in quiz shows and can be employed as an educational game.
An ideal strategy can be developed if we assume that players have perfect memory. For the One Flip variation below, this strategy is fairly simple. Before any turn in the game, there are t cards still in play, and n cards still in play but of known value. The current player should flip over an unknown card. If this card matches one of the known cards, the match is next chosen. Less obviously, if the card does not match any known card, one of the n known cards should still be chosen to minimize the information provided to other players. The mathematics follow:
This game is a bit like Who's Missing . This time a few students or the whole class can test their memory at the same time. Tell everyone to take a good look around the classroom. Ask them to remember where objects are located in the room. Then send a few students out of the room while you change the location of various objects in the class. You could also do this while the students are at recess or lunch. When the students come back into the classroom, ask them to write down all of the things that have changed. Make sure you keep a list of all the things that you have changed!
