Instructions
Flip all of the cards over so that the picture sides of the cards are face down. Arrange the cards into a rectangular grid. Keep the grid as uniform as possible, in order to prevent giving unintentional clues to players, which would make it easier to memorize the locations of certain cards.
Have the youngest player take the first turn. The player turns over any two cards in the grid, flipping them all the way over and laying them down with the pictures facing up. The player collects the two cards if the pictures on them are the same, otherwise the two cards are turned back over and it is the next player's turn. A player that makes a match takes another turn, and continues to take turns until they fail to make a match.
Have the next oldest player take his turn in the same manner. Continue to take turns, youngest to oldest, until all of the matches are made.
Have each player count up her matches. The player with the most matches wins.
