Memory is played with an even number of cards, each with an image. Initially all cards are turned over. The goal of Memory is to find as many pairs of similar images as possible.
Taking turns, the players turn over 2 cards. When a pair is found, the player may turn over 2 more cards. The turn passes if the 2 images are different.
The game ends when all pairs are found. The player who found the most pairs wins the game.
