This game is the extension of our classic memory game. In this game there will be a grid of cards. Each time you uncover two cards, if the objects shown in the cards match, then the cards are kept open and then you can open another pair of cards. If the cards do not match, then the cards are covered again and you need to pick a pair again. So you need to remember the positions of the objects in order to win the game. In this tricky version of memory game, the cards may switch positions. So you not only need to remember the objects behind the cards, but also need to remember the positions the cards are moved to. The fewer moves you make, the higher your score.
