You have to find all pairs of cards. The difficulty, as in the classic game, is to remember where the cards are located since they are hidden after each attempt. Mechanic Memory asks you an additional memory work because the cards move after each attempt. The game provides several modes: - A classic mode in which there is no move, - "mechanic" modes : easy, medium and hard in which one, two and four card permutations are done each round. You can also play versus an adversary with the Two Players mode option.
