In "Non c'è 2... senza 3!" the tiles are randomly spread out on the table, face down. The player on turn flips one of them and then looks for another one with the same image. And what is the difference with a common memory game?!? The fact that each image is repeated 3 times and the tile you look for doesn't have to be on the table, it could be in your opponents loot! you have to remember this in order to steal it!
