A recursive memory game

I made a small logic game/puzzle called Recursi. It consists of independent “memory” games with two pairs of cards each. These games are nested recursively, behind each game there is a card of the game at a higher level. If you find two pairs, you get to flip the card at a higher level behind the current game. Sounds like fun? :) Go ahead and try it. Recursi, a fractal memory game.
