1- Advanced: if you select two cards and they don't match, then their position will be exchanged. This mechanism increases a lot the game diffucult: we have to remeber the card and the position where the OTHER card was, to know where it is now!
2- Classical game: if you select two cards that don't match, they will be covered again maintaining their original position.
