A classic but amazingly challenging solitaire game by Games-Online-Zone.com. The goal of the game is to place all cards from the tableau to the foundation. You can remove two cards of the same rank. Turn over the top of the stock (it can be turned over only 3 times), if you don't see pair on the tableau.
