This game is played with 2 decks of cards. First, 12 tableau piles of 4 cards each are dealt. The remaining cards form the stock pile. The object of the game is to move all the cards to 8 foundation piles, where each foundation pile is built up according to suit from A to K. The tableau piles can also be stacked from K to A with cards of the same suit. Each time you can move the correctly stacked cards together as a group. Empty tableau piles can be filled with any card. The stock cards are turned over one by one into a waste pile, and the top card of a waste pile can be moved to a tableau pile or to the foundations. There is no redeal of the stock cards. The 12 tableau piles form three sides of a square, while the foundation piles form the fourth side of the square. Hence the name of the game. It is unclear whether Napoleon actually played this game. The more cards you move to the foundation piles, the higher your rank.
