The object of the game is to move all the cards to the foundations.
Foundations: Build up in same suit, from Ace to King. The top card of a foundation pile cannot be played anymore.
Tableau: Build down in alternating colors. The top card of each pile can be moved to the foundations or to the tableau. Any sequence of cards (no matter if cards are sorted down in alternating colors) may be moved to another tableau pile. An empty pile can be filled only by a King or by a sequence of cards starting with King.
