The most popular solitaire game, sometimes known as Klondike. The object of the game is to build up four suit piles, starting with the Ace of each suit and ending with the King. The table consists of seven stacks of cards. The rest of the cards form a deck, from which three cards are turned over at a time. Cards can be stacked on the seven upturned cards in descending order, but only cards of the opposite color can be stacked on top of each other.
