Spider Solitaire is different from traditional Klondike Solitaire in the number of
cards used, piles available in the tableau, and the number of foundation piles needed to win the
game.
In traditional solitaire, there are 52 cards in play, seven piles in the tableau, and the player
needs to complete four foundation piles to win. In Spider Solitaire there are 104 cards in play, 10
tableau piles, and the player must complete eight foundation piles to win.
The aim of the game, however, is the same – to clear the tableau by completing ‘stacks’ of
same-suit cards, from ace to king, and moving them to the foundation pile.
