Traditional solitaire, or Klondike solitaire, is set up with seven piles of cards arranged horizontally. The first pile has one card, the second has two, the third has three, and so on. After the seven piles are dealt, the top card of each is turned over.
This initial array deals out the first 28 cards in an arrangement called a tableau. The remaining 24 cards form the draw pile. When an ace shows up, it is placed above the tableau. Each ace starts another pile, called a foundation. The game proceeds as cards within the draw pile are added to the tableau or foundations.
