What is Klondike Solitaire?

Klondike Solitaire is a game that can be played alone with a standard 52-card deck. The tableau consists of 28 cards arranged in seven piles of increasing size with the top card face up. The game is won by building four foundation piles from Ace to King by suit.

Klondike Solitaire is the most common name of this card game, but it has also been called Fascination or Demon Patience. The origins of this game are unknown, but it dates back to at least the 18th century. Klondike is the most popular game of solitaire, although wins are relatively rare.
