Klondike Solitaire, often simply called Solitaire or Patience, is a classic card game that is typically played on computers or mobile devices. In this game, the aim is to arrange a standard deck of cards into four separate stacks, referred to as "foundations", in an order that is sorted by suit and ascends from Ace to King. At the beginning of the game, there is a tableau consisting of seven piles of cards. Each successive pile contains one more card than the previous one. The top card of each pile is turned face up, while the rest are faced down.
