Klondike is a patience game (solitaire card game). In the U.S. and Canada, Klondike is the best-known solitaire
Klondike is played with a standard 52-card deck, without Jokers. After shuffling, seven piles of cards are laid from left to right. Each pile begins with one upturned card. From left to right, each pile contains one more card than the last. The first and left-most pile contains a single upturned card, the second pile contains two cards (one downturned, one upturned), the third contains three (two downturned, one upturned), and so on, until the seventh pile which contains seven cards (six downturned, one upturned). The remaining cards form the stock, and are placed facedown at the upper left of the layout.
The first objective is to release and play into position certain cards to build up each foundation, in sequence and in suit, from the ace through the king. The ultimate objective is to build the whole pack onto the foundations, and if that can be done, the Solitaire game is won.
