Klondike Solitaire is probably the most popular version of Solitaire. It's also known as Fascination and Demon Patience.
Klondike is a patience game (solitaire card game). In the U.S. and Canada, Klondike is the best-known solitaire card game, to the point that most use of the term "solitaire", in the absence of additional qualifiers specifying which game, is typically referring to Klondike. The game rose to fame in the late 19th century, being named "Klondike" after the Canadian region where a gold rush happened. It is rumored that the game was either created or popularized by the prospectors in Klondike.
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 four foundations (light rectangles in the upper right of the figure) are built up by suit from Ace (low in this game) to King, and the tableau piles can be built down by alternate colors. Every face-up card in a partial pile, or a complete pile, can be moved, as a unit, to another talon pile on the basis of their highest card. Any empty piles can be filled with a King, or a pile of cards with a King. The aim of the game is to build up four stacks of cards starting with Ace and ending with King, all of the same suit, on one of the four foundations, at which time the player would have won. There are different ways of dealing the remainder of the deck from the stock to the talon, here are a few:
