These are the complete rules of Klondike Solitaire, written as a reference. If you want to learn by playing, the beginner walkthrough is a better start. To play now, open the game on the home page.
Klondike uses one 52-card deck with no jokers. Twenty-eight cards are dealt into seven tableau columns of 1 to 7 cards, with only the top card of each face up. The remaining 24 cards form the stock. There are four foundations, which start empty. The goal is to move all 52 cards to the foundations, each built in one suit from Ace to King.
The draw mode is the main rule people choose before a game. It decides how many stock cards you can reach on each pass. Each has its own page: Turn 1 and Turn 3.
This site keeps no score and allows unlimited passes through the stock. Windows Solitaire offered two scoring systems.
FreeCell deals the whole deck face up into eight columns and has no stock. Four free cells each hold one card. Any card can go into an empty column, and the number of cards you can move at once depends on how many cells and columns are empty. Nearly every deal can be won. Here FreeCell uses the Microsoft deal numbers, and #11982 is the one that cannot be solved.
Spider Solitaire uses two decks in ten columns. Columns are built down regardless of suit, but only a run in a single suit can move together. A full run from King to Ace in one suit leaves the table. Instead of a waste pile, each deal from the stock puts one card on every column. It is played with 1, 2 or 4 suits.
Pyramid Solitaire builds nothing. Twenty-eight cards are dealt face up in a pyramid of seven rows, and you remove uncovered cards in pairs that add up to 13 (a king goes alone). The stock turns one card at a time and can be gone through three times. The game is won when the pyramid is cleared.
TriPeaks Solitaire also builds nothing. Twenty-eight cards form three peaks with only the bottom row face up, and you play them one at a time onto a single waste pile, each one rank above or below the last, in any suit; King and Ace connect. The stock turns one card at a time and is gone through once. The game is won when all three peaks are cleared.
Once the rules are clear, the strategy guide shows how to use them, the Klondike page covers the history and the odds, and the daily deal is the same game for everyone.
