Introduction: Klondike Solitaire is perhaps the most popular solitaire card game around. It is easy to play, very relaxing, and doesn't take a lot of time per game.
Double Klondike is very similar to Klondike Deal 1, except that two decks of cards are used.
Goal: Build up all cards in sequence, from ace to king, on the eight foundation piles.
Time: About 10-12 minutes
Wins: Often
Decks: Two Decks
Layout: After shuffling, 9 tableau piles are dealt in a similar manner to Klondike Deal 1. Eight spaces are left open for foundation piles. These are in the top right part of your layout. The rest of the deck is placed in the stock pile. Here is a typical initial layout of Double Klondike Solitaire.
Play: The goal in Double Klondike Solitaire is to build each foundation pile in suit from ace to king (Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King). So, as soon as you come across an Ace, place it in any foundation pile that hasn't been started yet. Then when you uncover a 2 in the same suit, place it on the ace, then place a 3, etc.
The face-up cards on the tableau are available for play. In order to build up the foundation, you need to uncover the face-down cards in the tableau, to get them into play. You do this by moving tableau cards onto the foundation and onto other columns in the tableau. Cards on the tableau are build down in alternating colors. So, in this way, either red queen may be placed onto either black king. And, either the red six of hearts or the red six of diamonds may be placed onto either the black 7 of spades or the black 7 of clubs. These face-up cards are overlapped, so that you can see what they are. The high card is a king and the low card is an ace, so a king may not be placed on an ace in Klondike. When a face-down card becomes uncovered, and hence, becomes the top-most card in a column , that face-down card is now turned face-up and is now available for play. Cards in sequence on a column in the tableau may be moved as a unit. So a sequence consisting of a 9 of clubs, 8 of hearts, 7 of clubs, 6 of diamonds, 5 of spades, 4 of hearts, and 3 of spades may, as a single unit, be moved onto a red 10, if available.
When no more moves can be made on the tableau and foundation, turn over the top card of the stock pile (by clicking on it) to place it face-up in the waste pile. If that card can be placed onto the foundation, do so. (Tip: It is generally a good idea to build up the four foundation piles roughly evenly. If one foundation pile has more than a couple more cards in it than the other foundation piles, the foundation cards may not be available to be used in the tableau for building sequences, moving cards, and uncovering the face-down cards.) Klondike is one of the few solitaire games where cards may be taken off the foundation and placed on the tableau. (Although some say this is not a valid rule for any form of Klondike, most allow it.) The top card from the waste pile may also be placed onto a tableau column, if it follows a valid sequence. Gaps in the tableau may be filled with any available king, or a valid sequence starting with a king. Creating a gap, and getting the face-down cards uncovered and available for play is usually a good move in this Double Klondike variation of solitaire.
Continue playing in this manner. Move cards from the waste pile to the tableau and the foundation, and from the tableau to the foundation and within the tableau, and occasionally from the foundation back to the tableau, trying to uncover face-down tableau cards and move them to the foundation. When the stock pile is empty, in this variation of Klondike, you may redeal (see redeals section below).
Gaps: Gaps in the tableau in Klondike are made when all of the cards are moved out of a column of the tableau. When this happens, the gap may only be filled with a king (or a valid sequence with a king at the start of the sequence).
Redeals: In this variation of Klondike, there are an unlimited number of redeals.
