Sixteen foundations and sixteen tableau columns turn familiar Klondike into a sprawling board with a friendly 98% win rate, skill and luck sharing the credit.

Thomas Warfield built this four-deck take on Klondike for players who want more room to work with. It's the same game you already know, just wider: sixteen foundation piles and sixteen tableau columns instead of four and seven. You'll want a big monitor for this one, or at least a full-screen browser (press F11) to keep everything in view. It has a 98% win rate, one of the friendlier games on the site, with skill and luck sharing the credit about equally.
It plays alongside Solitaire, Double Klondike Solitaire, and Triple Klondike Solitaire, each just another step up the same ladder.

16 foundation piles: Build up from Ace to King in the same suit.
16 tableau piles: Build down by alternating color. Sequenced runs move together, also alternating color. Only a King, or a run headed by a King, may fill an empty pile. The piles are dealt in a staircase, one card in the first pile up to sixteen in the last, with only the top card of each pile face-up.
Stock: Click to deal three cards at a time to the waste. The stock can be recycled as many times as you like.
Waste: The top card of the waste is always available for play to the foundations or tableau.
There are sixteen foundation piles.
An Ace can start any empty foundation pile.
A card can be added to a foundation pile only if it's one rank higher and the same suit as the pile's current top card, so the only card that fits on a 5 of clubs is the 6 of clubs. A full pile runs from Ace to King, thirteen cards long.
The top card of any foundation pile can be moved back into play if another pile will accept it.
Sixteen tableau piles are dealt in a staircase, one card in the first pile up to sixteen in the last. Only the top card of each pile is dealt face-up; the rest are face-down.
A card can be added to a tableau pile only if it's one rank lower and the opposite color of the pile's current top card, so the only cards that fit on a 4 of spades are the 3 of hearts and 3 of diamonds.
Any tableau card not covered by another card is free to move to the foundation or another tableau pile.
Only a King, or an alternating-color run headed by a King, may fill an empty tableau pile.
A properly ordered run of alternating-color cards may be moved together from one pile to another as a single unit.
The cards left after the deal make up the stock, and there is one waste pile.
When you click the stock, three cards deal to the waste. The stock can be recycled as many times as you like; if there aren't enough cards left for a full pass, you just get whatever remains.
The top card of the waste can be played to the tableau or a foundation.
