Fourfold Canfield Solitaire
4 decks. Difficult. Unlimited redeals.
This solitaire uses 208 cards (4 decks). 37 cards are counted out from the deck of 156 cards. The top card is open. This is the reserve pile. The next seven open cards are tableau piles. The next card is placed above. This will be the starter card of the foundations. The 15 other cards of the same rank will be placed next to it during play as soon as they are available.
You may build tableaus down in sequence and alternating color. Only the top card of each tableau pile and the reserve pile is available for play on the foundations. One card or group of cards in the proper sequence can be moved to another tableau pile. When one of the tableaus is empty, is automatically filled with a card from the reserve pile if possible, then by any card.
When you have made all the moves initially available, begin turning over cards from the stock pile to the waste pile. Three cards at a time are turned over from the stock. You can move cards from the stock pile to the tableau piles and to the foundations according to the rules above. You can turn over the stock pile as many times as you wish. This solitaire variation was invented by Boris Sandberg. Tip: You can move cards from the foundations back to the tableaus, if that helps you to win.
