2 decks. Difficult. No redeal.
Rectangle Solitaire uses 104 cards (2 decks). You have 12 tableau piles with 3 cards in each pile and 8 foundations in the center. The next card from the stock will be the starting card of foundations. The other cards of the same rank will be placed next to it during play as soon as they become available.
When you have made all the moves initially available, begin turning over cards from the stock pile. You can move cards from stock pile to the tableaus and to the foundations according to the rules above. You win when all cards are moved to the foundations.
There is no redeal.
