2 decks. Easy. No redeal.
Picture Patience uses 104 cards (2 decks). You have 9 reserve piles with 1 card per pile and 8 foundations. An Ace and King of each suit are moved to the foundation piles during play as they become available.
When you have made all the moves initially available, begin turning over cards from the stock pile to the waste pile. You can move cards from the waste pile to the foundations according to the rules. You win when all cards are moved to the foundations.
There is no redeal.
Wins are rare.
