1 deck. Easy. Unlimited redeals.
Solitaire Piquet uses one stripped deck (32 cards). 2, 3, 4, 5 and 6 of each suit is removed from the deck. You have 4 tableau piles and 4 foundations. One card is dealt to each tableau pile at the start of the game.
Aces are moved to the foundations as they become available.
You can only move a card from a tableau pile to a foundation directly above it. You cannot move cards from one tableau pile to another.
When you have made all the moves initially available, click on the stock pile to deal one card onto each tableau pile. When a foundation is finished, no cards are dealt from the stock pile to the tableau pile below this foundation. You can redeal as many times as you wish.
