2 decks. Easy. 2 redeals.
Overage Solitaire uses 104 cards (2 decks). You have 6 tableau piles with 7 cards per pile and 8 foundations.
Aces are moved to the foundations as they become available.
The top cards of tableau piles and the waste pile are available to play. You may build tableau piles down in suit. One card or group of cards in the proper sequence can be moved from pile to pile. When any of the tableaus are empty you can fill the space with any card or group of cards.
You have two redeals.
Wins are rare. This solitaire variation was invented by Boris Sandberg.
