1 deck. Easy. 2 redeals.
Aces are moved to the foundations as they become available.
You may build tableaus down in sequence and alternating color. Only the top card of each tableau pile and the reserve piles 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 it may be filled up with a card from any reserve pile, if possible, then by any card.
You have two redeals.
