Aces are moved to the foundations as they become available.
You can build tableaus down in sequence and alternating color. Only the top card of each tableau pile is available for play on the foundations. One card or group of cards in the proper sequence can be moved from pile to pile. Empty tableau piles may be filled by a King or group of cards in proper sequence starting with King. You can move cards back from foundations to tableau piles.
When you have made all the moves initially available, click on the stock pile to deal one card onto each tableau pile.
