2 decks. Difficult. 2 redeals.
Aces are moved to the Foundations as they become available.
The top cards of tableau piles are available to play. You may build tableau piles down in sequence and alternating color. One card at a time can be moved from pile to pile. When any tableaus are empty you can fill the space with any card.
When you have made all the moves initially available, click on the empty stock pile to restack the cards. During restacking all the remaining cards are first gathered together and then dealt out into 8 tableau piles.
You have two redeals.
The rules state that you can move only one card at a time. But as a shortcut, BVS Solitaire will allow you to move a full or partial build if there are enough empty tableau piles, because you would have been able to get the same result by temporarily moving the extra cards into the empty tableaus.
