Rules for Sally Solitaire

Description:

A version of Double Klondike where the base card of the foundation depends on a card dealt in.

Cards:

Two standard decks
The rank of the lowest and highest card will be determined by the first card played into the foundation.

Goal:

Move all cards to the foundation.

Foundation:

Eight foundation piles.
A random card will be dealt to a foundation pile. This is the base card. Start the remaining piles with cards of same rank.
A card may be added onto a foundation pile if it is one higher than the old top card of the pile and of the same suit.Thus, the only card that could be played on a 5♥ would be a 6♥. No pile may contain more than 13 cards.
Once on the foundation, cards may not be moved back off..

Tableau:

Nine tableau piles with one card in the first pile, two cards in the second, three in the third, and so on. The top card in each pile is dealt face up, all others are face down.
A card may be added onto a tableau pile if it is one lower than the old top card of the pile and of the opposite color.Thus, the cards that could be played on 7♠ would be 6♥ or 6♦.
Cards on the tableau that are not under another card are available for play onto the foundation or any other tableau pile.
Empty spaces in the tableau may be filled by high cards only.
Groups of cards in sequence down may be moved from one tableau column to another if the cards are alternately red and black.

Stock and Waste:

The remaining cards form the stock and there is one waste pile.
Each time you click on the stock, three cards will be dealt from the stock to the waste. Unlimited passes through the stock are permitted. At the end of any pass where there are not enough cards left in the deck just the remaining cards are dealt. The waste will be flipped over to become a new stock before the next deal.
The top card of the waste is available for play to the tableau or the foundation.
