Sixes and Sevens

Game Objective:

The primary goal in Sixes and Sevens Solitaire is to move all 104 cards (using two standard 52-card decks) to the foundation piles by building sequences of cards by suit: Sixes foundations must be built down to Ace, and Sevens foundations must be built up to King.

Setup & Layout:

• Deck: Two standard 52-card decks (total 104 cards).
• Foundations:
• Sixes Foundations: Eight piles, each starting with a Six of each suit (all eight Sixes are removed from the decks and placed face-up as the starting cards for these piles).
• Sevens Foundations: Eight piles, each starting with a Seven of each suit (all eight Sevens are removed from the decks and placed face-up as the starting cards for these piles).
• Tableau:
• Nine tableau piles, each with one card dealt face-up.
• Stock:
• The remaining cards are placed face-down as the stock pile.
• Waste:
• The waste pile starts empty. The top card of the stock is turned face-up to form the waste when needed.

Key Play Areas Defined:

• Foundations: Sixes and Sevens piles where sequences are built.
• Tableau: Nine piles with one face-up card each; only the top card is available for play.
• Stock: Face-down pile supplying new cards.
• Waste: Face-up pile receiving cards from the stock; only the top card is available for play.

Sixes and Sevens Solitaire Rules:

• Building on Foundations:
• Sixes Foundations: Build down by suit, from Six to Ace (e.g., 6♠, 5♠, 4♠, …, A♠).
• Sevens Foundations: Build up by suit, from Seven to King (e.g., 7♠, 8♠, 9♠, …, K♠).
• Tableau Restrictions:
• No building within tableau piles; only the top card is available for movement.
• Only one card per tableau pile at any time.
• Moving Cards:
• Cards can be moved from tableau or waste to the appropriate foundation if they fit the sequence and suit requirement.
• Any single card may be moved to an empty tableau pile.
• Stock and Waste:
• Stock deals one card face-up to the waste pile when needed.
• No redeals; once the stock is depleted, no more cards are available.
• The top card of the waste is available for play to foundations or tableau.

Gameplay:

• Turn Sequence:
• Move eligible cards from tableau or waste to the foundations according to building rules.
• When a tableau pile becomes empty, fill it with the top card of the waste. If the waste is empty, fill with the top card of the stock.
• If no moves are available, deal one card from the stock to the waste pile.
• Introducing New Cards:
• Cards enter play from the stock to the waste, and then may be moved to tableau or foundations.
• No Redeals:
• Only a single pass through the stock is permitted. Once all stock cards have been dealt, no further cards can be introduced.
• When Stuck:
• If no legal moves remain and the stock is depleted, the game ends in a loss.

Winning & Losing Conditions:

• Win Condition:
• All cards are successfully built onto the foundations: Sixes foundations are completed down to Ace, and Sevens foundations are completed up to King for all suits.
• Lose Condition:
• The game is lost if the stock is depleted and no further legal moves can be made to advance cards onto the foundations.

Special Rules & Edge Cases:

• Filling Empty Tableau Piles:
• An empty tableau pile must be filled immediately with the top card of the waste. If the waste is empty, fill with the top card of the stock.
• Tableau Limit:
• Only one card may occupy a tableau pile at any time; sequences cannot be built in the tableau.
• Waste Management:
• The waste pile only receives cards from the stock; once empty, it remains so until a new card is dealt from the stock.
• No Redeals:
• There is only one pass through the stock; once all cards have been dealt, the stock cannot be replenished.
• Card Movement Restrictions:
• Only the top cards of tableau and waste are available for play to the foundations or to fill empty tableau piles.

Summary of Unique Features:

• Uses two decks (104 cards), with 16 foundation piles (eight Sixes, eight Sevens).
• Sixes foundations build down by suit; Sevens foundations build up by suit.
• No building in tableau; only single cards can be moved.
• Only one pass through the stock; no redeals.
• Immediate filling of empty tableau piles from waste or stock.
• Game is won by completing all foundation sequences; lost if stuck with no moves and stock depleted.
