Castile

Game Objective:

The primary goal in Castile Solitaire is to build all four foundation piles from Ace up to King in the same suit, using a standard 52-card deck.

Setup & Layout:

• Deck: Use a standard 52-card deck.
• Tableau: Deal 10 tableau piles with 5 cards each, all face up.
• Reserve Cells: Place the remaining 2 cards into two separate reserve cells above the tableau, also face up.
• Foundations: Leave room for four foundation piles, which will be built up in suit from Ace to King as the game progresses.

Key Play Areas:

• Tableau: 10 piles where cards are built up or down by suit.
• Reserve Cells: 2 cells, each holding a single card that is available for play.
• Foundations: 4 piles, one for each suit, built from Ace to King.

Castile Solitaire Rules:

• Card Movement: Only one card may be moved at a time.
• Available Cards: The top card of each tableau pile and each card in a reserve cell are available for play.
• Building on Foundations: Foundations are built up by suit, starting with Ace and ending with King (e.g., Ace, 2, 3, …, King of Diamonds).
• Building on Tableau: Tableau piles can be built either up or down by suit (e.g., 8♠ onto 9♠ or 9♠ onto 8♠).
• Reserve Cell Rules: Each reserve cell may contain only one card. When a reserve cell is empty, it may be filled with the top card of any tableau pile.
• Empty Tableau Piles: When a tableau pile becomes empty, it may be filled with the top card of any tableau pile or a card from a reserve cell.
• No Redeal: There is no stock or redeal in this game; all cards are in play from the start.

Gameplay:

• Typical Sequence of Actions:
  • Move available Aces to start foundation piles as soon as they appear.
  • Build tableau piles up or down in suit by moving single cards.
  • Move cards from reserve cells to tableau or foundations when possible.
  • Fill empty tableau piles or reserve cells as permitted by the rules.
• Introducing New Cards: All cards are dealt face up at the start; no new cards are introduced during play.
• No Legal Moves: If no further moves are possible and not all foundations are complete, the game ends in a loss.

Winning & Losing Conditions:

• Winning: The game is won when all four foundation piles are built from Ace to King in their respective suits.
• Losing: The game is lost if you run out of legal moves before completing all foundation piles.

Special Rules & Edge Cases:

• Filling Empty Spaces:
  • Reserve Cells: May be filled with the top card from any tableau pile when empty.
  • Tableau Piles: May be filled with the top card from any tableau pile or a card from a reserve cell when empty.
• Sequence Movement: Only single cards may be moved at a time. Some digital implementations may allow moving partial or full sequences if enough empty tableau and reserve cells exist, as a shortcut for manual moves.
• No Stock/Draw Pile: All cards are in play from the beginning; there is no draw pile or redeal.

Definitions:

• Tableau: The main area of play where cards are arranged in piles and built up or down by suit.
• Foundation: The target piles built up from Ace to King in suit.
• Reserve Cell: A holding area for a single card, available for play.
