Trigon Left

Game Objective:

The primary goal in Trigon Left Solitaire is to move all cards from the tableau and stock to the four foundation piles, building each foundation up by suit in ascending order from Ace to King.

Setup & Layout:

• Deck Used: Standard 52-card deck (no jokers).
• Tableau: Seven tableau piles are created:
  • Pile 1: 1 card
  • Pile 2: 2 cards
  • Pile 3: 3 cards
  • Pile 4: 4 cards
  • Pile 5: 5 cards
  • Pile 6: 6 cards
  • Pile 7: 7 cards.
• Card Orientation:
  • The top card of each tableau pile is dealt face up.
  • All other cards in each pile are dealt face down.
• Foundations: Four empty foundation piles are placed above the tableau.
• Stock: Remaining undealt cards form the stock pile.
• Waste (Garbage): Cards drawn from the stock are placed face up in a single waste pile; only the top card is available for play.

Trigon Left Solitaire Rules:

• Foundation Building:
  • Foundations build up by suit (Ace → 2 → 3 … → King).
  • Only an Ace may be placed on an empty foundation pile.
  • Only the next higher card of the same suit may be placed on a foundation pile (e.g., 8♠ on 7♠).
  • Cards cannot be removed from the foundation once placed.
• Tableau Building:
  • Tableaus build down by suit (e.g., 7♠ on 8♠).
  • Only the next lower card of the same suit may be placed on a tableau pile.
  • Sequences of cards built down by suit may be moved together as a group.
  • Only Kings may fill empty tableau spaces.
• Stock and Waste:
  • Clicking the stock deals one card face up to the waste pile.
  • The top card of the waste pile may be played to the tableau or foundation.
  • An unlimited number of passes through the stock is permitted.
• Automatic Filling (Unique to Trigon Left):
  • Empty tableau spaces are automatically filled by shifting cards leftward from adjacent piles, rather than by player choice.
  • This continues until the last column is cleared, typically late in the game.

Gameplay:

• Sequence of Actions:
  • Move available cards from tableau or waste to the foundations if legal.
  • Build tableau piles by moving cards or sequences down by suit.
  • Move sequences between tableau piles if they follow the down-by-suit rule.
  • Fill empty tableau spaces automatically by shifting leftward (distinct from standard Trigon).
  • Draw cards from the stock to the waste pile as needed.
  • Play the top waste card to tableau or foundation if possible.
• Introducing New Cards:
  • Cards are introduced into play by drawing from the stock to the waste pile.
• No Legal Moves:
  • When no further legal moves are available from tableau, waste, or stock, gameplay halts.

Winning & Losing Conditions:

• Winning Condition:
  • The game is won when all 52 cards are moved to the foundation piles, completing each foundation from Ace to King by suit.
• Losing/Unwinnable Condition:
  • The game is lost or unwinnable if no further legal moves can be made and not all cards have been moved to the foundations.

Special Rules & Edge Cases:

• Automatic Filling of Empty Tableau Spaces:
  • In Trigon Left Solitaire, empty tableau spaces are filled automatically by shifting cards leftward from adjacent tableau piles, rather than by player selection.
  • This automatic filling continues until the last tableau column is cleared.
• Moving Groups:
  • Groups of cards in descending order by suit can be moved together between tableau columns if all cards in the group are of the same suit.
• Stock Passes:
  • There is no restriction on the number of passes through the stock; players may cycle through the stock as many times as needed.
• King Placement:
  • Only Kings may fill empty tableau spaces, but in Trigon Left, this is handled automatically by the game’s leftward shift mechanism.
• Edge Case—No Moves:
  • If the tableau is blocked and the stock is exhausted, and no moves to the foundation are possible, the game ends as unwinnable.

Definitions:

• Foundation: Area where cards are built up by suit from Ace to King.
• Tableau: Seven columns where cards are arranged and built down by suit.
• Stock: Pile of undealt cards used to replenish the waste.
• Waste: Discard pile where cards from the stock are placed face up; only the top card is playable.
