The objective of Double Sea Towers Solitaire is to move all cards from the tableau and cells to the eight foundation piles, building each foundation up in suit from Ace to King.
Key Play Areas:
Foundations:
Each foundation pile must start with an Ace.
Foundations are built up by suit in ascending order (Ace, 2, 3, …, King).
Tableau:
Tableau columns are built down by the same suit (e.g., 7♠ on 8♠).
Only the top card of each tableau column may be moved at any time.
Any card may be moved to an empty tableau space.
Cells:
Each cell can hold only one card.
Any single card may be moved to an empty cell.
Cards in cells can be played back to the tableau or to the foundations.
Card Movement:
Only one card may be moved at a time, whether from tableau to tableau, tableau to cell, cell to tableau, or tableau/cell to foundation.
Sequences of cards cannot be moved together as a group; only individual cards are moved.
On each turn, the player may:
Move the top card of any tableau column to another tableau column (if it follows the building-down-by-suit rule).
Move the top card of any tableau column or a card from a cell to a foundation (if it follows the building-up-by-suit rule).
Move a card to an empty cell (if the cell is vacant).
Move a card from a cell back to the tableau or foundation, as allowed by the rules.
No Stock or Reserve: There is no stock or reserve pile; all cards are in play from the start.
No Redeal: Once cards are moved, there is no redeal or reshuffling.
When No Moves Are Possible: If no legal moves remain (no cards can be moved to foundations, tableau, or cells), the game is blocked and cannot be won unless a move is undone or a new strategy is found.
Note: Double Sea Towers Solitaire is distinct from the single-deck Sea Towers/Seahaven Towers variants, which typically use 10 tableau columns, 4 cells, and stricter rules for filling empty tableau spaces (often only Kings allowed). Double Sea Towers specifically uses two decks, 11 tableau columns, 9 cells, and allows any card to fill empty tableau columns.
