Double Freecell

Double Freecell is a two-deck solitaire card game where players sort 104 cards into foundations. Utilizing 10 columns and 8 free cells, solvers rearrange cards face-up in descending order with alternating colors. Using click-to-move controls or hotkeys like U to undo, the objective is to build eight foundations from Ace to King by suit.

Setup

• Tableau: 10 columns of cards dealt face-up (104 cards total using two decks).
• Free Cells: 8 empty temporary slots at the top left of the board.
• Foundations: 8 empty target piles at the top right of the board.

Controls

• Move cards: Click or tap a card, then click/tap its destination
• Drag cards: Left-click and drag card to another column
• Undo last move: Press U or click the Undo button
• Get a hint: Press H or click Hint
• Restart game: Press R or click Restart
• Mobile: Tap and drag cards with smooth touch controls

Rules

1. Only the top card of a tableau column or a card in a free cell is available for play.
2. Build tableau columns downward in alternating colors (e.g., placing a red Jack on a black Queen).
3. Move any single card to an empty free cell (each cell holds only one card).
4. Any card or valid sequence of cards can be placed in an empty tableau column.
5. Move cards to foundations by suit in ascending order starting with Ace up to King.

Tips

• Do not fill up all 8 free cells too early; doing so limits your ability to move and maneuver card sequences.
• Expose and move Aces to the foundations immediately to unlock building space.
• Maximize the use of empty columns—they are highly valuable for breaking down long sequences.
• Plan around rank pairs; since there are two decks, track where both identical cards are located.
