Double Solitaire

Double Solitaire is a two-player competitive card game where players race to sort cards onto shared foundations. Each opponent builds their own tableau using a separate deck while contributing to eight central foundations. Utilizing drag-and-drop controls or hotkeys like U to undo, the objective is to clear all cards from your tableau before your opponent.

Setup

• Tableau: Two separate Klondike tableaus of 7 columns each (one for each player).
• Decks: Two distinct standard 52-card decks (one per player).
• Foundations: 8 shared central target piles in the middle.
• Stockpile: 24 remaining draw cards kept by each player.

Controls

• Move cards: Click or tap a card, then click/tap its destination
• Drag cards: Left-click and drag card to another column or center
• Auto-move card: Double-click or press Space to auto-move to foundations
• Draw card: Click your stockpile or press D
• Undo last move: Press U or click Undo
• Get a hint: Press H or click Hint
• Restart game: Press R or click Restart
• Mobile: Smooth tap and drag gestures for mobile play

Rules

1. Build your personal tableau down in alternating colors (e.g., placing a red 9 on a black 10).
2. Move only the top card of a tableau column or your active waste pile. Only a King can fill an empty column.
3. Both players race to build the same 8 shared foundation piles in the center by suit in ascending order (Ace → 2 → 3 → ... → King).
4. For turn-based play, flip cards from your stockpile to your waste pile to end your turn. For speed play, both play simultaneously.
5. Win by being the first to play all your cards to the foundations, or by having the most cards in the foundations when a deadlock occurs.

Tips

• Pay attention to your opponent's board; you can strategically hold back cards to block them from building on a shared pile.
• Prioritize revealing the face-down cards in your own longest tableau columns to unlock more moves.
• Move Aces and 2s to the shared foundations immediately to establish piles and gain a competitive foothold.
