FreeCell is famous for being almost always winnable — but "almost" is the key word. Out of the standard 32,000 numbered deals, exactly 8 are provably unsolvable. Here's what you need to know about those impossible deals and how to recognize a stuck position.

Play Free FreeCell →The 8 Unsolvable FreeCell Deals
In the original Microsoft FreeCell numbering system (deals #1–32,000), exactly 8 deals have been proven impossible to win. These are:
Deal #11982 is the most famous — it's the only unsolvable deal in the first 32,000 that players regularly encounter because it appears in the standard numbered sequence. The other known unsolvable deals are scattered throughout larger numbered ranges.
For the extended deal sets used in modern FreeCell apps (millions of possible deals), the percentage of unsolvable deals remains well below 1% — FreeCell is exceptional among solitaire games for its near-universal solvability.
Why Are Some FreeCell Deals Unsolvable?
A FreeCell deal becomes unsolvable when the initial card distribution creates a configuration that no sequence of moves can resolve. The most common causes:
- Circular dependencies: Card A needs card B to move, but card B needs card A to move first
- Insufficient free cells: The cards that need to be repositioned require more temporary storage than the 4 free cells can provide, even with empty columns
- Buried low cards: Key low-rank cards (2s, 3s) buried under cards that themselves need those low cards to build down — creating an inescapable dependency loop
How to Know if You're Actually Stuck
Most times you think you're stuck, you're not — you've just missed a sequence of moves. Before giving up on a deal, run through this checklist:
- Are all 4 free cells full? If yes, can you play any free cell card to the foundation or tableau?
- Is there any card in the tableau that can move to the foundation right now?
- Can you move any tableau card to another column to unblock something?
- Have you considered moving cards back from the foundation to open up a needed sequence?
If after exhausting all possibilities no move exists, you may have hit a genuinely unsolvable configuration — or made an earlier move that led to a dead end. Using an undo feature to backtrack several moves often rescues "stuck" positions.
Is Deal #11982 Always Unsolvable?
Yes. Deal #11982 has been exhaustively analyzed by computer — every possible sequence of moves from the starting position leads to a dead end. There is no human or computer strategy that can win this specific deal. If you encounter it and can't win, you're in good company — nobody can.
Frequently Asked Questions
How many FreeCell games are unsolvable?
