FreeCell Game #11982
Out of 32,000 numbered deals shipped with Microsoft FreeCell, exactly one cannot be won. Deal #11982 is the most famous hand in solitaire history — a puzzle that has defeated every human player, every algorithm, and every brute-force search ever thrown at it. It is the game that proved FreeCell is not quite perfect.
Deal #11982 is mathematically unsolvable. This is not a matter of skill or strategy. Every possible sequence of legal moves has been exhaustively tested by computer. None of them leads to a completed game. It is the only deal in the original Microsoft set with this distinction.

Why Deal #11982 Matters
FreeCell is one of the most solvable card games ever designed. Because all 52 cards are visible from the first move, there is no hidden information and no draw-pile luck. Skilled players win well over 99% of their games. That near-perfect solvability is what makes the game so satisfying — and it is exactly why deal #11982 matters.
If every deal were winnable, FreeCell would be a solved game in the trivial sense. Deal #11982 proves that it is not. Even in a game with complete information and generous mechanics, the initial card arrangement can create a position where no sequence of legal moves reaches the goal. That single exception transforms FreeCell from a puzzle with a guaranteed solution into a genuine challenge with real stakes.
For the community, #11982 became a cultural touchstone. It is the deal people mention when debating solvability. It is the benchmark for solver software. And it is the reason every FreeCell player eventually asks the question: is every FreeCell game winnable?
The History of Deal #11982
Microsoft FreeCell debuted as part of the Win32 SDK in 1991 and became a standard inclusion in Windows starting with Windows 95. The game shipped with 32,000 numbered deals, each generated by a simple linear congruential random number generator seeded with the deal number. Players could pick any number between 1 and 32,000 and always get the same layout — a feature that turned FreeCell into a shared puzzle.
As the internet grew in the mid-1990s, FreeCell enthusiasts began systematically working through every deal. Online communities tracked which numbers had been solved and which remained open. One by one the holdouts fell — until only deal #11982 remained. No one could crack it.
The question shifted from "can a human solve it?" to "can any computer solve it?" Researchers wrote solvers that explored the full game tree, testing every legal move sequence from the starting position. The result was conclusive: deal #11982 has no solution. Every branch of the search tree terminates in a dead end. The proof was not a conjecture or a statistical estimate — it was an exhaustive enumeration.
The Internet FreeCell Project
The most famous effort was the "Internet FreeCell Project," a distributed collaboration where players reported results for each deal number. By the late 1990s, the project had confirmed solutions for 31,999 of the 32,000 deals. Only #11982 stood alone. When solver programs later confirmed the result algorithmically, the deal's status shifted from "unsolved" to "unsolvable."
Can You Play Deal #11982?
Yes — and you should. Knowing a deal is unsolvable does not remove the value of playing it. In fact, deal #11982 is one of the most instructive positions in FreeCell because it forces you to confront what "impossible" actually looks like at the board level.
Most players who try it report the same experience: the deal does not feel obviously broken. You can make moves. You can build partial sequences. You can clear a card or two to the foundations. But every promising line eventually hits a wall. The board tightens. Free cells fill. Columns lock. And then you realize there is nowhere left to go.
That experience is valuable because it sharpens your instinct for the difference between a genuinely dead position and a hard but solvable one. After playing #11982, difficult deals feel different. You start to recognize the subtle signs of a board that still has life in it.

Other Unsolvable FreeCell Deals
Deal #11982 is the only unsolvable game in the original Microsoft set of 32,000, but it is not the only unsolvable FreeCell deal that exists. When researchers extended the same exhaustive analysis to the first one million deal numbers, they found a small handful of additional impossible positions.
The confirmed unsolvable deals in the extended million-deal range are:
Eight unsolvable deals out of one million gives an insolvability rate of roughly 0.0008%. Put another way, if you play a random FreeCell deal, there is about a one in 125,000 chance it literally cannot be won. Those are extraordinary odds — and they explain why FreeCell feels so different from games like Klondike, where roughly 20% of deals are unwinnable regardless of play.
What the unsolvable deals share
There is no single obvious visual pattern that marks an unsolvable deal. They do not all look the same. What they share is a structural property: no matter how you sequence your moves, you cannot create enough space to unbury the cards that need to reach the foundations. The blockage is deep and systemic, not just a surface-level tangle.
