Famous FreeCell Deals

Some FreeCell deal numbers have earned a reputation that goes far beyond the game board. They are reference points for difficulty, solvability research, and community lore. This page collects the deals worth knowing by number, explains what makes each one notable, and links you straight to the board.

Why these deals matter

Every FreeCell deal number maps to a specific card layout generated by the original Microsoft algorithm. Some of those layouts became famous because they defined the boundaries of the game: the easiest starting points, the hardest solvable puzzles, and the handful of boards that no one can beat.

Mathematically Proven

The Impossible Deals

Out of the first 1,000,000 Microsoft FreeCell deals, only 8 have been confirmed impossible through exhaustive computer analysis. No legal sequence of moves can solve them. They are not merely hard or obscure; they are mathematically proven dead ends. That means roughly 99.999% of all FreeCell deals are solvable, which is part of what makes the game so compelling.

#11982Impossible

The most famous impossible FreeCell deal. It was the first game in the original 32,000-deal Microsoft set proven to have no solution, making it a touchstone for the entire solvability debate.

#146692Impossible

One of eight confirmed impossible deals in the extended 1,000,000-deal set. Its unsolvability was verified by exhaustive computer search, confirming that the board has no legal winning path.

#186216Impossible

A confirmed impossible deal discovered during large-scale solver analysis. Like #11982, no legal sequence of moves can untangle this particular arrangement of cards.

#455889Impossible

An impossible deal in the mid-range of the million-deal set. It demonstrates that unsolvable positions are scattered unpredictably across the deal space, not clustered in any obvious pattern.

#495505Impossible

Another confirmed impossible deal verified through exhaustive search. Its position helped researchers estimate the overall solvability rate for FreeCell at roughly 99.999%.

#512118Impossible

Proven impossible through exhaustive computational analysis. Its position near the midpoint of the million-deal range adds data to the census of unsolvable FreeCell positions.

#517776Impossible

Proven impossible through exhaustive search. Like the other unsolvable deals, it traps essential low cards in configurations where no sequence of legal moves can free them.

#781948Impossible

The highest-numbered confirmed impossible deal in the standard million-deal set. It sits near the top of the range and helped complete the census of unsolvable FreeCell positions.

The full list of confirmed impossible deals

The complete set of unsolvable deals in the standard million-deal range is: #11982, #146692, #186216, #455889, #495505, #512118, #517776, #781948. Every other deal in that range has at least one known solution.

Test Your Limits

The Hardest Solvable Deals

These deals are solvable, but just barely. They represent the upper edge of FreeCell difficulty: boards where the winning line is so narrow that most players will need multiple attempts, careful free-cell conservation, and deep multi-step planning to find it. If you can solve even a few of these, you are playing at an expert level.

#169Notoriously difficult

One of the most notoriously difficult solvable deals. It buries critical low cards under conflicting color ladders, forcing players to find an extremely narrow extraction sequence to win.

#178Expert challenge

An expert-level challenge that demands precise free-cell management from the very first move. One wasted temporary slot early on can close off the only winning line.

#258Buried Aces

A deal where all four aces are buried deep in the tableau. Reaching them requires a long chain of intermediate moves that tests your ability to plan several steps ahead.

#454Tight margins

Known for its razor-thin margins. Nearly every move must serve double duty, simultaneously clearing space and positioning cards for future foundation plays.

#1689Complex extraction

Features a complex extraction puzzle where important cards are tangled in multiple columns at once. Solving it requires coordinating moves across the entire board.

#3148Deep planning needed

A deal that punishes shallow thinking. The opening looks straightforward, but only deep multi-step planning reveals the single viable path to the foundations.

#7107Advanced only

Considered an advanced-only deal by the FreeCell community. Its difficulty comes from a combination of buried aces, long mixed stacks, and very few natural sequences.

#10613Near-impossible

Often described as near-impossible, though it does have a solution. The winning line requires almost perfect play with virtually no room for wasted moves or idle free cells.
