🏆The Hall of Fame
The most famous FreeCell deal in history. Proven mathematically impossible to solve — no sequence of legal moves leads to a win. It was the last deal standing when the internet community solved all 32,000 Microsoft deals in the 1990s.
Often cited as one of the easiest deals in the Microsoft set. Low cards are accessible early, and the deal flows naturally toward a solution with minimal use of free cells.
The very first deal in the Microsoft FreeCell numbering system. A moderately challenging game that most experienced players can solve. It’s the deal that millions of Windows users played first.
One of the hardest solvable deals in the original set. Requires an exceptionally long solution path with careful free cell management. A genuine test of expert-level play.
The first unsolvable deal found in the extended 1,000,000 deal set. Discovered when solvers expanded beyond the original 32,000 deals. Confirmed impossible through exhaustive computer search.
The last deal in the original Microsoft FreeCell set. Solving this deal meant completing the entire original game — a feat first achieved by the collaborative internet community.
❌Deal #11982: The One That Can't Be Won
In the early days of Windows FreeCell, the game shipped with 32,000 numbered deals. Players quickly realized that almost every deal could be solved with enough patience and skill. Internet communities formed to collaboratively tackle the entire set, with players claiming specific deal ranges and reporting their results.
By the mid-1990s, all 32,000 deals had been attempted. One by one, players solved even the most difficult configurations. Eventually, only a single deal remained: #11982. No human player could find a solution, and suspicion grew that it might be mathematically impossible.
Computer solvers confirmed the suspicion. Using exhaustive search algorithms that tested every possible sequence of legal moves, multiple independent programs proved that Deal #11982 has no solution. The cards create an unavoidable circular dependency where key low-value cards are trapped beneath cards that can't be moved without accessing those same low cards.
Deal #11982 became famous in the gaming community — a testament to both the near-perfect design of FreeCell and the determination of the players who solved the other 31,999 deals.
💻The Microsoft 32,000: How FreeCell Numbering Works
Microsoft FreeCell uses a pseudorandom number generator (PRNG) to convert a deal number into a specific card arrangement. The algorithm takes the deal number as a seed, then shuffles the deck using a deterministic process. This means the same deal number always produces the same card layout.
The original Windows 3.1 FreeCell (1991) included 32,000 deals numbered 1 through 32,000. Later versions expanded this to 1,000,000 deals using the same PRNG algorithm. The numbering system became a shared language among FreeCell players — you could say "try Deal #617" and anyone running Microsoft FreeCell would get the same arrangement.
This reproducibility is what made the community's systematic solving possible. Players could verify each other's claims, and the collective project of solving all 32,000 deals became one of the earliest examples of crowdsourced computational problem-solving.
🔢The Extended Set: 1,000,000 Deals
When Microsoft expanded the deal set to 1,000,000, the FreeCell community naturally extended their solving project. Among the 968,000 new deals, computer solvers found exactly 8 more unsolvable configurations:
| Deal # | Status |
|---|---|
| #11,982 | Proven Unsolvable |
| #146,692 | Proven Unsolvable |
| #186,216 | Proven Unsolvable |
| #455,889 | Proven Unsolvable |
| #495,505 | Proven Unsolvable |
| #512,118 | Proven Unsolvable |
| #517,776 | Proven Unsolvable |
| #781,948 | Proven Unsolvable |
| #875,865 | Proven Unsolvable |
That's 9 unsolvable deals out of 1,000,000 — an unsolvability rate of 0.0009%. This aligns with the estimated rate from random sampling of approximately 1 in 78,000 deals. The mathematical reasons for this extraordinary solvability lie in FreeCell's design principles.

❓Frequently Asked Questions
What is FreeCell Deal #11982?
Deal #11982 is the most famous FreeCell game number in history. It’s the only deal out of the original 32,000 Microsoft FreeCell games that has been proven mathematically impossible to solve. No sequence of legal moves can get all 52 cards onto the foundations. It was the last deal standing after the internet FreeCell community systematically solved all 32,000 deals in the mid-1990s, and its impossibility was confirmed by exhaustive computer search.
What is the easiest FreeCell deal number?
Several deals in the Microsoft set are considered exceptionally easy, but Deal #617 is often cited as one of the easiest. It can be solved in under 50 moves with straightforward play. Deals where aces and low cards start near the tops of columns tend to be the easiest because foundation building can begin immediately. The site’s deal explorer lets you browse and try specific deal numbers.
How many of the 32,000 Microsoft FreeCell deals are unsolvable?
Exactly one: Deal #11982. The other 31,999 deals have all been solved by a combination of human players and computer solvers. When the set was later extended to 1,000,000 deals, only 8 additional unsolvable deals were found (#146692, #186216, #455889, #495505, #512118, #517776, #781948, #875865), confirming FreeCell’s extraordinary solvability rate of approximately 99.999%.
Can I play specific FreeCell deal numbers on this site?
Yes. PlayFreeCellOnline.com supports numbered deals — you can enter any game number to play that specific deal. Use the deal explorer to browse notable deals, or enter a number directly to challenge a specific arrangement. Every numbered deal generates the same card layout every time, so you can retry, compare strategies, or compete with friends on the same deal.
Are FreeCell deal numbers the same across different versions?
The original Microsoft FreeCell deal numbering system (deals 1–32,000 and later 1–1,000,000) uses a specific pseudorandom number generator (PRNG) algorithm. Our site implements the same algorithm for deals in that range, so Deal #11982 here is the same impossible deal as in Windows FreeCell. However, other FreeCell implementations may use different PRNG algorithms, so the same number might produce a different card layout on a different site.
What are the hardest solvable FreeCell deals?
Among the original 32,000 Microsoft deals, some of the hardest solvable deals include #169, #178, #258, #454, #617 (ironically also one of the easiest by some metrics), and #1941. These deals require the most moves to solve and have the fewest possible solution paths. Computer solvers classify difficulty by the number of backtracks needed to find a solution — hard deals require extensive search even for AI.
