♠Solvability Statistics
FreeCell stands apart from nearly every other solitaire game because of one extraordinary statistic: 99.999% of all FreeCell deals are solvable. This isn't an estimate or approximation — it's been verified through exhaustive computational analysis of millions of deals.
When Microsoft shipped FreeCell with Windows, it included 32,000 numbered deals. Researchers and enthusiasts systematically solved every single one — except deal #11982, which was proven to have no valid solution through exhaustive search. You can try deal #11982 yourself to see why it's impossible.
When analysis expanded to 1 million deals, researchers found only 8 total unsolvable configurations. The 8 known unsolvable deals are:
What makes a deal unsolvable? Unsolvable deals typically feature deeply buried key cards (especially aces) combined with card distributions that make it impossible to create enough free space to uncover them. When critical cards are trapped beneath multiple same-suit sequences and all four free cells become occupied before aces can be freed, the game reaches an unwinnable state. The four free cells simply cannot provide enough temporary storage to untangle the tableau.
♥Average Game Statistics
FreeCell is a game of perfect information — every card is visible from the first deal, with no hidden deck or face-down cards. This means your win rate is a direct reflection of skill, not luck. Here's how players typically perform:
Expert players
80-90%Consistent use of supermoves, careful planning, and efficient free cell management
Intermediate players
60-75%Solid fundamentals with occasional strategic errors in complex positions
Casual players
40-60%Basic understanding of rules, learning to plan ahead and manage resources
Beginners
20-40%Still learning the game mechanics and developing pattern recognition
Average Moves to Win
Most games are won in 45-85 moves. Simple deals with accessible aces can be solved in as few as 35 moves, while complex reorganizations may require 100+ moves. Efficient play means fewer moves — expert players average closer to 50, while beginners often exceed 80.
Average Game Duration
A typical FreeCell game takes 5-15 minutes. Speed players solve easy deals under 2 minutes, while difficult deals requiring heavy analysis can take 20-30 minutes. The sweet spot for most players is 8-12 minutes per game, balancing speed with careful decision-making.
♦Difficulty Tiers
Not all FreeCell deals are created equal. While 99.999% are solvable, their difficulty varies enormously based on the initial card distribution. Researchers classify deals into tiers based on several measurable factors.
Easy Deals
- •One or more aces visible on top of columns
- •Few cards of the same suit stacked together
- •Short columns with accessible key cards
- •Natural alternating-color sequences already formed
Medium Deals
- •Standard distribution — aces buried 2-4 cards deep
- •Some same-suit blocking but manageable with free cells
- •Requires planning 5-10 moves ahead
- •One or two tricky columns that need careful unraveling
Hard Deals
- •All four aces deeply buried (5+ cards deep)
- •Multiple same-suit sequences creating chain dependencies
- •Requires near-perfect use of all four free cells
- •May need 80+ moves and extensive use of supermoves
Key difficulty factors: The number of initially available free cells (always 4 in standard FreeCell), the depth of buried aces, the number of same-suit card pairs blocking each other, and whether kings are positioned to allow efficient column management. Variants like Baker's Game (same-suit building only) are inherently harder because they restrict which cards can stack on each other.
♣Comparison with Other Solitaire Games
FreeCell's near-perfect solvability rate is exceptional among solitaire games. Here's how it compares to other popular variants, each analyzed with optimal play:
| Game | Solvability | Hidden Cards? | Skill vs Luck |
|---|---|---|---|
| FreeCell | ~99.999% | None | Pure skill |
| Spider (1 suit) | ~99% | Yes (stock) | Mostly skill |
| Klondike (draw 1) | ~79% | Yes (tableau + stock) | Mixed |
| Baker’s Game | ~75% | None | Pure skill |
| Spider (4 suits) | ~33% | Yes (stock) | Mixed |
FreeCell's combination of near-total solvability and zero hidden information makes it unique among solitaire games. Unlike Spider Solitaire, where unseen cards in the stock pile can doom your game regardless of skill, FreeCell gives you all the information you need from the very first deal. Your success depends entirely on your decisions.
Baker's Game — FreeCell's direct ancestor — has a much lower solvability rate (~75%) because it requires same-suit building instead of alternating colors. This restriction dramatically reduces the number of valid moves at any point. Explore all the differences on our solitaire types page.
♠Mathematical Analysis
Total Possible Deals
A standard 52-card deck can be arranged in 52! (factorial) ways — roughly 8.07 × 1067 permutations. In FreeCell, cards are dealt into 8 columns (4 columns of 7 cards and 4 columns of 6 cards). Since the order within each column matters but the assignment to columns follows a fixed pattern, the number of distinct FreeCell deals is approximately 1.75 × 1064. That's more arrangements than atoms in the observable universe — you will never play the same random deal twice.
Supermove Theory
The supermove is the mathematical engine that makes FreeCell solvable. The maximum number of cards you can move in a single logical operation follows this formula:
Max cards = (1 + free cells) × 2empty columns
Why More Free Cells = Exponentially More Power
The formula reveals why empty columns are so much more valuable than free cells. Each empty column doubles your maximum move size because it can serve as a temporary staging area for an entire sequence, not just a single card. This exponential relationship is why the strategy guide emphasizes keeping columns empty above all else.
In mathematical terms, each free cell adds linearly to your capacity (+1), while each empty column multiplies it (×2). Going from 0 to 1 empty column with 4 free cells jumps you from 5 to 10 cards — a 100% increase from a single column. This is why filling your last empty column is often a game-ending mistake.
