Is Every Game of Solitaire Winnable?

The short answer is no — and the reasons why are more interesting than you might expect.

Whether a given solitaire deal is winnable is not just a matter of playing well. Some games have deals baked into the shuffle that are mathematically impossible to solve, full stop. Others are theoretically winnable in nearly every configuration but require planning depth that most players never reach. A few sit somewhere in between, where luck and skill interact in ways that even researchers have struggled to fully model.

I’ve spent years building and playing all of these games for Card & Puzzle, and the question of winnability has been a consistent undercurrent in how I think about each one. Here’s what the data actually shows.

The Short Answer: Not Every Deal Is Winnable

No, not every game of solitaire is winnable — but the degree of unwinnability varies dramatically between games.

Some variants, like FreeCell, are winnable in almost every configuration. Some, like TriPeaks, are winnable the vast majority of the time. Others, like Spider 4-Suit and Pyramid, have substantial fractions of deals that are genuinely unsolvable, and even the “winnable” deals may exceed what most players can execute.

The answer also depends on whether you mean theoretically winnable (with perfect play) or practically winnable (as a realistic outcome for real players). Those numbers diverge sharply in the harder games. FreeCell is theoretically winnable in 99.999% of deals but has a casual win rate around 30–35%, because perfect play is not trivial to achieve. Klondike Turn 1 has roughly 10% unwinnable deals (about 18% for Turn 3), but even among the winnable ones, the average player loses far more than they win.

Solitaire Win Rates by Game

These figures represent the solitaire games available at Card & Puzzle, with casual win rates reflecting typical player performance rather than computer-optimal play. Where known, theoretical winnability — the percentage of deals that can be won with perfect play — is included. Some games have been studied rigorously by computer solvers; others have not, and their theoretical winnability remains unknown.

*Pyramid’s theoretical winnability of ~5.5% comes from computer analysis of 2 million deals under strict rules requiring all 52 cards to be cleared. Under rules that only require clearing the 28 pyramid cards (as in our implementation), the figure would be higher — but no rigorous study has established the exact number.

†Yukon’s ~70–75% figure is widely cited across solitaire reference sites but has not been confirmed by a peer-reviewed solver study.

Theoretical winnability data comes from several sources: Klondike figures from Blake & Gent’s peer-reviewed paper in the Journal of Artificial Intelligence Research (2026); FreeCell from exhaustive analysis of Microsoft’s original numbered deal sets; TriPeaks from computer analysis by the game’s inventor, Robert Hogue; Golf from Politaire’s experimental analysis of 100,000 deals; Addiction/Gaps from Mark Masten’s solver analysis; and Pyramid from Solitaire Laboratory’s simulation of 2 million deals.

A few things stand out in this table. The gap between FreeCell’s casual win rate (30–35%) and its theoretical winnability (99.999%) is the most dramatic in the entire set. FreeCell is not a hard game in the sense that most deals are unsolvable — it is hard because solving winnable deals requires planning that most players do not sustain. Addiction 7 is solvable in ~86% of deals, and its reduced deck (only Ace through Seven — 28 cards) plus two shuffles makes it one of the more approachable games despite its unique mechanic. Spider 4-Suit’s theoretical winnability has never been rigorously established due to the enormous computational complexity of analyzing two-deck, four-suit games — making it one of the few popular solitaire variants where nobody knows what percentage of deals are actually winnable.

Why Some Games Are Almost Always Winnable

Two structural factors explain why games like FreeCell and TriPeaks have win rates near the ceiling.

Full information eliminates luck from the deal. FreeCell starts with all 52 cards face-up and visible. There are no hidden cards to reveal at the wrong moment, no stock draws that produce the wrong card when you need a specific one. Because you can see everything, the game becomes a pure planning puzzle — and most planning puzzles have solutions. Of Microsoft’s original 32,000 numbered FreeCell deals that have been exhaustively analyzed by computer, only one (Deal #11982) is confirmed unsolvable. The rest are there to be solved if you can see the path. Broader analysis of millions of random deals confirms that FreeCell is nearly always winnable in general — not just within Microsoft’s set. That is as close to “every deal is winnable” as any solitaire game gets.

Generous card access rules create more paths through the puzzle. TriPeaks allows you to remove any card at the edge of a peak that is one rank adjacent to the current waste card — regardless of suit. That single rule creates a very wide solution space. At any given moment, there are typically multiple exposed cards that qualify for removal, and the waste card connects naturally to a wide range of values. The Kings-and-Aces wrap-around in our implementation adds further connectivity. Dead ends still happen, but they are less common than in games with stricter access rules.

Golf benefits from similar logic: no suit restrictions on chain building means a 5 on the waste card can chain to any 4 or 6 anywhere on the board. The constraint is purely about rank adjacency, which is far more permissive than suit-plus-rank rules.

Why Some Games Are Almost Never Winnable

The games at the bottom of the table share different failure modes, but they converge on the same result: a large fraction of deals cannot be won, and skill cannot overcome the structural impossibility.

Combinatorial complexity creates irresolvable configurations. Spider 4-Suit uses two decks across four suits in ten columns. To win, you must build eight complete King-to-Ace runs, each in a single suit, and remove them from the tableau. The constraint is that only same-suit sequences can be moved as a unit. Mixed-suit sequences cannot. This means that separating and isolating each suit requires moving individual cards across the tableau repeatedly — and with 104 cards in play, the number of configurations that produce unsolvable entanglements is enormous. A card of one suit buried beneath multiple cards of other suits, with no empty columns available to stage the reorganization, can create a permanent deadlock.

The theoretical winnability of Spider 4-Suit has never been rigorously established — the computational complexity of analyzing two-deck, four-suit games exceeds what current solvers can handle. What is clear is that a meaningful fraction of deals are unwinnable, and even among winnable deals, executing the solution requires holding a mental model of the entire board state while orchestrating multi-step sequences across multiple suits simultaneously. It is the closest thing to a combinatorial puzzle that solitaire gets.

Structural lock mechanics create circular dependencies. Pyramid arranges 28 cards in a triangular formation where lower-row cards cover upper-row cards. A card is only accessible when both cards overlapping it from the row below have been removed. You clear cards by pairing any two exposed cards that sum to 13. The problem is that the arrangement of the pyramid can create circular dependencies: removing Card A requires removing Card B first, but removing Card B requires removing Card C, and removing Card C requires removing Card A. This circular structure is not recoverable through additional moves — the configuration is simply locked, and no amount of creative play can unlock it.

Addiction 7 is an interesting counterpoint. An estimated 85–90% of deals are theoretically solvable, and the reduced deck — only Ace through Seven, 28 cards total — keeps the puzzle compact and readable. A gap that appears to the right of a Seven cannot be filled by any card, which can stall a row, but two shuffles are available to reorganize unplaced cards and break through stuck positions. Despite its unusual mechanic, Addiction 7 is one of the more approachable games at Card & Puzzle — the small grid and shuffle safety net make it easier than the traditional Gaps/Montana format that inspired it.

Skill vs Luck in Solitaire

Every solitaire game has some mixture of luck (the initial shuffle) and skill (the quality of play decisions). But the ratio varies enormously, and the games at the extremes behave very differently.

High luck influence, lower skill ceiling: TriPeaks and Golf are most influenced by the initial deal. A favorable shuffle produces long chains and easy clearances regardless of play quality. An unfavorable shuffle creates isolated stub columns that no amount of clever play can salvage. Skill still matters — correctly sequencing removals and reading ahead to maximize chain length separate good players from lucky ones — but the ceiling on skill impact is lower than in the planning-heavy games.

Low luck influence, high skill ceiling: FreeCell is the clearest example in this direction. There is essentially no randomness in the game after the deal — all information is visible, and the outcome is determined entirely by the quality of decisions. A skilled FreeCell player who plans 10–15 moves ahead will win the vast majority of games. A casual player who locks their free cells early and runs out of maneuvering room will lose games that were easily winnable. The same deal, played differently, produces opposite outcomes.

Both factors matter, unevenly: Klondike Turn 1 is where the luck-versus-skill question gets genuinely complicated. A meaningful fraction of Klondike deals are unwinnable regardless of play — roughly 18% under standard rules — and that is pure bad luck with no remedy. But among the winnable deals, skill is highly determinative. An experienced player minimizing premature foundation play, carefully sequencing tableau moves, and managing the stock efficiently will win a substantially higher fraction of those winnable deals than a casual player making reactive moves.

Yukon and Pyramid behave similarly: a mix of deals where skill cannot matter because the configuration is unsolvable, and deals where skill is the primary determinant of whether the game gets completed.

The practical upshot is that the “luck” component of any solitaire game operates at the deal level — it determines whether a winnable path exists — while the “skill” component operates at the decision level — it determines whether you find and execute that path. Improving at solitaire means getting better at the skill component. You cannot control the luck component at all — unless you remove it entirely.

Every solitaire game at Card & Puzzle deals winnable hands by default — every deal you receive is guaranteed to have a solution. If you lose, the problem was your play, not the shuffle. This keeps frustration down, especially for newer players, and means your win rate is a pure measure of skill rather than luck. If you prefer the traditional experience — including the possibility of unwinnable deals — you can choose a random deal when starting a new game.

How to Choose the Right Solitaire Game

At Card & Puzzle, the default winnable deals already eliminate the frustration of unwinnable shuffles. Beyond that, play the games with higher theoretical winnability and lower skill ceilings. TriPeaks is the right choice: an 85% casual win rate means the vast majority of sessions end in a satisfying win, and the game is forgiving enough that moderate mistakes do not cascade into inevitable losses.

If you want to improve and earn wins through genuine skill, FreeCell is uniquely well-suited to that goal. Almost every deal you will ever encounter is winnable — which means every loss is information about where your planning broke down, not bad luck. That feedback loop is valuable. The FreeCell Solitaire Guide is a good place to start building the planning instincts the game requires.

If you want a middle ground — games that are genuinely challenging but where a good session produces several wins — Klondike Turn 1 and Golf sit comfortably in that range. You will lose often enough to feel the difficulty, but win often enough to stay motivated. See the Klondike Solitaire Guide and Golf Solitaire Guide for strategy that meaningfully improves performance in both.

If you want to test yourself at the extreme end, Spider 4-Suit is the challenge to chase. Do not expect to win often — win rates under 10% are typical even for experienced players. But clearing a 4-Suit game after a long, careful session produces a satisfaction that easier games simply cannot match.

If you want something different entirely, Addiction 7 is a compact spatial puzzle — only 28 cards, a grid layout, and two shuffles to help you through. It is one of the easiest games at Card & Puzzle and a great change of pace from tableau-building games.

Frequently Asked Questions

Is every game of solitaire winnable?

No. In most solitaire variants, a percentage of deals are mathematically unwinnable regardless of how well you play. Klondike Turn 1 has roughly 10% unwinnable deals; Turn 3 has about 18%. Pyramid has a very low theoretical winnability under strict rules. The exception is FreeCell, where only one deal in Microsoft’s original numbered set (Deal #11982) is confirmed unsolvable — the rest can be won with correct play. Broader analysis confirms FreeCell is nearly always winnable in general.

What percentage of solitaire games are winnable?

It varies significantly by game. FreeCell is theoretically winnable in 99.999% of deals. TriPeaks is winnable around 90–95% of the time under optimal play. Klondike is winnable in roughly 82% of deals under standard (Turn 3) rules, with Turn 1 having better odds — though casual win rates are far lower due to mistakes. Spider 4-Suit’s theoretical winnability has never been rigorously established due to computational complexity. Exact figures are not known for all variants.

What is the easiest solitaire game to win?

TriPeaks Solitaire has the highest casual win rate of any common solitaire variant, around 85% for most players. Golf Solitaire is close behind at 65–70%. Both have generous mechanics and tend to reward casual play without punishing small mistakes as severely as the tableau-building games do.

What is the hardest solitaire game to win?

Spider 4-Suit has the lowest casual win rate of any widely played solitaire variant — under 10% for most players, and below 5% for beginners. Pyramid is also very challenging, with casual win rates around 15–20% and many deals that are structurally unwinnable under strict rules.

Does skill matter in solitaire, or is it mostly luck?

Skill matters in every solitaire game, but the degree varies enormously. In FreeCell, skill is almost everything — almost every deal is winnable, so losses are nearly always due to planning errors. In TriPeaks and Golf, luck from the initial shuffle has a larger influence, but correct card selection and sequencing still separates experienced players from casual ones. Spider 4-Suit demands very high skill, and luck still determines a portion of outcomes regardless of quality of play.
