Is FreeCell always winnable?
FreeCell's reputation as the near-always-winnable solitaire is well earned, though 'always' isn't quite the right word.
The near-perfect win rate
Because FreeCell deals every card face up with no hidden information, an astonishing share of deals, roughly 99.999%, can be solved. A tiny fraction resist any line of play. For context on how that compares with other games, see what percentage of solitaire is winnable, where FreeCell sits at the very top.
The famous unwinnable deal
The classic Microsoft FreeCell shipped 32,000 numbered deals, and enthusiasts eventually proved that exactly one of them, deal #11982, cannot be won. A few others were later shown unsolvable when the set was expanded, but for practical purposes almost every deal you'll ever see is winnable.
What this means for you
The takeaway is simple: if you lose a FreeCell game, it was almost certainly a mistake, not the shuffle. That's what makes it such a clean skill test, and why using undo to find where you went wrong is a legitimate learning tool. Sharpen up with how to win FreeCell.

What is FreeCell?
FreeCell is a solitaire variant in which all 52 cards are dealt face up from the start, and four 'free cells' let you set cards aside temporarily. Because there's no hidden information and about 99.999% of deals are winnable, it's the purest test of skill in the genre.
What percentage of solitaire games are winnable?
It varies enormously by variant. About 99.999% of FreeCell deals are winnable with perfect play, roughly 80% of Klondike Turn 1 deals, around 80% of Yukon deals, and only about 20% of strict-rules Pyramid deals. Real win rates are much lower than these theoretical ceilings.
Is solitaire luck or skill?
It is both, and the balance depends on the game. The shuffle decides whether a deal can be won at all, but skill decides whether you actually win it. FreeCell is almost pure skill because every card is visible, while Klondike mixes luck of the draw with real decision-making.
