FreeCell is a classic solitaire variant. All 52 cards are visible from the start — every deal is a pure puzzle with no hidden information.
FreeCell is a classic solitaire variant played with a single 52-card deck. Unlike Klondike, every card is visible from the start — there is no hidden stock and no luck-of-the-draw. Roughly 99% of all deals are solvable with the right strategy, so winning is a question of planning, not chance.
FreeCell rewards planning over pattern-matching. Every card is visible from the start, so every loss is a decision made, not a card not drawn. What follows is the practical playbook — the habits that take you from "most deals are unsolvable" to "I win every hand."
Almost. Roughly 99.99% of all 52-card FreeCell deals have a known solution. The famous outlier from the Microsoft 1–32000 catalog is deal #11982 (plus a handful of others like #146692, #186216, #455889, #495505, #512118) that have been verified by computer to be unsolvable. StillDeck supports Microsoft-numbered deals via /freecell/?deal=N.
A deal is unsolvable when no sequence of legal moves reaches a full foundation state. The canonical unsolvable pattern is when a card is buried under every card you'd need to move to expose it — and you don't have enough free cells plus empty columns to break the cycle. The supermove formula (1 + free cells) × (1 + empty columns) caps how many cards you can shift at once, so some positions simply can't be unfolded.
Four big differences. First: no stock or waste pile — every card is visible from the start, so there's no luck of the draw. Second: four free cells serve as temporary single-card holding slots. Third: empty tableau columns accept any card in FreeCell (Klondike restricts them to Kings). Fourth: FreeCell rewards planning over pattern-recognition; Klondike rewards persistence.
