History of FreeCell
FreeCell was invented in 1978 by Paul Alfille, who programmed it for the PLATO educational system at the University of Illinois. Its defining innovation was making every card visible from the first move — unlike Klondike, there is no hidden information and almost no luck. The game became a worldwide phenomenon after Microsoft bundled it with Windows 3.1 in 1992 and Windows 95 in 1995.
Microsoft’s original implementation numbered deals 1 through 32,000. Of those, exactly one deal — number 11,982 — is provably unwinnable. Every other deal can be solved. This makes FreeCell unusual: a lost game is almost always a missed line of play, not an unlucky shuffle.
Full rules
FreeCell uses a single 52-card deck. All cards are dealt face-up into eight tableau columns — four columns of seven cards and four of six. Above the tableau sit four free cells (each holds one card) and four foundation piles (one per suit, built Ace through King).
Tableau columns build downward in alternating colors. You may move one card at a time, but any sequence of cards that could legally be moved one by one — using free cells and empty columns as staging — can be treated as a single move. This is called a supermove: the number of cards you can move at once equals (free cells open + 1) × 2 raised to the power of empty columns.
How FreeCell differs from Klondike
Klondike hides most of the deck in face-down cards and a stock pile, so every draw introduces new information and uncertainty. FreeCell removes both of these elements entirely: all 52 cards are visible from deal one, and there is no stock.
The result is that FreeCell rewards planning over luck. In Klondike, a bad deal genuinely limits your options. In FreeCell, a stuck position almost always means a better line of play exists somewhere on the board. Players who enjoy pure strategy and complete information tend to prefer FreeCell. Players who enjoy the tension of hidden reveals often prefer Klondike.
Key strategic concepts
The most important skill in FreeCell is space management. Free cells and empty columns are both temporary storage, but an empty column is worth more — it can hold multiple cards staged through it in sequence, where a free cell holds only one. Never fill all four free cells simultaneously; doing so limits you to moving exactly one card at a time.
Before making any sequence of moves, check the supermove formula. A plan that requires moving eight cards but only grants four cards of effective mobility is not executable. Preparing the space first — then executing — is the hallmark of strong FreeCell play.

FreeCell variants
- Penguin— A FreeCell variant where all cards of one suit are removed before dealing, and seven free cells (“flippers”) replace the standard four. The opening rank (the “beak”) shifts all foundation and tableau start points, creating a very different board feel.
- Beleaguered Castle — A pure open-packer with no free cells at all. Aces start on foundations; the 48 remaining cards fill eight columns. Every card is visible, but without free cells the ordering puzzle is much harder.
