FreeCell Solitaire

FreeCell shows you everything. All 52 cards lie face up from the first move, so nothing depends on luck once the deal is on the table. What remains is planning: how to untangle eight columns using four temporary parking spots. That is why FreeCell players talk about it as a puzzle more than a card game.

Rules step by step

  1. The deal. Eight columns, called cascades, are dealt face up. The first four hold seven cards each, the last four hold six.
  2. Free cells. Four cells sit above the table. Each holds exactly one card, and you can take it out again whenever you like.
  3. Foundations. Four piles, one per suit, build from ace to king.
  4. Build down in alternating colors. On a cascade, a card goes on a card one rank higher and of the opposite color. A black 5 fits on a red 6.
  5. Move one card at a time, or a run. Strictly, you move a single card. In practice you can move a whole ordered run if you have enough free cells and empty columns to shuffle it across, and the game does that for you in one step.
  6. Empty cascades. Any card, or any part of a run, can go into an empty cascade.
  7. Win when all four foundations hold thirteen cards.

How long a run can move

The limit depends on how much spare room you have. With n empty free cells and m empty cascades, the longest run that can move onto a cascade that already holds cards is (n + 1) × 2 to the power of m. Two empty cells and one empty cascade let you carry 3 × 2 = 6 cards. Moving onto an empty cascade, that cascade does not help, so the same room carries only 3 cards. The game checks this for you and refuses a run that is too long. A partial run is fine: if the full run is too long, you can move the lower part of it.

Scoring is deliberately plain. FreeCell counts your moves and your time, nothing else.

Frequently asked questions

Is every FreeCell deal solvable?

Not every random shuffle is. The deals offered here are drawn from a pool in which an offline solver found a winning line for every one. A solution exists, though finding it can still take thought. A deal that does not come from the pool is labelled as not checked.

Why does the game move several cards at once?

Dragging a run is a shortcut for many single moves through cells and empty cascades. The game checks that the room is there before it allows the move.

Can I undo a move?

Yes, without limit, and you can redo too. The hint shows a legal move, not necessarily a helpful one.

What is a good first move?

Look for an ace or a two near the top of a cascade. If none is reachable, count how many moves it takes to expose the closest one.

Is there a score?

Only moves and time. Fewer moves is the usual way to compare two wins.

If you like to think a few moves ahead, Pyramid rewards counting cards in a very different setting. Spider offers a longer test, and Klondike is the classic. The rules of each are on one page at how to play, and the shared puzzle of the day is on the daily page.

Deal pool facts

Counted from this game's deal files when the site is built. The about page explains how the pool is made.

Deals in the pool
1,500, each with a stored winning line that the site's tests replay through the game rules
Shuffles with a win found
1,500 of the first 1,501 tried, or 99.9 percent
Median winning line
100 steps
Middle half of winning lines
93 to 108 steps
Daily deal
Chosen in advance for each UTC date from a fixed shuffle of the pool. So far 400 days are scheduled, using 400 different deals.

A step is one move as the solver counts it, so the move counter on the table can show a lower number for the same line. These are the lines the solver found, and shorter wins may exist. Shuffles without a win inside the solver's limits were left out.
