FreeCell Solitaire Classic 2019

In the Freecell version of Solitaire we have to sort 4 card decks. As an help we can use the free cells to discard cards temporary. The goal is to sort all decks from ace to king in the same suit on the right side of the playing grid.

Construction and layout

One standard 52-card deck is used.

There are four open cells and four open foundations. Some alternate rules use between one and ten cells.

Cards are dealt face-up into eight cascades, four of which comprise seven cards each and four of which comprise six cards each. Some alternate rules will use between four and ten cascades.

Building during play

The top card of each cascade begins a tableau.

Tableaux must be built down by alternating colors.

Foundations are built up by suit.

Moves

Any cell card or top card of any cascade may be moved to build on a tableau, or moved to an empty cell, an empty cascade, or its foundation.

Complete or partial tableaus may be moved to build on existing tableaus, or moved to empty cascades, by recursively placing and removing cards through intermediate locations. Computer implementations often show this motion, but players using physical decks typically move the tableau at once.

Victory

The game is won after all cards are moved to their foundation piles.

Not all deals are solvable, but the probability of an unsolvable deal is very low. It is estimated that 99.999% of possible deals are solvable. Deal number 11982 from the Windows version of FreeCell is a widely known example of an unsolvable FreeCell deal, and the only deal among the original "Microsoft 32,000" which is unsolvable.
