Freecell Solitaire in a click of a button, play directly in Chrome.

FreeCell is a solitaire card game played using the stard 52card deck. It is fundamentally different from most solitaire games in that very few deals are unsolvable,  all cards are dealt faceup from the very beginning of the game. Although software implementations vary, most versions label the hs with a number (derived from the seed value used by the rom number generat to shuffle the cards).

** Rules **
>> Construction  layout
One stard 52card deck is used.
There are four open cells  four open foundations. Some alternate rules use  one  ten cells.
Cards are dealt faceup into eight cascades, four of which comprise seven cards  four of which comprise six. Some alternate rules will use  four  ten cascades.

>> Building during play
The top card of each cascade begins a tableau.
Tableaux must be built down by alternating cols.
Foundations are built up by suit.

>> Moves
Any cell card  top card of any cascade may be moved to build on a tableau,  moved to an empty cell, an empty cascade,  its foundation.
Complete  partial tableaus may be moved to build on existing tableaus,  moved to empty cascades, by recursively placing  removing cards through intermediate locations. Computer implementations often show this motion, but players using physical decks typically move the tableau at once.

>> Victy
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


** Histy **
One of the oldest ancests of FreeCell is Eight Off. In the June 1968 edition of Scientific American, Martin Gardner described in his "Mathematical Games" column a game by C. L. Baker that is similar to FreeCell, except that cards on the tableau are built by suit rather than by alternate cols. Gardner wrote, "The game was taught to Baker by his father, who in turn learned it from an Englishman during the 1920s."[This variant is now called Bakers Game. FreeCells igins may date back even further to 1945  a Scinavian game called Napoleon in St. Helena (not the game Napoleon at St. Helena, also known as Fty Thieves).

Paul Alfille changed Bakers Game by making cards build accding to alternate cols, thus creating FreeCell. He implemented the first computerised version of it in the TUTOR programming language f the PLATO educational computer system in 1978. Alfille was able to display easily recognizable graphical images of playing cards on the 512 × 512 monochrome display on the PLATO systems.

This iginal FreeCell environment allowed games with 4–10 columns  1–10 cells in addition to the stard 8 × 4 game. F each variant, the program sted a ranked list of the players with the longest winning streaks. There was also a tournament system that allowed people to compete to win difficult hpicked deals. Paul Alfille described this early FreeCell environment in me detail in an interview from 2000.

In 2012, researchers used evolutionary computation methods to create winning FreeCell players.

** Solver complexity **
The FreeCell game has a constant number of cards. This implies that in constant time, a person  computer could list all of the possible moves from a given start configuration  discover a winning set of moves , assuming the game cannot be solved, the lack thereof. To perfm an interesting complexity analysis one must construct a generalized version of the FreeCell game with 4 × n cards. This generalized version of the game is NPcomplete; it is unlikely that any algithm me efficient than a brutefce search exists that can find solutions f arbitrary generalized FreeCell configurations.

There are 52! (i.e., 52 factial),  approximately 8×1067, distinct deals. However, some games are effectively identical to others because suits assigned to cards are arbitrary  columns can be swapped. After taking these facts into account, there are approximately 1.75×1064 distinct games.

We hope you enjoy the game :)
