FreeCell is a Solitaire game that is played with a standard 52-card of playing cards. FreeCell is different from other solitaire games in the sense that all cards are face-up from the beginning of the game, which makes the outcome of the game depend more on skills than luck.
To win the game, a player has to stack all cards onto four foundations, sorted by a cards suit and number, starting from the ace and ending with the king.[1]
FreeCell is considered to be one of the easier types of solitaire since the vast majority of games are winnable.
