Variations of the basic game of FreeCell solitaire include HardCell, Klondike FreeCell and Napoleon in St Helena. Some games that predate FreeCell are considered to be prototypes that helped inventor Paul Alfille to create it are the Baker's Game and Eights.
Basic FreeCell is played in eight columns of cards face up with four free cells. Variations developed by Alfille adjust the number of columns to anywhere from four to 10, and also adjusts the number of free cells anywhere from one to 10. HardCell increases the difficulty of the game by placing 20 of the cards in the eight columns face down. Napoleon in St Helena dates back to 1945 and varies game play by dealing the last four cards to each of the four free cells instead of to the eight columns.
