FreeCell has been bundled with all versions of Windows since 95 . The term "FreeCell" is given to the four empty spaces above the tableau that are used for the temporary storage of cards. The rules only allow you to move one card at a time but the FreeCells can be used to move sequences of packed cards between tableau columns. All the cards are dealt face up at the start of the game and this lets you analyze the outcome of moves before you make them.
