Free Cell is one of the most popular computer solitaire games.
- All cards are dealt to eight stacks.
- You can move only one card at a time.
- You can move a card to another stack if the card is one less in value and of an alternate color.
- You can move cards to foundations by ascending value, by suit, starting with aces.
- Four 'free cells' allow you to place single cards for temporary storage.
- If a stack is emptied, you can move any one card to fill the space.
