FreeCell.
Eight columns, four free cells, every card face up. Nearly every deal can be won.
Dealing the cards…
How to play
Build each foundation from ace to king in one suit. In the columns, stack cards downward in alternating colours.
Park a card in a free cell when you need room. Empty cells and columns let you move longer runs at once. Pick a numbered deal to replay one you love.
