FreeCell Spider is a variation of classic FreeCell where the objective is to make runs from King down to Ace in alt-colored suits. Since this is more challenging than the traditional objective of building foundations, a couple extra free cells have been added.
All four versions are fully functional and free-to-play, no in-app purchases.
You can play the easier 6Cell game, or the progressively harder 5Cell, 4Cell and 3Cell.
