FreeCell Stack app for iPhone and iPad

- The goal is to complete four stacks of same suit cards from A to K in the upper-right corner.

- Cards in the eight columns can be moved on to each other in descending order and must alternate between red and black. For example, you can put a black Q on a red K.

- In the upper-left corner are four free cells, where you can temporarily store any single card during play.

- Once you complete a card on top-right corner, you cant move it back.
- When moving a stack of sequential cards between the eight columns, the maximum number of moveable cards equal to the number of free cells available plus one.

- When you have an empty column, you can move any stack of cards there as long as you have enough free cells allowing you make the move.
