The goal is to move all the cards to the foundations in ascending order by suit.
You can only grab one card at a time and move it from one tableau pile to another in descending order by suit.
When a tabluea pile is empty, you cannot move new cards there.
By pressing the empty stock pile at the upper left, you can collect and redeal the cards in the tableau. The cards will not be shuffled, but will be placed back into the tableau in piles of 4 until no more cards are left. You can do this as many times as you want.
