Line up cards by suit from Ace to King. Two packs of cards are used.
One pack of cards is dealt to the working spaces, and the second pack is used for the stock. Tap on the stock to turn over one card at a time. The stock can only be dealt through twice. The stock card shown indicates which single card in the working spaces can be swapped. That card can be swapped by tapping on another card either horizontally or vertically in line with it.
