This is a two-deck patience. The game begins with dealing four Kings and four Aces to the foundations arranged as a cross. Then 12 cards are dealt face up to the reserve. The remaining cards form the stock.
The object of the game is to build eight foundation piles: down in suit on Kings and up in suit on Aces. As a result, the cross must be shifted: Aces must change places with Kings.
Only the top cards of the tableau are available to play.
After you have exhausted all the plays among the reserve and foundations, click the stock. If there are empty spaces in the reserve, new cards are dealt only to them, if not - 12 new cards are dealt to form a new layer of the reserve.
After the stock has been exhausted, click the stock cell to collect the reserved cards. Now you can deal them again.
The stock can be collected twice.
