Once you and your opponent are done with the layout, both can start playing regular Solitaire. Which means, you arrange sequences of cards in the tableau in a descending order, wherein, you must place a card of the red suit under a black, and vice versa. For instance, King of Spades – Queen of Hearts – Jack of Clubs. In case you don’t find a suitable move, you can always resort to the stock pile.
Build the Foundation Area
Simultaneously, you can also build up the common foundation pile in an ascending order, viz starting with the Aces. However, here, you are supposed to strictly follow the suit. You cannot place a 2 of Spades over an Ace of Hearts.
As the foundation area is common for both, you can place a card over another which has been placed by your opponent. For instance, if the opponent places the Ace of Diamonds in the foundation area, you can very well place a Two of Diamonds over it, if you have it at your disposal.
How to End
The game ends either with a player exhausting his/her deck by successfully sequencing them in the foundation area, or if both the players run out of legal moves. In the latter case, the cards in the foundation area are counted separately as per their respective decks; the player whose deck is found to have the highest number of cards wins.
Some variations to the game could be drawing three instead of one card from the stock pile, or vice versa. Also, setting a fixed time to finish the game could make it more challenging.
Informal Playing Conditions
Players must place only one card at a time on any of the foundation stacks. If both the players try to place a card on the same foundation stack, the card that was placed first stays on the stack, and the other goes back to the respective player.
