Solitaire Rules

  • An Ace and a King of each suit are removed from the stock to become the foundations.

Foundations (8 piles: complete these piles to win the game)

  • Build the Ace foundations up in suit from Ace to King (for example, a 2 can be played on an Ace).

  • Build the King foundations down in suit from King to Ace (for example, a Queen can be played on a King).

Reserve (20 cards in 4 rows of 5 each)

  • The top card of each pile is available for play on the foundations only.

  • If any of the original 20 cards is moved to a foundation, the space is automatically filled from the stock (except as to the original deal, spaces in the reserve are not filled automatically).

  • There is no movement on these piles.


  • Deal and place one card at a time from the stock to any reserve pile until 20 cards have been dealt (refer to the counter underneath the cards).

  • You may not move any card to a foundation pile until the current group of 20 cards have been dealt. Once the counter has been reset to 0 (it will read 0/20) move as many cards as possible to the foundations before dealing the next set of 20 cards.

  • There is no redeal.
