Solitaire Rules:

Set-Up: The first four stock cards of different ranks are dealt to the second foundation row. Each of them has a space for its "twin" card beside it, forming another foundation.

Foundations (16 piles: complete these piles to win the game)

There are 16 foundation piles, forming 2 rows of 8 foundations each.

Upper row

  • In the upper foundation row, building is alternate by couple:

    • build the first and the third couples up regardless of suit (for example, a 5 can be played on a 4) from the base card until each pile contains 12 cards;

    • build the second and the fourth couples down regardless of suit (for example, a 10 can be played on a Jack) from the base card until each pile contains 12 cards.

  • No building is allowed in the upper foundation row until the corresponding 2 foundations below it in the lower row contain the "twin" cards.

  • No building is allowed on a foundation that does not have its "twin" beside it. For example: having placed a Three on a Two, you can't build a Four until the other Two is covered with a Three.

  • Ranking of cards is continuous: build King after Ace when necessary.

  • At the end of the game, each of the 8 upper foundations will contain 12 cards.

Lower row

  • The lower foundation row will contain the base cards and its "twin".

  • Each of the 8 lower foundations will contain only one card.

Tableau (5 piles)

  • Place cards from the stock on any of these piles in any suit and in any rank, as advantageous.

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

  • Only one card at a time can be moved.

  • Spaces can be filled from the stock.


  • Turn up one card at a time from the stock to the waste by clicking.

  • One redeal is permitted (two deals in all).

Waste (One pile)

  • The top card is available for play to the foundations or to the tableau.
