At a glance

A combination of Yukon type and Calculation type game elements.

How to play

The four Foundations build up by suit the following way: The first pile from Ace, by one. The second pile from Two, by two. The third pile from Three, by three. The fourth pile from Four, by four. 

Club:     A 2 3 4 5 6 7 8 9 T J Q K
Spade:    2 4 6 8 T Q A 3 5 7 9 J K
Heart:    3 6 9 Q 2 5 8 J A 4 7 T K
Diamond:  4 8 Q 3 7 J 2 6 T A 5 9 K

Cards in Tableau are built down by suit, the ranks going the opposite way as the foundations: Club down by one, Spade down by two, Heart down by three and Diamond down by four.

Groups of cards can be moved regardless of sequence, and an empty space can be filled with any card or sequence.

When no more moves are possible, select the Talon. One card will be added to each of the playing piles.

How to play

Cards in tableau are built down by alternate color. Groups of cards can be moved regardless of sequence. An empty pile in the tableau can be filled with a King or a group of cards with a King on the bottom.

Foundations are built up in suit from Ace to King. Cards in foundations are no longer in play.

Base game rules: Calculation

Goal

Move all cards to the foundations.

How to play

Cards are dealt from the talon one at a time, and can be played to the foundations.

The four foundations build regardless of suit the following way: The first pile from Ace, by one. The second pile from Two, by two. The third pile from Three, by three. The fourth pile from Four, by four. 

1:  A 2 3 4 5 6 7 8 9 T J Q K
2:  2 4 6 8 T Q A 3 5 7 9 J K
3:  3 6 9 Q 2 5 8 J A 4 7 T K
4:  4 8 Q 3 7 J 2 6 T A 5 9 K
Once on a stack, a card can only be moved onto a foundation. The game is won when all cards are moved to the foundations.
