Gypsy
Gypsy type. 2 decks. No redeal.
Object
Move all cards to the foundations.
Rules
The eight playing piles in the tableau all start with two cards face-down and one showing. Piles build down by alternate color, and an empty space can be filled with any card or sequence.
When no more moves are possible, click on the talon. One card will be added to each of the playing piles.
You are also permitted to move cards back out of the foundation.
Strategy
Making heavy use of the Undo key is explicitly encouraged here - you can win quite a number of games with a little bit of thought.
History
Gypsy is my all time favorite - it is probably the reason that I started writing PySol at all...
I first met Gypsy almost fifteen years ago in the nice Atari ST game Patience written by Volker Weidner. And as there seems to be no official name of this variant I adopted the name Gypsy from another game called xpat2.
