Description Peter Barth 2010-03-11 19:52:38 UTC 
Version:            (using KDE 4.3.5)
Compiler:          gcc 4.3.4 
OS:                Linux
Installed from:    Gentoo Packages

There are cases in Freecell which make the solver report a game to be not winnable anymore even though it still is winnable.

I do not see an obvious reason what the solver is missing here, so I made screenshots of the game in question. Mind that I had set a german locale, it translates like that:

"Dieses Spiel kann nicht mehr gewonnen werden" <-- it's _not_ winnable
"Dieses Spiel kann (noch) gewonnen werden" <-- it's (still) winnable

(Sorry, my first kde bugreport, I hope I'll manage to actually attach the screenshots after creating that report :))

Now even solver got it: The game is sill winable
Comment 4 Parker Coates 2010-03-11 22:20:42 UTC 
Unfortunately, screenshots are no good to us. Can you recreate the situation and attach a saved game?
Comment 5 Peter Barth 2010-03-11 22:45:44 UTC 
Oh, never recognized there's a save button :*)
Situation recreated and saved.

SVN commit 1217229 by coolo:

freecell was never a game where empty piles allowed only
kings. I wonder how many games still could be solved
