You don't think so? Try 11982. It never has been solved. Only one in a million that is unsolvable.
Myself I have won every game from 1-25,000 excluding 11982 which is impossible. This is using FREECELL CLASSIC not the version I'm seeing here. I tried the new version, found it too slow. Had to find old version and install. Of course when doing this the WINs and losses reset to zero. But I do have excel file with amount of time to win each of the 25,000 games.
http://www.solitairelaboratory.com/fclists.html Thsi list show 6) Laura Ross of Omaha, Nebraska played all 32,000 deals, solving all but five of the deals (8591, the impossible 11982, 13007, 31465, and 31938). She found 617 and 1941 the most difficult of those she solved.
My fear was he would lose control and go careening down that hill the trail is on.
Needs a slo-mo with sound so can tell if this is a record or not
