Message:When I don't have time for streaking (which is most of the time, these days), I sometimes practice by playing through the 8x3 Level 7 unplayed/unsolved deals. If anyone is up for a challenge, you can join me in completing the set. As of right now, all deals through 3600 have been attempted.

is there anyway free@last could reduce the list to winnable but unwon? games with large number of attempts that turn out winnable might pique certain peoples interest.

Message:Most of them are winnable...there are only 73 total unwinnables in 8x3 - 7...so likely 8-14 impossibles in the 1st 5000.

How do you know how many are winnable?
Date: Sun Dec 3 21:59:10 2017
User: CubicSprock
Message:When developing the winnables variant free@last developed a program and ran it against all the games in many of the variants on this site. This program was unable to solve 73 of the 8x3 level 7 games. I've linked to a document with those totals below.
This 73 is really an upper limit, and the number is likely slightly less as there are likely a handful of games that are possible that the program couldn't solve. In 8x3 level 5, for example, the program couldn't solve 23 games, but only 17 are actually (presumed) impossible, meaning it failed on 6 winnable games.

2521 is now 1/14. It took me two tries. BTW all higher difficulty levels above 7 for this one have already been solved. I also did them and they were all pretty easy.
4312 is also now 1/14. It also took 2 or 3 tries.

Message:thank you for 2723! yes i knew 66 was solvable, i crunched all the remaining (at the time) games to know which ones were not a waste of time. interesting thing, all the games i typed into text files (i'm "between jobs" and a project was just the ticket) to check them had a king as the first card dealt. all of them.

Whoa Colt - you need to get all of your aliases playing at the same time. Looks like there are about 100 un-played deals per 1000 from the 8000's on up. Maybe Denny should track who wins an 8x4 deal without using that 4th freecell.
