I have been enjoying these puzzles with commercial attachments. It is a lot of fun to watch the old ads - I think I enjoy them much more than the in-your-face advertising of today.#3: valerie o..travis (bigblue) on Sep 17, 2012
I have a question. When the system asks you to rate "solvability", I do not quite understand the terms. The trivial vs line logic vs moderate vs deep lookahead. Can anyone explain the differences to me, or is there a forum on the site where this has been discussed please? Sorry to ask such a long question in the comments section - wasn't sure where else to go. Thank you!

Very good. I enjoy these, too.

Thank you Kristen! I just read the topic you listed, and it did indeed explain alot! Much obliged.#7: Jota (Jota) on Sep 17, 2012

to much new years partying, Jota?#9: Jota (Jota) on Sep 17, 2012
Indeed!#10: Tom King (sgusa) on Sep 17, 2012 [HINT]
Fun puzzle, Tom. It requires smaile logic in the upper left which is a moderate look ahead.#11: Tom O'Connell (sensei69) on Sep 18, 2012
thx Tom#12: Web Paint-By-Number Robot (webpbn) on Sep 21, 2012
Found to be solvable with moderate lookahead by gator.#13: Tom O'Connell (sensei69) on Sep 21, 2012
thx Gator#14: Bruce Yanoshek (yanogator) on Feb 2, 2017
I'm not sure that's smile logic, Tom (although I'm still confused on exactly what smile logic is). When you get to that point, there are 5 cells and the middle one is filled. If you fill the 2 to the left, then there isn't room for the three 1s. Likewise for the 2 to the right, so the 3 have to be in the middle of the 5 cells. That's edge logic, isn't it?#15: Gary Webster (glwebste) on Feb 2, 2017 [HINT]
I guess I don't call smile logic "lookahead." It's a form of line logic to me...#16: Joe (infrapinklizzard) on Aug 25, 2017 [HINT]
All logic requires lookahead. Some is trivial: if this, then that. Line logic and color logic are the baseline since all puzzles need some of these. Moderate lookahead is when you need to look at more than one line at a time using advanced logic. (See http://webpbn.com/index.cgi?page=solving.html for an explanation of the logic terms we use here.) If the solving requires more than that, but has a demonstrated solve (not just a statement that "I solved it with logic"), then it gets labeled deep-lookahead. If nobody can lay out a solve, or if there are multiple solutions, then it gets one of the guessing-needed labels.#17: Tom O'Connell (sensei69) on Aug 27, 2017
This puzzle is definitely not line logic solvable. Line logic uses clues from only one line at a time.
It is definitely a form of smile logic. The way it goes is: if the 3 in r1 goes right all the way to c6, then there would not be enough room in r3 for the three 1s. Therefore that can't happen and so r1c6 must be white.
thx Joe ... now I don't have the blahs anymore :D
