I could not figure out what it was until I saw the description... interesting design though.#2: paul dahmer (paul) on Apr 6, 2008
requires no guessing!!!!!!!!!!!!!!!!!!!!!!!!!!!#3: Jan Wolter (jan) on Apr 8, 2008
I had to guess.#4: Nancy Snyder (naneki) on Apr 11, 2008
I love the guessing/no guessing that goes on here..lol#5: JoDeen Mozena (ozymoe) on Apr 11, 2008 [HINT]
Good puzzle Thank you :)
I'm not sure if I "guessed" or not. I solved well over half (starting with the bottom)...then, after doing all the edge logic, I started checking some of the "internal patterns". I actually call that guessing...and I really dislike having to resort to that (which I call guessing) in an otherwise wonderful puzzle. Just my two cents.#6: Jane Doe (telly) on Aug 24, 2008
Don't get me wrong...I love a challenge, but I like a cleverer challenge which doesn't involve "plugging in" colors/squares to eliminate (as a machine would)...other than edge logic (some of which sometimes is still "plugging in"). The purest puzzles have one really thinking, without having to resort to the "plugging in" process...i.e. there is a separate logical process that leads to the answer, without methodical "plugging in" over and over.
...or am I all wet...as I might be if this puzzle's designer might decide to wish me into the pic after my comments lol!
I agree JoDeen and Jan#7: Mark Conger (aruba) on Oct 19, 2008
I'm pretty sure I solved it without guessing.#8: Gator (Gator) on Apr 30, 2009 [SPOILER]

I took the liberty of converting Gator's link to an in-line image. I really should find a way for ordinary users to do that.#10: Gator (Gator) on May 7, 2009 [HINT]
OK, here is what I had to do to work forward. If you look at column 18, you either need to fill in R1C18 or R2C18.#11: Byrdie (byrdie) on Sep 18, 2013 [HINT]
If R1C18 is filled in, then R2C18, R1C7, and R1C11 are blanks (others too), which causes R3C7 and R2C11 to be filled in, and then R3C11. Since R3C7 and R3C11 are filled in, then R3C18 is blank. This will make R5C18 and R8C18 filled in and R6C18 a blank.
Likewise, if R2C18 is filled in, then R5C18 and R8C18 will be filled in and R6C18 will be blank.
So either way R5C18 and R8C18 are filled in and R6C18 is a blank.
Once this is figured out, you will have to do some more simple contradiction logic to finish it out completely.
Does any see a more simple way forward than described above?
I couldn't force a wrong result but I couldn't get further than the same solution as Gator without then having to resort to some look ahead.
