line/color logic gets all but the lower left corner (and the 2 black pixels that make up the pedal)#2: Teresa K (fasstar) on Sep 26, 2011
then "simple" edge logic on the 5 clue in r20 gets you a dot in c11 followed by "extended" edge logic on that same 5 clue (2 move look ahead) gets you one more dot at c10 which then lets you solve this out with line logic
nice solve
no guessing
Nice puzzle, Brian. Tricky logic, but no guessing. Good way to destress.#3: Aldege Cholette (aldege) on Sep 26, 2011 [SPOILER]

Found to be logically solvable by gator.#6: Gator (gator) on Sep 26, 2011 [HINT]
Nice solve.#7: Brian Bellis (mootpoint) on Sep 26, 2011 [SPOILER]
I believe it is technically a 3-move look ahead, but it is possible to figure out that R20C10 is a dot in other ways (involves some affirmation logic). I'm not going to detail it out though unless someone wants me to as I think it is easier to "see" the 3-move look ahead.

by placing a black pixel in r20c10 (via edge logic) you can fill in black pixels in r20c6-10, r19c6,8-10, and r18c10 (with their respective dots above each of those) and a dot in r19c7, and r19c11#9: Trish217 (Trish217) on Sep 27, 2011
first move look ahead is then placing a black pixel in r18c11
second move look ahead is seeing that a black can not be placed in r17c11 (due to r17 being invalid)
you could technically even count what i described in my "second move look ahead" paragraph as part of the first move look ahead step, seeing as you would be forced to place a black pixel in r17c11 when you placed the black pixel in r18c11 (since that is directly related to that step)
At one point i thought it was architect's tools.#10: Roland Spindler (Mikesch) on Apr 17, 2012
I don't know what it is with this puzzle, but I messed up twice solving it. At least the second time I was able to salvage most of the result, so I could finally solve it.#11: Brian Bellis (mootpoint) on Apr 17, 2012
I have puzzles that may just live permanently in my saved file.#12: Norma Dee (norm0908) on Oct 29, 2016
I have quite a few sitting in my saved file. But this won't be one of them. Good one.#13: BlackCat (BlackCat) on Oct 29, 2016
Wow. That was tricky to see until I finished it. Did have to guess once. Nice perspective.
