I basically employed the same method as Jan. The red & blue solved quickly. Between a big hint from the title and looking at plausible cominations (either-or logic), I got it on the first try.#5: Jan Wolter (jan) on Jan 13, 2009
It's not a terrible image but one would think that some effort would've been applied (with the help of the checker) to make it more easily solvable.
I'm pretty sure Shay doesn't test solve his(?) puzzles. Some turn out to be fun to solve, but that's pretty much by accident. I wish he would take the extra step ti refine his puzzles a bit more.#6: K Chouinard (codenumerator) on Jan 13, 2009
This one is kind of interesting though. It feels like there ought to be a way to logically solve it. The solution is unique. But I can't quite find a way.
I got it on the first try by just guessing and I am usually a bad guesser. Jan's logic seems to be just a step away from a solution.#7: Twillis (twillis) on Jan 13, 2009
I followed Jan's logic and it seems very good. I think putting a green in the 10th row, 3rd column leads to a relatively quick contradiction after a few steps, so it must be white, and then you can finish the bottom row. Then a green in 9th row, 8th column also leads to a quick contradiction [it would force position (8th,8th) to be green and then positions (7,8) and (7,9) are white, but then there is not enough room for the greens in the 7th column], so it must be white.
Then with a green in 6th row, 8th column, you can finish the 6th row, and regular simple logic should bring it home.
It weird, I could have sworn I solved this without guessing, but now I'm not sure. Maybe I did use the "look ahead" sort of logic discussed above.#8: m2 (mercymercy) on Jan 23, 2009
Or maybe I was guessing and only thought I was being logical.
I guessed but isn't it double smile logic? or perhaps triple.#9: Teresa K (fasstar) on Jan 25, 2009
I went as far as I could with regular logic, then just used "Shay logic" and solved it rather quickly.#10: Web Paint-By-Number Robot (webpbn) on Mar 5, 2009
Found to be logically solvable by jan.#11: Jan Wolter (jan) on Mar 5, 2009
This puzzle has been revised and is now black and white.#12: Meg Smith (Mamadragonfreak) on Mar 5, 2009 [HINT]
Curiously, it became logically solvable when that change was made.

Found to be solvable with moderate lookahead by jan.#20: Jan Wolter (jan) on May 11, 2013
Note that there have been multiple versions of this puzzle, so some of the earlier comments may have referred to the older version. But I'm convinced by David.#21: Joe (infrapinklizzard) on May 11, 2013 [HINT]

I temproarily made the color version of this puzzle to try it out. Tricky.#23: Andrew Schultz (blurglecruncheon) on Oct 9, 2021 [HINT]
