This has tricky color logic and one bit of very hard to find advanced logic.

You can use color and edge logic until all blue is done and all rows from 14-30 are done.

Then I had to look long and hard to find the edge logic on the 6 in c23 (vs the 3 in r9 and 2 in r8):
If 6 goes down to r9 then
- the 3 in r9 must be c22-24
- also the 2 in r8 must be c22-23
That puts a 2 in c22 where there is only a 1 clue, so c23r9 must be white.

Then a lot more line logic.

Edge logic on the 6 in r1 is the last bit of advanced logic.

welcome back to creating again
i have missed your puzzles

Thank you. I'm back to having two bosses again, so little time to spend here.

I made a puzzle about a month ago, but couldn't find the time to tweak it, and didn't feel like fiddling with that one tonight. Maybe next week.

Fun puzzle - very difficult.

excellent solve
nice image too

Found to be logically solvable by Gator.

Very fun to solve. Agreed on the logic you laid out.

I did exactly what you said, w/o reading it! Proud of myself!!!

no looking, great puz, tuff solve, thx Joe

at least I managed to solve this. I thing that it is one of the hardest puzzles I ever done. It can be solved by logic alone and that makes this puzzle one of the nicest.
thanks a lot.

Yikes, that was difficult. I like your description. :-)

Fun solve even though I did have to guess several times.

nice. solved again. pure logic.
