Beautiful image! (though I'd really prefer it to be a bit smaller, so as to fit into single screen)#2: derby (Derby) on Dec 25, 2024
And oh boy, this took me quite some time and a lot of concentration to finish. I solved this without real guessing, but on two occasions I had to invalidate seemingly obvious dead-ends via deep lookahead. Still, I can only hope I didn't make any errors in logic.
Thanks for your comments. I feel the puzzle can be done without guessing, although sometimes you have to fight for every pixel.#3: Philip (Philip) on Jan 19, 2025
I think I only used moderate lookahead, with lots of very tricky color logic. Very difficult, but rewarding solve!#4: LoloJean (LoloJean) on Feb 3, 2025
I definitely had to look more steps ahead than I could keep in my head at once, but that might have been due to missing easier paths forward.#5: LoloJean (LoloJean) on Feb 3, 2025
Image is well worth it though#6: derby (Derby) on Feb 28, 2025
Thank you for your comments.#7: Kerri Kemp (kerri_kemp) on Jun 12, 2025
Was way too hard for me. Lots of guessing and cheating for me to finally solve it. Sorry, but that makes for a rather unenjoyable puzzle in my books. But I did stick to it to get it out.#8: derby (Derby) on Sep 24, 2025
But I do appreciate you posting this for us to solve. It's not easy producing pics for us to complete. So thank you Derby for that.
Okay.i think it is solveable and if you keep trying new puzzles you will see new tricks to solve them. I only create difficult puzzles because that is the type I like to do.
