Thanks h3lix – great puzzle. I especially liked having to discover and then apply the new techniques necessary to solve it.

Like wellbeback said, great one. But since you’ve provided the solution pic, and I don’t have the energy for a walkthrough, there’s not much I can post here. 🙄 So next time I suggest you to keep the solution unpublished for a few days.

That would be a good idea. I was modeling my posts after djape’s since he posts solutions along with the puzzles.

Thanks for the feedback!

A walkthrough and/or some of those new techniques would be great. Only way to learn!

I take an opposite view to udosuk – I like the solution together with the puzzle so I do not waste time chasing ghosts (mistakes…)and getting frustrated

David has a good point, and I suppose it would be a bigger inconvenience for someone who is stuck or made a mistake somewhere to not have the solution than for the solution to be available.

However, it would be fun to have a competitive aspect to the saturday specials 😈

Charmommom, I have posted the beginning of a visual walkthrough here:

Okay, points taken. I agree the solution might need to be there…

My competitiveness is sometimes unreasonably high, once in a while in four years. 😉

I guess I’ll leave the solution on then until I can think of a prize and a puzzle that can’t be solved with any known solvers, like mike’s variant.

more non consecutives

Just finished this on a plane after working on it for months on and off. Really great puzzle; I could tell I was solving it the way you intended.
