Level 2-16 'neutrinos'

I can only do 2-16 in 21 moves (about 5 different ways). Perfect says 20. Any ideas?

Hey there, Thatnowfeeling, and welcome to the forums.

I took a peek at the perfect way of doing that level (after trying a couple times and also getting 21, like you), and yes, indeed, it is possible in just 20 moves.

I'm not sure what a good hint is, but I will mention this surprising fact: you only change one of the neutrinos. Ran against my instinct of changing two of them.

Thanks for the reply.

That's helpful. I'll persevere with the 'one change' permutations..have also found several of those that produce a 21 move solution, so ...must...slice...one...move...off...

There are only somewhere around (3 particles * ~3 directions-to-move-per-particle-per-turn)^20 turns possible chains of moves you need to check. I'm sure that's a small number? ;)
