I remained a long time stuck 2 off and as usual when it's clear that it's optimized and the route must be different, I have it hard to force my mind to reset and build up something new. However, once I did that, I won straight after 3 tries... LOL
The mind reset is the hard step... :D
(sometime in May, 2023) I was stuck 4 off, here, for about a month (since it came out). Today, while trying it's ''pair-level'' (B2), I came back and found 3 variations of a 2 off (130) here, but still can't optimize. It's a great puzzle. I hope to solve it, one day. :)
EDIT (2023, 7th June): I finally managed to find the last 2 steps. These ''burger'' configurations are still so hard for me to figure out. :)
