For me, this level was very hard. A lot harder than some levels of higher categories. I finally got it today, but it was luck as I can't tell - at all - what was different between the route I tried that won now, and all those I tried before.
One year ago, I struggled at 2 off and gave up. Today I came back to it and solve it within a few tries. Call it luck: I decided to give a go to what seems - to me - the less intuitive path possible... And that was the one! LOL
For now 6 off and struggling to see a way to cut. Challenging one for me.
Some weeks later: I had totally forgotten how I reached 100. So I restarted from the scratch and never saw again the 100... Instead, I won! ROFL
