I struggled solving my 2 off. For me, there are two types of 2 off: those solved by a specific trick and those purely about correctly routing through. This level is of the 2nd type, and for me more difficult because intuition doesn't help much. It's more about testing alternatives until one works.
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
