When I struggle with a 2 off, I have a few tricks to help me unstuck the situation. In this case, I applied one of them and it worked straight on the next try. I do love that trick... :D
I like that watching ahead allows for a win on first try. Observation helps *********************************************************************************************.
For me, this level is a proof that I cannot intuitively select the correct route on first try. I dont "see" what one will be shortest. I need to test them.
