Once I got rid of the 2 off, I was disappointed because my route was correct all along: It was just about ordering. Idiot me searching for a nice specific trick or a crazy route... Nope. LOL
10 months ago, was 2 off and gave up. Today, I come back and solve it on first try.
I'm sure I have 2 brains, the snail one, huge, covering the clever one emerging only once in a blue moon... LOL
I was stuck 4 off a long while. Today, I came back to the level after a long break and found a 2 off. At first I didn't see out how to cut 2 more. I thought it must be a case of "seems longer, is shorter" and at a certain location, tried something apparently longer, that was the 2 steps saver for the global route. LOL! So typical...
On first try, thanks for logic. This board serves well to remind one of the basic rules: In case of repeating back and forth, minimize the distance... :D
