I got here quickly enough, then stumbled hard, trying several unlucky guesses that were neither obviously wrong nor led to an obvious solution.  How do you wizards finish quickly from here?  Thanks.

There's a simple Highlander in the top left but I didn't see that.

I imagined lines in and out of the top-right corner, and noted that it sent three threads into the top left. And so does making that same connection concavely.

I did some reading in the top right like Puzzlelover did, but it turns out if you use the Highlander mentioned above first, you get a second occurrence of the same pattern that solves the whole thing without any reading, making it a viable sub-minute puzzle. Gotta get better at spotting those.

This bit of the puzzle is the only reason that it got rated a "hard", I think. Certainly the first part was very easy!

From here, I could just see the solution - no conscious logic involved at all. I like it when that happens, as it saves a lot of trial and error or brainwork, but it doesn't happen very often.

Seems this has gone from "How do you do it without guessing" to 57 seconds, the new record for Thursday. So how did you do it, Oyvind?

Well, line counting helped me a bit. The column with the 2s has odd number of lines, so I knew only one horizontal line would fit (three was impossible). Because of that I saw that the bottom line (of the two 2s) did not make any sense. This was my next step:

Then I saw that if I continued horizontally with the middle line (between the 2s) the semi-loop to the right didn't make it.

Then it was easy
