This is a Numberlink puzzle.
I feel a bit guilty for posting that solving guide now. The best Numberlinks in my experience are the ones with the least straightforward solution. So when I’m constructing these I’m always trying to play games with the tricks I described in that post. I feel like a salesman that just convinced you to buy a product that does nothing but punch you in the face.
On thinking about it more though, a lot of my puzzles are a punch in the face. I guess you guys like it.
