It took me a while to find a genre to satisfactorily apply the number 9 to. After going through a bunch of puzzle tests and puzzle sites I stumbled across Anglers. I've always liked Anglers puzzles, so it seemed like a good type. It worked out well. The puzzle isn't too hard.
The digits on the outside represent anglers. Each angler catches one fish. The digit indicates the length of their line. The lines run by connecting the centers of cells horizontally and vertically. They don't touch or cross eachother.
