KNetWalk: Can the "Master" level be solved?
Recently I stumbled across KNetWalk, a quick and simple puzzle game that's good for occupying a spare minute (much like Minesweeper). There are four difficulty levels: Novice, Normal, Expert, and Master. Once you learn what to look for, the first three levels aren't too difficult to solve. But I fired up a few Master levels, and they all looked impossible. There's no help file included with the game, and only a license agreement in /usr/share/doc/knetwalk. I also couldn't find a Web site associated with the game, so no docs online from what I can tell.
Does anyone know if Master is intended to be unsolvable? Or am I just not up to the challenge?
