I keep running into trouble with this one. I have started it from scratch a number of time now. I never run out of what I perceive to be forced moves, but I always end up a conflict where no move can satisfy the required condition. The left 2/3rds always come out fine, but even if I only do the right 1/3rd, I run into a conflict. Are you SURE this puzzle is consistent? Any chance you could share the solution to this one with me? I give up. I promise not to share. I am a retired (geriatric) mudder.
