#172 Ripple Effect – rated hard
Very Nice. I enjoyed that one. It helped me that I had used a similar opening in one of my puzzles as well.
In between the targets, but a bit closer to 10 minutes than to 5 so I don’t think I’ll need to be retaining additional security at the moment. I liked the challenge. While the context was certainly different, the logic reminded me of something I discovered with the habanero Ripple Effect from Puzzle Tokyo. Was that a similar inspiration here as it was with an earlier Yajilin?
About 20 minutes, after restarting from a mistaken conclusion.
