The puzzles posted here need to follow the standard rating system that Børge described, not use some other rating system. The point is, ton, that the puzzle you posted, while very much appreciated, doesn't match the level of difficulty expected for this forum. |

I finished this puzzle today. While the solving path wasn't as quick as I'd expected based on Børge's feedback, once I made the first pass through the four outer grids, the puzzle quickly fell apart into singles. I agree with Børge--this puzzle doesn't qualify for Apprentice level. However, after beating my head against tarek's Bank Holiday 0808 Kazaguruma #3 (AGAIN, for the 3rd or 4th time), I was ready for an easier puzzle. |
