Oooh, very nice! Thank you for the Christmas present! This will be a nice break from a couple of your Clueless Specials that I'm stuck on (again)! |

I FINALLY finished the Novice edition of this puzzle. Very nice! It wasn't particularly difficult--just time-consuming (as most gattai are). In addition, I didn't get much time to work on it over the Christmas holiday (seeing as how I'm the one who gets to make Christmas dinner, do all the baking, wrap all the gifts, etc.). I think I'll give the Apprentice edition a try next. Then maybe I'll wander on back to those Clueless puzzles I'm stuck on. |

Since all six levels of the puzzle have the same solution, you might find the Apprentice level a bit too easy after having solved the Novice level. The Journeyman level should be a great challenge however.

FINALLY! I got the Journeyman edition completed! I had a slow afternoon today, and high winds (gusts to 65mph) were keeping the Internet connection mostly out of commission, so I had JSudoku help me locate a hidden single I'd missed (in addition to the one you pointed out). Then I had to shut down all of the computers (the wind had knocked our electrical transformer almost completely off the pole, and the electric company had to shut everything down for a half hour or so to fix it). Since I couldn't fix dinner, do laundry, or anything else useful until the power was back on, I made good use of the time and finished off the puzzle. I think the Master edition is a little beyond my skills right now, but I may revisit it when I get up to skyscrapers. |
