Incredible puzzle with lots of great deductions all the way through ! Had to give it a rest because I got stuck in the middle. I was trying too much to get the regions early on, then realized I had to do the construction and the solving simultaneously at some point. Very satisfied with this solve in the end. Thanks.

I tripped myself up with a wrong deduction early, but once I identified that and corrected for it everything went pretty smoothly. Wonderful puzzle!

Very nice indeed! Especially the row 789 stuff maybe a 4.5 difficulty :)

Very nice puzzle! Although I disagree with 5 difficulty as it took me 43 minutes. The geometry used in the puzzle is mindblowing!
