Some Kind of Chaos
(Published on 24. May 2024, 09:25 by marty_sears)
Thanks again to BlackjackFitz for inventing the marvellous Somedoku format. I am finding it so fun and flexible to set with!
Rules:
- SOMEDOKU: Fill the grid with the digits 1-9. Each row N and column N contain exactly N distinct digits, with the rest of the row / column being filled with repeats.
- CHAOS CONSTRUCTION: Divide the grid into 9 regions, each containing 9 orthogonally connected cells. The finished pattern of regions will have 180 degree rotational symmetry.
- CIRCLES: The digit in a circle indicates how many distinct digits appear in its region. Eg: A 6 in a circle indicates that the region includes 6 distinct digits (and 3 repeats.) No two circles contain the same digit.
- REGION SUM LINES: Region borders divide blue lines into segments, each of which have the same sum. Each blue line must cross at least one region border.
Please leave a comment if you enjoy :)
Solution code: Column 9 reading downwards

Another amazing puzzle, loved the deductions in it, and how it looks daunting but actually gives way reasonably easily. The 180 degree symmetry is a really fun rule to combine with this kind of construction.

Wow, I've solved a 5⭐ puzzle for the first time ever! And it only took me 3½ hours...
Difficult, but fair. Everything was deducible ... eventually.

Fantastic puzzle! I on the other hand made so many mistakes, I don't think you could call what I did for a solve. Got there in the end though :)

...and this is why we call him 'Mad Marty'.

I must have spent half of my solve waiting for it to break, revealing a bad deduction I made an hour ago. The suspense until the last digit made for an immensely satisfying finish. So incredible!

Wonderful. CC + somedoku clearly are a great combo

Smooth and enjoyable, especially once you remember the symmetry rule after 30 minutes :D

Wow, brilliant! It was quite a journey finding the symmetry in the chaos

Brilliant puzzle, the symmetry aspect to the region building was really fun to figure out!

Lovely puzzle! I was a bit confused by the wording on the "somedoku" rule, but it was only my own misconceptions.
