Balanced Chaos
(Published on 29. November 2022, 16:24 by fritzdis)
Chaos construction rules apply. Divide the grid into 9 orthogonally connected regions with 9 cells each. Fill every row, column, and region with the digits 1-9 once each. A few region border segments are already given.
Blue lines are region sum lines. For a given line, the region borders separate the line into two or more segments with equal sums. Distinct segments within the same region are not summed together.
Solution code: 18-digit code: row 8 + column 9

Great puzzle with some algebra, which I had to do on paper, in the end! Thank you.

This puzzle fully deserves its 5* rating for difficulty, yet solves elegantly: what a construction!

Next Level Hard But Also One Of My Favorites.
The solution was:
….…many days if struggles…..and finally:
XA=BF 7+6=1+3 or 5+3=2+6
So the results are:
X=5/A=3/B=2/F=6/T=4/G=7/Q=8/K=1
Figure this one ot fior yourselves!
And As A Reward I Get To Watch How Simon Solves This (Video) And If He Solved It In The Same Way…..:-)

Came in here expecting to do region building, spent all the time doing math :P
Wonderful puzzle!

What an incredible puzzle ! It has it all ! I haven't seen the CTC video yet, but I was smiling inside myself when I got to the point where you need to use "the secret". I could almost picture Simon pausing for a brief moment at that step, raising his index, and telling something like "oh, that is just utterly clever, and this is because of the secret, now..."
Now I'll share another secret with you : I loved this puzzle ! Thanks.

Absolutely magnificent!
I love how the puzzle kept evolving throughout the solve, and with every stage adding new types of interesting logic to explore. It was a long solve, and I enjoyed every minute of it. Didn't get tired at all!
Thanks a lot, @fritzdis. Highly recommended!

Excellent puzzle! Very clever use of the region sum lines, and a nice surprise at the end :-)

I loved this puzzle and was surprised by the difficulty (it said 4* when I started) but somehow made it through. Definitely 5 stars but one of the best 5* puzzles I've solved.

Minor rules clarification per feedback from @henrypijames
on 30. November 2022, 06:58 by henrypijames
If a line *is* allowed to be within a single region, that should be stated so in the rules as well. My point is, when it comes to rules, it's always better to be explicit.

very nice with refreshing new logic. thanks.

Some really nice novel logic. Recommend for CtC.
Rules need to specify that no line may be entirely within one region.
