Little Deadly Construction
(Published on 21. December 2024, 12:32 by Myxo)
It has been a while since I published a Chaos Construction. I have not enjoyed the setting process back then, but that has changed recently. This one combines Little Killer and Region Sum Lines. Enjoy!
Rules:
Chaos Construction: Divide the grid into orthogonally connected 9-cell regions such that each cell is part of exactly one region. Fill the grid with digits 1-9 such that no digit repeats in any row, column or region.
Region Sum Little Killer: Clues outside the grid indicate the sum of the digits along the diagonal blue line that the arrow points to. Additionally, region borders divide these lines into one or more segments. Each segment within a line must sum to the same total. (Note: A region border that only touches a line at a corner does not divide the line at that corner.)
Solution code: column 8

Smoothest CC ever, which was surprising given the minimal clues ! Thanks :)

Beautiful puzzle, really enjoyed the key deduction for the break-in and then enjoyed the mix between having to use the numbers and the geometry of the regions to finish things off.

Did you invent numbers? Because all of the sums work so perfectly together, mathematically and geometrically, that it’s hard to believe this exists.

Superb construction. Very enjoyable. Satisfying all the way.

It took me an hour and a half but I absolutely loved it. Great job Myxo.

Nice concept and excellent implementation.
"A region border that only touches a line at a corner does not divide the line" should be "[…] does not divide the line *at that corner point*", because the same region border may still divide the same line at some other places.

What a lovely puzzle!

Very nice puzzle !

A very interesting combo. The break-in is nice, and there is a rather interesting moment mid-solve that can lead you astray. But as soon as you get it, it is all very pretty. The way the final regions resolves is also very nice. Thank you for this construction!

Very nice and smooth!
Surprising how this ruleset can force a unique solution with so few clues, but it all comes together so beautifully. I'd say for me, it was a 3 star difficulty, but very, very fun!

Very good fun, flow and balance of tricks and sudoku deductions. Maybe I got a little lucky with always looking at the right places at the right time.

"so little to go on". (Could have been the title as well). Very nice. thanks

There are some very fun moments in this solve.
Had a really good time.
Thanks a lot Myxo.

very nice！I am not very good at CC, so this puzzle may be difficulty 5 for me.

Straight-forward solve path for chaos construction and little killers... Didn't know such thing even exists before solving this puzzle
