Ascending From Chaos

(Published on 21. July 2026, 09:29 by sujoyku)

This is the first Chaos Construction puzzle that I have set. I am thanking all testers and wish you joyful solving!

Rules:

- Chaos Construction: Divide the grid into seven orthogonally connected seven-cell regions, and place the digits 1-7 once in each row, column, and region.

- Ascending Starters: A clue outside the grid gives the sum of all continuously adjacent increasing digits up to (and not including) the first digit that decreases in that row or column from the direction of the clue.
Moreover, for each clue the digits contributing to its sum must belong to the same region and the first decreasing digit must belong to a different region.

Here you can solve the puzzle online:

Solve on Sudokupad

Solution code: Row 6 from left to right with the symbol "/" marking borders between regions (for example 12/345/67)

Lovely CC, got easier when I remembered that digits only went up to 7.

**
Thank you, damo_89! Digits only being from 1-7 is definitely crucial here. :)
I am glad that you liked it.
Kind regards, sujoyku

This puzzle was weird in terms of how hard it was.
Brilliant, but very frustrating a the start.
4* just for the breakin.
Maybe it was about getting my mind around the ruleset.

Thank you for your comment, highonlife! I am sorry to hear that you experienced the start of the puzzle as frustrating. As you say, the ruleset needs some getting-used-to. I hope it became more fun for you later on. :)
Kind regards, sujoyku

@wuc if that was possible, the 7 in that column would cause some problems

Very nice first CC puzzle. And an excellent choice for the rules. Low 3* or high 2* in my opinion.
