Chaos Deconstruction: Position Sums

(Eingestellt am 29. Juni 2022, 16:05 Uhr von KNT)

Place the numbers from 1 to 9 in the grid such that no number repeats in any row or column. Each number belongs to an orthogonally connected region that contains each number from 1 to 9 exactly once. The regions must be located by the solver, and there are 9 total regions that must be located.

A number placed on a cell with an arrow indicates the total number of empty cells in the direction of that arrow. A cell with an arrow must not be empty.

An inner outside clue indicates the sum of the first two numbers seen when looking into the grid from the location of the clue. We call those two numbers A and B. An outer outside clue indicates the sum of the numbers in the Ath and Bth cells when looking into the grid from the location of the clue. If an outer outside clue is present, it guarantees the Ath and Bth cells are nonempty.

If an outside clue is colored, then the summed cells belong to the same region. If an outside clue is not colored, then the summed cells belong to different regions. A question mark may be any positive integer.

Very fun puzzle!
Not too difficult, but a lot of fun logic. Pretty interesting clues that I haven't seen before, but enjoyed. Definitely enjoyed all the weird regions shapes as well.

Very cool!

What a masterful puzzle. Incredibly intricate and well constructed. I broke it the first time, came back to it a week or so later, got quite a long way in before breaking it again. Then I realised my mistake - a rash assumption as usual - and was able to backtrack a little. Thanks KNT.

Auch wieder große Klasse!

Großartig und ausgesprochen kniffelig.
Great and extremely tricky.

What a great puzzle ! Remembered me a puzzle by Jesper I think, but with a hint of KNTesque flavour here and there. Had to remind myself several times that A+B didn't have to be orthogonally adjacent...

Fantastic!

Thank you all for the nice comments! I intend to make more Chaos Deconstructions in the relatively near future :)

It is a very nice puzzle. I have recorded a video on solving this. Here is the link. KNT: if you don't like this, delete the comment and let me know. I will not post again for your future games.

I don't mind at all- in fact I welcome any and all of your solve videos in comments. They are a joy to watch.

Superb! Loved the creative ruleset and the region geometry. Thanks KNT! :)

Very nice... smooth solve the second attempt :-). thanks

Extremely easy puzzle - to make one mistake after another. :D

good puz, my first proper KNT solve. enjoyed a lot <3

Wonderful! So enjoyable to work it out, step by step.

Fixed ANOTHER typo in the example image. Today just isn't my day it seems...

Great puzzle! Very clever clear but narrow solution path.

Had a lot of fun getting to grips with this puzzle, there's a lot going on in there. Thanks! :)

Very nice puzzle! I cannot believe this ruleset, which sounds dumb at first, can create such unique logic!

This is like trying to do Position Sums after getting bonked very hard on the head

Delightful puzzle, very clever and intentional all the way through. Thanks!

Updated rule 2.

@bansalsaab, no an arrow cell cannot be empty.

@dandbdi. the regions themselves must be orthogonally connected (like in a normal chaos construction). There is no restrictions about where they are in relation to each other, as you can see in the example grid.

[1. ..., and regions are orthogonally connected.]
Between each other (the example does not satisfy this), or does it just mean that "a single region consists of orthogonally connected cells"?

Hi KNT, can an arrow cell be empty?
