Budowa (Chaos Construction, Kreska)
(Eingestellt am 4. Januar 2026, 12:00 Uhr von Crusader175)
Rules:
Chaos Construction: Divide the grid into regions of 9 orthogonally connected cells each, such that every cell is part of exactly one region. Place the digits 1-9 exactly once in each row, column and region.
Kreska: Adjacent digits along a line must either be consecutive and belong to a different region or have a 1:2 ratio and belong to the same region. If 1 and 2 are adjacent along a line, they can satisfy either condition.

Beautiful puzzle, first 6 rows were excellent fun, the rest resolved like a typical chaos construction. Very fun ruleset, not too tough once you learn the "trick"

Wow! This was one of my favourites ever.

Lovely! Very easy to make a mistake especially at the beginning where the regions seem so unconstrained, but after a certain point the chaos construction just works its magic and it is easy slopes right to the bottom.

4* break in but then i agree the rest flows so smoothly and satisfyingly at around 2* toughness

Phenomenal puzzle with fresh, very fun logic. Thanks!

Loved this puzzle! I loved how the two rulesets interact with each other so smoothly. Though I wonder what is the intended way to figure out the four cell Kreska, since I solved it in kind of a clunky way.

Staring at this puzzle for a while before the rules kick in. Then it solves rather smooth, surprisingly so in the clueless bottom rows as well. Bravo. Thanks
Reply: I try to make sure that the endgame is smooth, so that's glad to hear. Thanks marcmees!

Great puzzle! Tough ruleset, but very rewarding solve. Thanks
Reply: Took me a some time too when I solve my first kreska. Thank you Snookerfan!

Just for clarification, e.g. R1C1, R1C2 and R1C3 belonging to the same line, should R1C1 v.s. R1C2 and R1C2 v.s. R1C3 follow the same Kreska rule? I.e. is it allowed that R1C1 and R1C2 are consecutive and belong to different region, while R1C2 and R1C3 have 1:2 ratio and belong to the same region? Thanks!
Reply: Yes it's allowed. So you need to determined the condition for each adjacent digits.

Wonderful setting! A couple of tricky bits at first, but then it resolved rather smoothly till the end and I was in awe of how it all came together towards the end too, quite a crazy achievement there xD
Reply: Thank you for the test solve help Playmaker!
