Chaos Construction: Red Team / Blue Team

(Published on 4. May 2024, 06:24 by KNT)

Place the numbers from 0 to 9 exactly once in every row, column, and region. Regions are orthogonally connected and must be located by the solver. Each region belongs to a team, Red or Blue, and exactly five regions are on each team.

A number placed in a cell with an arrow or arrows in a region on Red Team indicates the total number of cells seen in the indicated directions combined, where region borders or the edge of the grid obstruct vision. The clue cell itself is not included in the count. A number placed in a cell with an arrow or arrows in a region on Blue Team indicates the total number of region borders that appear in the indicated directions combined.

For both teams, a region border is defined exactly as when two directly sequential cells in an indicated direction do not belong to the same region. The perimeter of the grid does not count as a region border.

A 6x6 example is provided:

Wow, that took a while!
This ruleset makes for some very interesting logic in the region-building, with the two types of clues interacting in interesting ways.

Then, as is common in KNT Chaos Constructions, the irregular at the end was very tough for me (and the 10x10 grid did not help).

It is such a delicious puzzle. You realise the importance of each when its role is revealed and wonder at the genius of the setter. But really tough for me. Thanks a lot for sharing!

Decided to embark upon this to mark my 1000th solve on LMD and goodness it was a journey. I found the rules pretty intuitive - but just kept having to catch myself from making counting mistakes. I also struggled somewhat quite a bit with the irregular at the end. Overall enjoyed the journey.

Wonderful! The mixed ruleset provides for some really clever deductions and the region building logic is fantastic!

A 5 star CC getting rated in about 10 hours must be some kind of a record?

Fantastic, loved it!

Very cool idea with beautiful execution of it throughout! (even though I had a hard time recovering at the end because I 'broke' it for some reasons)
That R4C7 cell really was a real hero for me there x)
