Chaos Construction : Wrogn

(Published on 8. June 2022, 20:59 by lerroyy)

Rules:

Place the digits 1 to 9 once in every region, row and column. The regions must be found.

Construction part: Cells in a cage may not all be part of the same Region. On any kind of line (including thermo), a straight orthogonal segment can not have all its cells in the same region. A straight diagonal segment must have all its cells in the same region. Cells connected by a dot, X or V must be in the same region.

Sudoku part (same rules as "Just wrogn enough" apart for killer cage rule): In cages, digits must not sum to the clue in the top left corner. Digits may repeat in cages if allowed by other rules. Digits separated by white dots can't be consecutive. Digits separated by black dots can't have a 1:2 ratio. Digits separated by a V can’t sum to 5. Along the thermometer is a bulb (it is not the current one and that has to be found), digits must increase from that bulb to the extremities and may not repeat. Digits along a renban may not repeat and must not form a set of consecutive digits. Digits in a square are not even. Digits in a circle are not odd. Digits in a min cell have to be bigger than ALL the orthogonally adjacent cells. Digits in a max cell have to be smaller than ALL the orthogonally adjacent cells.

You can try my 6x6 puzzle first if you want to try something a easier, and get familiar with the rules.

That's a really good puzzle. I need to pay attention to every detail. I missed a detail due to my own negligence, resulting in being stuck for dozens of minutes

What I liked about this puzzle, is how every clue is so useful at every stage of the solve ;)
Some very tricky moments for me here, but I got through !! Thanks !

Fantastic puzzle!

Easy start, then it became somewhat tricky but no less interesting, (almost) every clue really works in a magical way, particularly like how the thermos were forced and then the regions at the end :)

Very nice implementation of Wrogn logic into C.C.! Loved every single thermo in the puzzle.

Thanks for the nice comments! Glad to see you enjoyed the puzzle!

That was BEAUTIFUL. Really cool logic involved in this one, took me a while to solve, and a couple restarts.

This was very hard for me, but the first half of the digit placement logic was a lot of fun

Had an abortive attempt because I was trying to make the renban work, which is wrogn, because the renban should instead not work, which is rihgt. Brutal puzzle, thank you for setting.

Phew, that definitely earned its not less than 5 stars. Took me a couple of sessions to work through it, had to keep giving the brain a break. Brilliant puzzle, thanks Lerroyy!

Superb! Just that some clues are totally useless at all.

Thanks glad you liked it! Some clues are just used for the construction part and are useless in the sudoku part like the ratio dot in R8C45

Very enjoyable!

Thank you for the nice comments @Gnosis66, @RJBlarmo and @DiMono!

Very enjoyable. At first it seemed like the rules about the lines would make this puzzle easier than your previous one. Not true. These Wrogn puzzles are becoming some of my favorites.

Very challenging and extremely rewarding. Enjoyed the mix of clues being used for region defining purposes and numerical purposes.

This is an incredibly difficult puzzle, and a very satisfying solve. First Wrogn CC I'm aware of.
