Chaos Construction: Aquarium (2)
(Published on 23. June 2022, 01:08 by KNT)
Every cell in the grid is either 'air' or 'water'. Within each region, each row of cells is either all air or all water, and all air cells must be above all water cells. A number outside the grid indicates the total number of water cells in the indicated row or column.
If a cell with arrows is 'air', the number placed in that cell indicates the total number of water cells in the indicated directions combined. Likewise, if a cell with arrows is 'water', the number placed in that cell indicates the total number of air cells in the indicated directions combined.
Solution code: The air cells in the bottom 4 rows, left to right, top to bottom.

I feel like this puzzle perfectly captures the identities of a setter like KNT here - a gorgeous and incredible solve path with also a very consistent difficulty from start to finish.
Almost went insane at certain points where I thought I broke the puzzle but no, it's mostly poor scanning by me. Also how did you manage to make the ending come together like that, I had no idea xD

I wasn't able to solve this back then, but now it was quite smooth. Awesome!

Very tough puzzle indeed. Consistently difficult, all the way until the end.
Very enjoyable, with lots of interesting deductions throughout.

Absolutely brilliant, but brutally difficult.

Great puzzle ! A much harder solve than the 7x7 version that I solved a few weeks back. This had really tricky deductions in it. What amazed me the most was the fact that some cells had to have the same value independantly of their nature (air or water). Thanks again KNT !

I'm glad I was undeterred by the difficulty warning and did this puzzle cold - without the 7×7 warm-up. It was more fun this way, and only 4½ difficulty for me regardless.

Brutal, and I was 13 minutes too slow... RIP.

Excellent puzzle. A solid 5 star for difficulty. Every little deduction required some effort. The irregular sudoku at the end of the solution was also challenging. One of your best puzzles, in my opinion. I'm looking forward to Simon's video :)

Really fun challenge! Very easy to make a mistake on this and I had to restart a few times. Extremely satisfying when everything finally falls into place at the end.

Congratulations on the solve! I'm glad you persevered even after having to restart the puzzle several times.
