Chaos Construction: Divide the grid into regions, each consisting of nine orthogonally connected cells. Each row, column and region contain the digits 1-9 once each.
Thermo: Digits along a thermometer must increase from the bulb to the tip.
A digit on an arrow shows the number of different regions in the indicated direction, excluding the region containing the arrow.
Solution code: Column 6

Nice one, thanks. Tricky at the end finalising those regions, and I was quite bamboozled at the start, couldn't get my head round the "excluding..." bit.

Wow, I've restarted this 4 times and keep breaking it at the same spot. Must be a nasty trap I keep falling into.

Ah yea it is a bit tricky - I definitely made some mistakes initially when setting it. The most likely reason is that an arrow can see the same region twice and it only counts as 1, e.g. a region could loop around another one. Good luck :)

Wow, spectacular logical flow! The construction certainly threw me for a loop a few times, but it was very cleverly done!

Beautiful and fun puzzle with some devious traps, which fooled me! Thank you

Fun puzzle, with some tricky region-building esp towards the endgame. Thanks for sharing, @ Belamis :).

Awesome. Very smooth. Had some trouble finding the regions near the end. There it was 4* for sure. Great fun puzzle thx.
