Rules: Choose six distinct digits from 1 to 9 and divide the grid into six orthogonally connected regions of six cells each. Place the chosen digits so that each row, column, and region contains each digit exactly once.
RSL thermo arrow: The three digits in the pill form a three-digit number, read from left to right, equal to the sum of all digits on the arrow shaft. Region borders divide the shaft into segments of equal sum (a region border that only touches the shaft at a corner does not count as a division). Within each segment, digits increase in the direction of the arrowhead.
Solution code: Row 4 with "/" marking region borders (e.g. 24/6/789)

I missed this puzzle so much (Blue arrow) :)

Very smart construction. I felt the rule about increasing order a bit sloppy. It seems to be very powerful but I didn’t have a need for it until the very end just to resolve disambiguations. However, it does not cancel overall brilliance of the idea. Thank you so much for such a fun puzzle!

After doing lots of arithmetic filling the grid felt quite easy - and miraculous, too! Thank you very much for creating and sharing another incredible masterpiece.

I couldn't find the right path for figuring out the sum, and resorted to elimination. I'm sure there was an easier way that I missed... Filling in the digits once I got the sum was very smooth

Very clever construction. Thanks

Very mathy start, before I saw the pattern of the region sums! Brilliant puzzle and relatively smooth solve path (after the initial deductions) :D

This is a mini composition of two of my earlier puzzles, Blue Arrow (000LYT) and Broken Thermometer (000P06) --- hopefully taking the best of both worlds, with a few bits of fresh logic mixed in. You may still feel some connections to the originals, though.
