Normal sudoku rules apply.
Digits on the arrow must sum to the total in the 2-digit circle (read from top to bottom).
Digits on therometers must ascend from the bulb end.
Palindromic lines have the same digits forwards and backwards. Example: 747 or 99.
Solid Kropki dots indicate a ratio of 2 between those cells. Example: 2 and 4, or 6 and 3.
Hollow Kropki dots indicate a gap of 1 between those cells. Example: 2 and 3, or 8 and 7.
Solution code: Solution code: first row, last row.

Are all Kropki dots included? (i.e. can we have 3 next to 4 without a dot?)
@hypercrypt Sorry for the late reply. No, not all dots are included. There is no negative constraint.

If you want more visibility for solves, you may want to update the tags to include suduko- I came across this puzzle via the "no sudukos" query
