[Eng] Average Arrows Sudoku with Thermometers, by Philipp Blume

Average Arrows Sudoku:
Standard Sudoku rules are in effect, i.e., every row, column, and 3x3 box must contain the digits 1-9 exactly once each.

Digits in circles are the arithmetic mean of the digits along each of the corresponding arrows. Digits may repeat along an arrow as long as they don't violate Sudoku rules.

Digits along each of the two thermometers must strictly increase, starting at the bulb.

The fascinating thing about average arrows is that a 'pure' average arrows puzzle will always have at least 2 solutions: in solution b, every digit x of solution a is replaced by 10 - x. Only the thermo(s) can disambiguate the grid (or a given, or some other constraint besides an average arrow).
