Rules:
Sudoku: Fill every row, column and marked 3x3 box with the digits 1-9.
Thermometer: Digits along a thermometer have to strictly increase from the bulb to the tip.
Entropy: Each 2x2 box in the grid has to contain a low digit (1, 2, 3), a middle digit (4, 5, 6) and a high digit (7, 8, 9).
Have fun solving!
Solution code: Row 1 (9 digits)

What a lovely puzzle. I found it a bit tougher than 3* but maybe that’s me not being very experienced in entropy puzzles.
