A Powerful Duo (Entropy, Anti-Knight)
(Published on 16. May 2023, 09:08 by Mad-Tyas)
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.
Ratio Dots: Digits in cells connected by a black dot are in a 1:2 ratio. Not all possible dots are necessarily given.
Anti-Knight: Cells separated by a knight's move (in chess) may not contain the same digit.
Entropy: The low digits (1, 2, 3), middle digits (4, 5, 6) and high digits (7, 8, 9) are defined as three different groups. In the finished grid each 2x2 box has to contain at least one digit of each group.
Have fun solving!
Solution code: Row 9 followed by column 9 (18 digits)

Tough opening but after that it flowed incredibly smoothly

This was very hard for me but somehow managed to solve it. Thanks a lot for sharing.

Ich sehe es schon kommen: Mad-Tyas wird irgendwann ein Entropiesudoku mit lediglich einem weißen Kropkipunkt in Box 4 veröffentlichen ...
I can see it coming: One day, Mad-Tyas will publish an entropy sudoku with just one white kropki dot in box 4 ...
