This is my first published puzzle! It is somewhat inspired by MD88Keys anti-knight/anti-king puzzles.
Normal Sudoku rules apply: place the digits 1-9 once each in each row, column and box.
Digits along a thermometer must increase from the bulb to the tip.
Cells a (chess) knight’s move away from each other cannot contain the same digit.
Cells a (chess) king’s move away from each other cannot contain the same digit.
I really hope you have fun solving this one!

Maybe it's just me, but I don't understand what the "solution code" is.

beautiful demonstration of the POWER of this constraint.
all you need is a bit of snyder notation to get 1-5, and then colouring for 6-9, so relatively easy.
