Chat, we have another banger with only 3 rules:
1. Normal Sudoku rules apply.
2. ANTI-KNIGHT, meaning that no digits a Chess knight's move away from each other can be the same. e.g. R1C2 ≠ R2C4.
3. Modular Lines are such that three adjacent digits on a line must all be of different respective values modulo 3.
I made a mistake in calling these entropic lines when they are in fact modular lines. Whoops

I think a little tricky for a one star rating, but very nice puzzle!

I was going to make the same point as @Slumped_5. Don't think I need to bother now :)

It'd be better to change the color of the lines as well. For a person who has puzzles with entropic and modular lines, it's difficult to visualise a peach line as a modular line.

Update to the description of the lines

rules are wrong, these are modular lines not entropic.

Quite approachable. But as mayiyang said, definitely modular not entropic!

Neat and brilliant! The solve is quite smooth for me.
But should these lines be called modular lines? Entropic lines seem to be those along which any set of three sequential cells containing a low digit (1,2,3), middle digit (4,5,6) and high digit (7,8,9).
