Normal sudoku rules apply
Modular Lines: Any set of three adjacent digits along a modular line has three different remainders when divided by 3. (i.e. must come from the groups 147, 258, 369)
Kropki Pairs: For cells separated by a black dot, one value is double the other. Cells separated by a white dot are consecutive. Not all dots are necessarily given.

Not sure I would describe this as approachable but it is very clever, excellent use of modular lines.

I used to think modular lines were just a less interesting variant of entropic lines, but this puzzle convinced me otherwise! I loved how the solve path used uniquely modular properties. Great puzzle!

Beautiful puzzle! Thought I was stumped for a minute there but then saw the way forward. Really nice break-in at the beginning and again in the middle. Thanks for sharing!

A bit tricky to scan in the middle, but lots of interesting interactions in this one :)
