Rules
Normal sudoku rules apply.
The product of the digits along a hollow orange line is equal to 300.
Any three adjacent digits along a teal modular line have different residues modulo 3 (i.e. one digit from {1,4,7}, one from {2,5,8}, and one from {3,6,9}).
Additionally, the total sum of the modular lines is equal to 300.
Solution code: Column 9

Was bracing for some tedious math problem - and pleasantly surprised with an extremely smooth puzzle with surprisingly little intense addition

Wow. Misread the rule, and thought the product of the digits on ALL orange lines was 300. Way too many digits for that…
Trying again now that I reread the Rogers.

The most manly puzzle I've solved XD! I totally agree with Starlight, this one is very approachable, as it only took me 14 minutes, which definitely break my record for a 4-star rated puzzle. Once I got the general idea, nothing tricky at all!

I think if you understand Maths very well this is a lot easier to solve. I was surprised by the 4* rating. It was fun though.
For a non-Mathsy person it'd be hard for sure.

Another fantastic puzzle, thanks!

My idea for the solve path was exactly what was put in a hidden comment. Still I could not easily figure out how to apply that and had a very hard and tormenty solve. Thanks for the challenge!

Brilliant (and pretty hard) puzzle! Thank you:)
