This is my first sudoku puzzle construction, having been inspired into giving it a go by some of the wonderful puzzles I've enjoyed from this community. Please let me know if you enjoy it!
Rules
Normal sudoku rules apply.
XV: Digits in cells connected by an X must sum to 10. Digits in cells connected by a V must sum to 5. Not all possible Xs or Vs are given.
PALINDROMES: Digits on grey lines read the same forwards and backwards, eg 1-2-3-3-2-1.
MOD-3 LINES: Every set of three consecutive digits on a teal line contains one digit each from the sets {147}
, {258}
, and {369}
ENTROPIC LINES: Every set of three consecutive digits on a peach line contains one digit each from the sets {123}
, {456}
, and {789}
KROPKI DOTS: In cells connected by a black dot, one digit must be exactly double the other. Not all possible dots are given. NB: Dots appear white when using dark mode. All dots in this puzzle are 'black' dots.
Play
Lösungscode: The digits in row 2 from left to right.

almost GAS - thus difficulty 1.
advice for beginners:
1) KNOW the patterns of the variants in play.
2) ALWAYS follow the path of least resistance.
3) FOCUS on basic sudoku.
and specifically, this is NOT a colouring puzzle. the red flag is that TWO TYPES of colouring would be required, and that violates two of the rules above.

I found the later half of this puzzle quite a bit more challenging that the first. I imagine I probably missed some basic sudoku but for me a 3 star.
Edit: I have just watched a solve, and yes I missed one very obvious step for basically the whole puzzle but why do things the easy way? :)

Added link to more accessible version in the puzzle description. Apologies that the original puzzle isn't as usable as it should be.

Can anyone help?! I am colorblind and differentiating the teal and gray lines is impossible for me!

sshrpe: I'm so sorry the lines are hard to see. I had worried a little about that, but I thought maybe by using the default colours in the tool I was using, it might be OK. I've just had a play with the settings to try to make a colourblind-friendly version, where lines have stronger colours, different thicknesses, and are marked with letters. You can try it here and let me know if it works for you: https://sudokupad.app/bclmerl0rl

Very smooth with interesting deductions all the way to the end! I loved the interactions with the mod3 and entropic lines being symmetrical. This is a beautiful first puzzle, great work!
(also the longer code only adds maybe 5 seconds, not even an inconvenience. there’s a couple karens that roam the comments, don’t take them to heart lol)

Thanks very much for the feedback. I’ve shortened the code to make it easier to enter. It’s only my first puzzle, so I’m learning a lot as I go. Appreciate the kind words! :)

Please, for the love God, only use 9 digit solution codes. This is hostile for mobile users, and you made a second error, as you say there is a space required but there isn't.
