This puzzle was made for Scojo's weekly prompt. The prompt was "Entropy Lines, Modular Lines, and Anti-Diagonal." I decided to make it an ambiguity puzzle as well for fun! I hope you enjoy!
Also, thanks again to gdc for a bit of help with the cosmetics!
Rules
Normal sudoku rules apply.
Grey lines in the grid will be either an entropy line, or a modular line as determined by the solver. The long line that goes through the centre of the grid (r5c5) will change its line type at r5c5, indicated by the circle. (r5c5 will be a valid digit for both lines in its position)
Entropy Lines: Every set of 3 adjacent digits along an entropy line must contain a low digit {1,2,3}, a middle digit {4,5,6}, and a high digit {7,8,9}.
Modular Lines: Every set of 3 adjacent digits on a modular line must contain a digit from each of the mod3 subsets of {1,4,7}, {2,5,8}, and {3,6,9}.
Anti-Diagonal: Each of the main diagonals (indicated with dashed lines) must consist of only 3 unique digits. These 3 digits will appear on the dashed line in each box it passes through.
Digits separated by a white dot are consecutive.
Digits separated by a black dot are in a 1:2 ratio.
Not all possible dots are necessarily given.

Beautiful puzzle! Quite hard at a certain point, but great fun. I believe that I didn't use the top right line. Thank you

Lovely looking puzzle, and I have not seen an anti-diagonal before - I must try that out! Thanks for setting.

Very aesthetically pleasing - I think I did use all the kropki dots though and that they weren't just there for aesthetics, which only enhances the pleasure!
