The line is a German Whispers -- digits must have a difference of 5 or more.
Black dots have a ratio of 1 to 2. White dots are consecutive. Not all dots are given.
Japanese Sum Sudoku rules apply. Numbers outside the grid give the sum of shaded areas. There must be at least one unshaded cell between consecutive shaded cells.
Solution code: Row 1 Column 5

I forgot about a few deductions on the GW lines, and struggled to find the opening. But once I stopped being stupid, the logic flowed nicely.

Penpa link redone. Hopefully it works right now! :)

Very nice! For some reason the solution check in the Penpa+ link doesn't work when cells are shaded.
I gave up on penpa shading when the person who created penpa asked me "why would someone want to put a number in a shaded cell" -- I asked him to allow other colors, but he only allowed dark black and dark grey for shading. Doesn't quite work with my multicolor Jap Sum Sudokus :P

What fun. First time doing German Whispers and Japanese sums, and that was a lovely intro.

Ew, that joke is in pretty poor taste, henrypijames.

A good intro to both German Whispers and Japanese Sums. But add something Italian, and it could become truly evil. ;)

I have nothing to add to my displayed comment. Very fun!
