Normal sudoku rules apply.
Along the lines, white dots separate consecutive digits, black dots separate digits where one is double the other (not all such dots are shown).
Digits separated by an X sum to 10 (not all X’s are shown).

At first glance it looks like there isn’t enough information. That given digit does all the work. Very nice as it comes together

I don‘t know if it was intended or not, but I did not need several of the white dots for my solve.
