For those who like a colouring puzzle, like I do!

Normal Sudoku: Place the digits 1–9 in every row, column, and 3×3 box without repeats.

Modular Lines: Every set of three consecutive digits along a line must contain one digit from each of the following groups: 1/4/7, 2/5/8, and 3/6/9.

Kropki Dots: Cells separated by a white dot contain consecutive digits. Cells separated by a black dot contain digits in a 1:2 ratio.

Not all possible dots are necessarily given.
