Normal sudoku rules apply.

Assign each line a distinct modulus value from 2 to 9. For any digit, x, on a line, the next digit on that line is equivalent to x+1 (modulo N) where N is that line's assigned modulus value, starting from the circled digit.
Different lines have different colours and different associated values. Digits may repeat along a line if allowed by the other rules.
For example: the line with modulus 5 could read 7,8,4,5,1,7,3.
