This is a trial of the new ruleset: Sumban line. I estimated it to be 3 or 4 star
Rules:
Normal Sudoku rules apply.
Sumban line (Light Orange): For a Sumban line with a length of N, The individual sums of N-1 groups of adjacent 2 digits on the line form a sequence of consecutive non-repeat digits, in any order. The outlined one is for clarification.
example: a vaild 5 digits on a 5-cell sumban line is 56739 as 5+6=11, 6+7=13, 7+3=10, 3+9=12; 11,13,10,12 form a sequence of consecutive non-repeat digits
Digits cannot repeat on a Sumban line.
Black dot: 2 digits seperated by a black dot must be in 1:2 ratio.
Solution code: Row 9 (rightwards)

Definitly a 4* rating, I had to try a lot, but it's an interesting new constraint.

This is in the 4-5* range. I'm 40 minutes in and have only resolved around 1/3 of the grid. The solve so far has been very grindy.
