Normal Sudoku rules apply.
Killer cages, indicated by dotted lines, cannot have repeated digits and the digits in the cage sum to the total if shown in the top-left corner.
Box borders divide the blue Region Sum line into segments with the same sum. Distinct segments of the line within the same box count as separate sums to the same value.
Digits joined by a white dot are consecutive.
Not all dots are given.

I think it would be helpful to clarify that the RSL in box 4 is one line passing through 7 squares, rather than two lines passing through 5 and 3.
Other than that, fun puzzle!

pagedo: @Plok - The Region Sum rule about distinct segments is there to clarify the Box 4 line. Boxes 5 and 6 each have two distinct segments that sum separately to the same value. There are no distinct segments in Box 4, so all the 7 cells on the line sum to a single value whch is the same as the 2 sum values of Boxes 1 and 7.

Following the rules does not create a valid puzzle. In box 4 they all together add up to the same sum as in box one and 7.
Interpreting the rules there are many options (which none of them leads to a valid solution):
Box 4 can still go 2 ways: Cell 14569 and 258, or on the other hand cell 1458 and 2569.
You might also conclude there are 2 loops: one in box 1 and 4 (cell 1245 in box 4) and one in box 4 and 7 (cell 5689 in box 4).

Neat and fun!

Very nice. I got confused whether box 4 was a 7 cell segment, or a 3 cell segment AND a 5 cell segment, until the maths didn't work. Enjoyed it
