Normal sudoku rules apply. Double arrows: the sum of the digits on the line is equal to the sum of the digits in the circles at each end of the line. Neighboring digits marked with a white Kropki dot are consecutive. Neighboring digits marked with a black Kropki dot have a 2 to 1 ratio. Not all dots are given. I think this puzzle is 2 stars out of 5 for difficulty for many solvers. As always, comments welcome. Thanks!
