The brief
Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9. The green lines are Whisper lines: digits in adjacent cells connected by a green line must have a difference of at least 5. Digits on an arrow must sum to the digit in the attached circle. Digits separated by a black dot must be in a 1:2 ratio. Digits separated by a white dot must be consecutive.
