Once and For All

This is my attempt at using the trending new rule which disallows repeats for each constraint.
Rules:
#1 Normal sudoku rules apply.
Each of the following constraint types may contain no repeated digits anywhere in the puzzle:
#2 A digit in a grey square is even.
#3 A digit in a grey circle is odd.
#4 For digits in cells separated by a white dot, one must be one greater than the other.
#5 For digits in cells separated by a black dot, one must be double the other.
#6 Adjacent digits along an orange line must differ by 4 or more.

Very fun puzzle. Got stuck after solving all of the digits on the constraints until I found a naked single.

For me, this was absolutely brutal. Great construction tho!

Very nice especially working out the missing digit on the white dots and orange lines. A 3 rating is fair.

Really cool break-in, and a reasonably good way to finish the puzzle after using the clues.
