Twister

Rules:

Normal sudoku rules apply. Adjacent red circles have different parities i.e. one digit is odd and the other digit is even. Within each region, the blue circles have the same sum. A digit in a yellow circle matches at least one of the row, column, or box number. Adjacent green circles must differ by at least 5. A square and a circle of the same colour may not contain the same digit. Digits along an arrow must sum to the digit in that arrow's circle.
