This puzzle was created with my friends on stream. For a VOD of its creation see HERE.

Normal sudoku rules apply.

Between Lines: Cells along gray lines between two filled circles must have values between those in the circles.

Double Arrows: The sum of the digits along a red line connecting two circles is equal to the sum of the digits in the circles.

Odd/Even: The digit in the circle is odd. The digit in the square is even. There is no negative constraint on odds or evens.

For clarity, digits may repeat on lines of either type if allowed by other rules.
