Normal sudoku rules apply.
Opposite Arrows: A digit on an arrow indicates how many digits of the opposite parity are in the direction of the arrow. (ie if the digit is even, it counts odd digits, and vice versa).
Parity Lines: All lines are parity lines; every pair of cells connected by a line must contain an even and odd digit.
Summit Lines: Digits along a blue line must be ascending or descending, with 1 and 9 reversing the ascension/descension. (eg if digits along a blue line are 2-5-6-9-8-5, the sequence is ascending until the 9 causes a descension).
Renban Lines: Digits along a pink line contain a consecutive set of digits that are not required to be in consecutive order.
