## Sudoku Variants Series (040) - Mathrax Sudoku

(Published on 2. September 2014, 00:00 by Richard)

For this Sudoku Variants Project I have planned to publish a different Sudoku variant every Tuesday. I will see how long it takes before I am running out of ideas.

Mathrax Sudoku
Place the digits from 1 tot 9 in every row, column and 3x3-block. Some intersections of the grid lines are marked by a number and an operator (+, -, X, /) in a circle. The number is the result of the operation, applied to both pairs of diagonally opposite cells. An "E" in the circle indicates that all four adjacent digits are even; an "O" indicates that all four adjacent digits are odd.

Solution code: Row 8, followed by column 8.
