PUZZLE NO. 226 : MATHRAX SUDOKU

 


RULES : Classic Sudoku rules apply. 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, while an O indicates that all four adjacent digits are odd. Digits may repeat within a circle. Not all circles are marked.
