For the design I wanted to make two lines containing each type of clue once. I think it looks pretty nice. I needed two extra clues for uniqueness. It is not really a hard puzzle, especially compared to some other Sudokus on my blog. It should still be fun to solve. Enjoy.
Rules for Sudoku
In this Sudoku 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.
