I discovered something cool involving odd/even clues and I wanted to share it here. This puzzles difficulty for you may vary wildly depending on what type of solver you are.
Rules: Normal sudoku rules apply. Cells with a circle are odd, cells with a square are even. Digits on diagonals marked with a number sum to that number and may repeat.
This puzzle is also available on f-puzzles
Solution code: Rows 4 and 6
