1) Normal Sudoku Rules Apply.
2) Sandwich Rules: Numbers outside the grid give the sum of the digits found in between 1 and 9 in the corresponding row or column.
3) Even/Odd Rules: Opaque squares indicate that the digit in the corresponding cell is even. Likewise, opaque circles indicate the digit in the corresponding cell is odd.
4) XV Rules: Two cells separated by an X sum to 10. (No V's are given.) Negative constraint does not apply.
I'm not completely happy with how this turned out but I believe it's presentable. Still, I hope you have a positive experience with this puzzle!
