I really love solving this Argyle Sudoku puzzle. I hope you have as much fun trying to solve it as I did.

How to play Argyle Sudoku: The goal of Argyle Sudoku is to fill in the empty cells, one number in each, so that each column, row, and region contains the numbers 1-9 exactly once. Furthermore, Argyle Sudoku contains additional diagonals. Every marked diagonal line contains each number not more than once.
