It may only involve numbers one through nine, but these fun math games can be head-scratching for anyone. Most math come from creating Sudokus: combinatorics used in counting valid Sudoku grids, group theory used to describe ideas of when two grids are equivalent, and computational complexity with regards to solving the number puzzles. Instead of solving, really challenge yourself by trying making your own Sudoku and having a friend solve it.
