A Hyper Sudoku puzzle is very similar to a normal Sudoku puzzle, but there are four extra
regions. In this puzzle you will see there are four 3x3 shaded areas. Each of those shaded 3x3 areas
must contain the number 1-9 once and only once.
You can use all of the same rules when solving a Hyper Sudoku Puzzle, but you will also need to make use
of the four extra regions.
