Hyper sudoku puzzles are very similar to regular sudoku puzzles. However, regular sudoku puzzles are quite difficult and time consuming. Therefore, even if one simple rule was added to solving the sudokus, that would make it even more difficult. The rules for playing hyper sudoku include the same rules as the regular version where you are trying to get different numbers from number one through nine in the boxes that are rows and columns.
However, the hyper sudoku puzzle page looks different. It has blues boxes in the nine by nine grid. These boxes are 3 by 3 and then the numbers one through nine should not repeat in those boxes. Otherwise, everything else is the same especially the rules.
