Hyper Sudoku is a variation of Sudoku that adds four additional regions to the puzzle. These regions are called hyperblocks, and they are each made up of nine cells. The rules of Hyper Sudoku are the same as regular Sudoku, with the following additional rule:
Each hyperblock must also contain the numbers 1 to 9, without repetitions.
This means that there are now a total of 133 cells in the puzzle, and each number from 1 to 9 must appear exactly once in each row, column, and hyperblock.
Hyper Sudoku is a more challenging puzzle than regular Sudoku, but it can also be more rewarding. If you are looking for a challenge, then Hyper Sudoku is a great option.
Here are some tips for solving Hyper Sudoku puzzles:
Start by looking for clues in the existing numbers. For example, if a number appears only once in a row, then it must be the missing number in that row.
Look for patterns in the numbers. For example, if a number appears in two of the three rows in a hyperblock, then it must also appear in the third row.
Use elimination to rule out impossible numbers. For example, if a number appears in a row and a column, then it cannot also appear in the corresponding hyperblock.
Be patient and persistent. Hyper Sudoku puzzles can be challenging, but they are also very satisfying to solve.
