Variants of Sudoku
Sudoku has inspired numerous variants, including different grid sizes (e.g., 4×4, 6×6, 12×12), irregularly shaped regions, diagonal Sudoku, and more complex rule sets. Some of these popular varients are:
- Diagonal Sudoku: In addition to the usual row, column, and 3×3 box constraints, the main diagonals also must contain the numbers 1 through 9.
- Irregular Sudoku (Jigsaw Sudoku): Instead of 3×3 boxes, irregularly shaped regions are used, adding an extra layer of complexity to the puzzle.
- Killer Sudoku: In this variant, the grid is divided into irregularly shaped regions, and instead of providing initial numbers, the puzzle gives sums of numbers in certain areas.
- X Sudoku (Double Diagonal Sudoku): Similar to Diagonal Sudoku, but with two main diagonals crossing each other. Both diagonals must contain the numbers 1 through 9.
- Hyper Sudoku: This variant includes additional regions in the shape of a plus sign (+) in the center of the puzzle. These regions must also contain the numbers 1 through 9.
