In the early 21st century, the digital age propelled Sudoku to new heights, making it a household name.

Classic Sudoku is the most well-known and widely played type of Sudoku. It features a 9×9 grid, divided into nine 3×3 regions, where the objective is to fill in the grid with numbers from 1 to 9. Each row, column, and region must contain each number exactly once.

Classic Sudoku puzzles come in varying levels of difficulty, from easy to fiendishly challenging, and they require logical thinking, pattern recognition, and deduction to solve.

2. Diagonal Sudoku

Diagonal Sudoku adds an extra layer of complexity to the classic version. In addition to the standard rules, diagonal Sudoku puzzles require that both main diagonals also contain each number from 1 to 9 without repetition. This subtle variation introduces new problem-solving strategies and makes an engaging twist on the traditional Sudoku.

3. Irregular Sudoku

Irregular Sudoku, also known as Jigsaw Sudoku, breaks away from the traditional 3×3 regions. In this variant, the regions have irregular shapes, which can be challenging to work with. While the standard Sudoku rules still apply (no repetition of numbers in rows, columns, or regions), the irregular patterns add an extra layer of complexity, making Irregular Sudoku a favorite among experienced players looking for a fresh challenge.

4. X-Sudoku

X-Sudoku is a captivating variant that requires players to adhere to the standard Sudoku rules while also ensuring that two main diagonals, forming an “X” shape, do not contain any repeated numbers. The additional constraint of the diagonals introduces new solving strategies, and players must consider both the row and column rules as well as the diagonal rule.

5. Killer Sudoku

Killer Sudoku is a numeric puzzle that combines Sudoku with mathematical operations. In this variant, the grid is divided into irregularly shaped regions, and a small number accompanies each region. The objective is to fill in the grid so that the numbers in each region satisfy the mathematical operation (e.g., addition or multiplication) given by the small number. 

Killer Sudoku offers a unique and strategic challenge, as players must apply math skills alongside traditional Sudoku logic to solve the puzzle. It’s a favorite among those who enjoy a more cerebral Sudoku experience.
