Sudoku Variants: Variety for Puzzle Fans

Those who can already solve classic Sudoku in their sleep often look for new challenges. Fortunately, there are numerous variants that expand the familiar game principle. They require new solving strategies and provide a breath of fresh air.

X-Sudoku (Diagonal Sudoku)

In X-Sudoku, the normal Sudoku rules apply. Additionally, however, the numbers 1 to 9 must also appear exactly once on the two main diagonals. This extra restriction requires a shift in thinking and offers new approaches to solving.

Killer Sudoku

Killer Sudoku combines Sudoku with mental arithmetic. The grid is divided into dashed areas. A sum is given for each area, which the numbers contained within must add up to. No number may be repeated within an area.

Samurai Sudoku

A Samurai Sudoku consists of five overlapping 9x9 grids. The four outer grids each share a 3x3 block with the middle grid. This variant is particularly time-consuming and requires a lot of stamina and concentration.

Mini and Maxi Sudokus

Mini Sudokus with 4x4 or 6x6 fields are suitable for beginners or children. Those who like it extreme can try Maxi Sudokus with 16x16 or even 25x25 fields. Letters are often used in addition to numbers here.
