Classic Sudoku
The 9×9 original.
Fill every row, column and 3×3 box with the digits 1 to 9. The starting digits sit on shaded squares; the rest are yours to work out.
- 9×9 board
- 3×3 boxes
- Digits 1 to 9
Four ways to play
Same nine digits. Four different puzzles.
Each one has its own daily puzzle, its own streak and a free pack of 50 to work through.
Killer Sudoku
No starting digits, only sums.
Dashed cages group the cells, and the small number in each cage is the sum of its cells. A digit can’t repeat inside a cage, and the usual row, column and box rules still apply.
- 9×9 board
- No starting digits
- Cage sums
Butterfly Sudoku
Four grids on one board.
A 12×12 board holds four overlapping 9×9 grids. Each of the four follows the normal rules, so a square in an overlap has to work in more than one grid.
- 12×12 board
- Four 9×9 grids
- Digits 1 to 9
Mini Sudoku
The short one.
A 6×6 grid with 2×3 boxes and the digits 1 to 6. Made for a short break.
- 6×6 board
- 2×3 boxes
- Digits 1 to 6
