This classic puzzle game offers over 1000 unique 9x9 puzzles.

More puzzles are planned to be added in the near future.

Sudoku is a puzzle based on a small number of very simple rules:

• Every square has to contain a single number
• Only the numbers from 1 through to 9 can be used
• Each 3×3 box can only contain each number from 1 to 9 once
• Each vertical column can only contain each number from 1 to 9 once
• Each horizontal row can only contain each number from 1 to 9 once

Once the puzzle is solved, this means that every row, column, and 3×3 box will contain every number from 1 to 9 exactly once. 

In other words, no number can be repeated in any 3×3 box, row, or column. 

Happy Puzzling!
