The rules for sudoku are quite simple. A 9×9 square must be filled in with numbers from 1-9 with no repeated numbers in each line, horizontally or vertically. In addition, there are 3×3 squares marked out in the grid, and each of these squares can’t have any repeat numbers either. The rules may be simple but these puzzles can be quite a challenge.
Each puzzle provides some correct numbers – the fewer numbers provided, the more difficult the puzzle.
You can solve online or print it if you prefer pen (or pencil) and paper.
Have Fun!
