The rules of sudoku
Your goal is to fill every row, column and 3 x 3 grid on the field with the numbers 1 through 9.
No numeral must repeat in any of the rows, columns or 3×3 grid squares.
Use context to identify the location of the missing numbers.
Difficulty and hints
The fewer the starting numbers of a sudoku puzzle are, the harder it is to solve.
You can use the hints button to show you some more numbers.
You only have 5 hints for the entire game. Use them wisely.
We recommend using hints when you’re stuck with a cell that has 2 possible answers.
Tips
Fortunately, you can write your guesses as notes to keep track of your guesses
Use the note tool to add the possible numbers something could be in the space provided.
To remove a note, turn off the note tool and superimpose the correct answer on it.
From there, it becomes a process of elimination.
Target Audience
The game is suited for players who like sudoku puzzle games.
