Game overview
How to Play?
Fill the grid with your keyboard so that every row, column and 3×3 box contains the digits 1 to 9, without repeating.
Once a number is in the grid nine times, it will lighten. You can disable this in Settings.
Use Normal Mode to enter numbers you are confident about. Use Candidate Mode to add or remove multiple possibilities for a square. You can also toggle candidates with your mouse, and pressing Space will switch between Fill and Candidate Mode.
