How to Play 🔢 Sudoku

The 9×9 grid is divided into nine 3×3 boxes. Some numbers are pre-filled as clues. Fill in every empty cell with a digit from 1 to 9 so that each row, each column and each 3×3 box contains all nine digits with no repeats. Click a cell to select it, then tap a number on the on-screen numpad or type on your keyboard. Use the arrow keys to move between cells. Press Check to verify your answers, Hint for a free number, or New Game to start fresh. Choose Easy, Medium or Hard for different difficulty levels.
