Want to give your mind a workout? Classic Sudoku is the globe's favorite logic puzzle! It's not just about filling in numbers; it's a stimulating challenge that sharpens your focus and helps you unwind.
How to play
The aim of Classic Sudoku is to complete a 9×9 grid with numbers in such a way that each row, each column, and every 3×3 subgrid includes all digits from 1 to 9 without repetitions.
Controls:
- On PC: use the keyboard to input numbers and navigate the grid with arrow keys.
- On smartphones: intuitive touch controls with large, convenient buttons.
During the game, you can:
- Clear a cell by selecting it and pressing «ERASE».
- Revert your last move with the «UNDO» button.
- Get a hint by pressing «HINT». After viewing a short ad, the game will fill in the correct number in one of the empty cells (randomly or in the cell you chose).
To win, you need to fill the entire grid correctly, without errors or empty cells. Points are awarded based on the difficulty level and the time taken. Your final score will be saved and added to the leaderboard.
