Sudoku Levels is a traditional logic game with a sleek, intuitive interface.
Select from easy, medium, or hard levels to tackle a fresh puzzle each time. Mind the clock and aim to fill the grid correctly, avoiding three errors.
Make use of notes to jot down potential numbers, retrace your steps, clear entries, and ask for clues if needed. The initial clue in each round is complimentary. The game saves your progress, logs stats for each difficulty, and notes your fastest times.
Earn rewards for victories, swift solutions, and precise play. See how you stack up against other players on the leaderboard.
The game is compatible with computers, tablets, and smartphones.
How to play
Your task is to fill a 9×9 grid with numbers from 1 to 9. Ensure that each digit appears only once in every row, column, and each of the 3×3 subgrids.
Some cells already contain numbers and are locked. Choose an empty cell and then pick a digit from those provided below the grid.
Switch on Notes mode to jot down potential candidates as smaller digits. Use Clear to erase the number in the selected cell, and Undo to reverse your last action.
If you find yourself stuck, you can ask for a hint. The first hint is free in each round, while extra hints require watching an ad. Entering a wrong digit counts as an error, and the round ends after three errors.
The timer measures your active play time and pauses when the game is on hold. Fill all the empty cells correctly to win.
