About game
Logic puzzles remain the ultimate way to sharpen your mind while killing time during your daily commute. Sudoku Levels brings the classic number grid to your screen with a clean interface that keeps your focus on every digit. You fill the nine by nine board by ensuring numbers one through nine never repeat in any row, column, or square. Selecting an empty cell allows you to input your guess, and you can switch to notes mode to pencil in possible candidates. Mistakes happen, but keep your error count below three or the round ends abruptly. The built-in timer pushes you to beat your personal best speed with each new session. Tracking your progress through various difficulty levels feels rewarding as you climb the global leaderboards. You can jump into this browser based головоломка right now without any downloads or registration blocks.
How to play
The goal is to fill the 9×9 board with digits from 1 to 9. Digits must not repeat in any row, column, or 3×3 block.
Some cells are already filled and cannot be changed. Select an empty cell, then choose a digit below the board.
Enable Notes mode to enter possible candidates as small digits. Use Clear to remove the value from the selected cell and Undo to revert your latest move.
If you get stuck, request a hint. The first hint in every round is free, while additional hints are available after watching an advertisement. Entering an incorrect digit counts as a mistake. The round ends after three mistakes.
The timer tracks active playing time and stops while the game is paused. Correctly fill every empty cell to win
