Frequently Asked Questions
What is Sudoku?
Sudoku is a logic-based number-placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 boxes contains all of the digits from 1 to 9. The puzzle provides a partially completed grid, which you need to complete.
How do I play?
Select an empty cell by clicking it, then enter a number from 1-9 that doesn't appear in the same row, column, or 3×3 box. Continue until all cells are filled correctly. Use logic to deduce the correct numbers based on the given clues. The game is won when all cells are filled correctly.
What are the controls?
Tap or click a cell to select it. Use number keys or the number pad to enter values. Use the pencil icon to toggle notes mode. Use backspace or 0 to clear a cell. Arrow keys move between cells, and spacebar toggles notes for the selected cell.
What are notes?
Notes (also called pencil marks) are small numbers you can write in cells to track possible values. Toggle notes mode with the pencil button, then click numbers to add or remove them as possibilities. Notes are crucial for solving harder puzzles and automatically update when you place numbers.
What do the difficulty levels mean?
Easy puzzles use basic logic and are perfect for beginners. Medium requires intermediate techniques. Hard introduces advanced strategies. Expert demands complex techniques and deep logical thinking. Master level requires expert-level pattern recognition and advanced solving methods. Extreme puzzles are the ultimate challenge, featuring minimal starting clues and requiring mastery of all solving techniques.
How is my score calculated?
Your score is based on completion time (faster is better), puzzle difficulty (harder gives more points), hints used (-100 points each), mistakes made (-50 points each), and a perfect game bonus (+500 points). Focus on accuracy over speed for the best scores!
What are the solving techniques?
Common techniques include single candidates (only one possible number for a cell), hidden singles (only one place for a number), pairs/triples (groups of numbers in specific cells), and advanced patterns like X-Wing. Chain techniques involve following logical sequences of candidates.
How do hints work?
You get 3 hints per game. Select an empty cell and click the hint button to reveal the correct number. Each hint reduces your score, so save them for when you're truly stuck. Hints cannot be undone.
Can I undo moves?
Yes! Click the undo button to reverse your last move. You can undo multiple moves in sequence, including both numbers and notes. While mistakes can be undone, hints cannot.
How can I improve?
Learn keyboard shortcuts, practice pattern recognition, master note-taking strategies, and start with easier difficulties. Study common Sudoku patterns and focus on accuracy before speed. Learn advanced techniques gradually as you improve.
