How does the Sudoku solver work?
Our Sudoku solver uses advanced algorithms and techniques like single candidate, hidden singles, and X-wing patterns to solve puzzles. You can either input numbers manually or upload a photo of your puzzle.
Can I upload a photo of my puzzle?
Yes! You can upload a photo of your Sudoku puzzle, and our OCR technology will recognize the numbers automatically. Make sure the image is clear and well-lit for best results.
What should I do if the solver gets stuck?
If the solver seems stuck, first check if all numbers are entered correctly. You can use the 'Check Progress' button to validate your current solution. If needed, you can also use the 'Get Hint' feature for assistance.
Is there a limit to how many puzzles I can solve?
No, there's no limit! You can solve as many puzzles as you want. The solver is free to use and available 24/7.
How accurate is the OCR recognition?
Our OCR technology is highly accurate when provided with clear images. For best results, ensure good lighting, minimal glare, and that the puzzle takes up most of the frame. You can always manually correct any misread numbers if needed.
Can I get explanations for each solving step?
Yes! Our solver provides detailed explanations for each step, helping you understand the logic behind the solution. This is especially useful if you want to improve your own solving skills.
What solving techniques does the solver use?
The solver employs a wide range of techniques from basic to advanced, including Single Candidates, Hidden Singles, Pairs, X-Wing patterns, and more. You can learn about these techniques in our documentation.
Can I save my progress?
This feature is coming soon! Progress saving will be added in an upcoming update - check our changelog for details. For now, we recommend completing puzzles in one session.
Does the solver work on mobile devices?
Yes, our solver is fully responsive and works on all devices. The OCR scanner can use your mobile device's camera for easy puzzle input.
What if I make a mistake while entering numbers?
Don't worry! You can use the 'Undo' button to reverse your last action, or the 'Clear' button to start over. The solver also validates your input to prevent invalid configurations.
