📸 How to Upload Clear Images
Important: For best results, please upload clear, high-quality images of your sudoku. Our AI works best when it can clearly see all the numbers and grid lines.
✅ Do This
- • Take screenshots directly from your phone/tablet
- • Ensure good lighting when photographing
- • Keep the camera steady and focused
- • Crop to show only the sudoku grid
- • Use high resolution images (PNG, JPG, WebP)
- • Make sure all numbers are clearly visible
❌ Avoid This
- • Blurry or out-of-focus images
- • Photos taken in poor lighting
- • Images with shadows or glare
- • Angled or tilted photos
- • Very small or low-resolution images
- • Images where numbers are hard to read
