Limitations

• Webcam solver cannot detect when a new puzzle has entered the frame, will try to warp the solution of the first puzzle it sees onto any subsequent puzzles
• OCR predictions are very spotty for hand written digits and stylized fonts
• Cannot solve puzzles that don't have a distinguishable four-point outer border
