Puzzlesight - Sudoku AI

Puzzlesight is the Sudoku scanner, game, and solver that brings paper puzzles into your phone. Use your camera on a newspaper, puzzle book, or printout—or import a photo—and get a playable 9x9 board without retyping every clue.

SCAN A SUDOKU IN SECONDS
Frame the complete grid and let on-device grid detection and OCR do the rest. Puzzlesight reads printed givens and detects handwritten answers, then gives you a clear review step. Correct a digit, clear a cell, or mark it as a Given or My Entry before you continue.

PLAY OR OPEN THE SOLVER
Import the scan to your library for a classic Sudoku game, or go straight to the guided solver. You can:
• Highlight the next solvable cell without revealing its value
• Reveal one answer when you are stuck
• Reveal and explain the logic behind the move
• Review or correct the scanned board at any time

LEARN REAL SUDOKU LOGIC
Hints go beyond giving you a number. Puzzlesight explains techniques such as last free cell, naked and hidden singles, pointing pairs, box-line reduction, pairs, triples, and X-Wing so you can solve more on your own.
