About

Sudoku Hint

Features
Read full description

Need help with a Sudoku puzzle on paper? Sudoku Hint is a simple AI-powered Sudoku solver, hint tool and mistake checker that works directly from a photo. Take a picture of your paper Sudoku and get one clear hint at a time — without revealing the entire solution. Unlike a traditional Sudoku solver where you have to enter the whole grid manually, Sudoku Hint uses your camera and AI to read the puzzle for you. It is designed to recognize both printed and handwritten Sudoku numbers. USE SUDOKU HINT TO: • Get a Sudoku hint when you are stuck • Check your Sudoku for mistakes • Find an incorrect handwritten number and see the correct value • Scan a paper Sudoku with your camera instead of typing in the grid • Get another hint from the same Sudoku photo • Use “Only look for errors” when you want to solve the rest yourself MADE FOR PAPER SUDOKU Sudoku Hint is especially useful if you enjoy newspaper, magazine or printed Sudoku puzzles. Simply photograph the complete 9×9 Sudoku grid and let the app analyze it. The app distinguishes between the original printed clues and numbers you have written in yourself. This makes it useful both as a Sudoku checker and as a source of hints when you need help with the next move. ONE HINT AT A TIME Sudoku Hint does not immediately show you the completed puzzle. Instead, it gives you one useful Sudoku clue at a time, so you can continue solving the puzzle yourself. If you only want to know whether you have made a mistake, enable “Only look for errors”. SIMPLE AND AD-FREE No ads. No account required. Just take a photo and ask for help. Sudoku Hint includes 3 free hints so you can try it before buying anything. Additional hints can be purchased inside the app. Sudoku Hint uses AI image recognition, which can occasionally misread a number. Always check the photographed grid and use your own judgement when following a hint.
