Sudoku is a challenging game to learn and master. It can be either a simple 3 × 3 mesh or a mesh of a higher complexity. The game is very addicting and it is a great puzzle game. However, sometimes you want a little help. A good sudoku solver helps here. You can double check the solution to make sure there are no errors. Plus, it can help you solve a tricky puzzle if you get stuck.
All Sudoku solvers on Android do basically the same thing. You use the camera or the numeric keypad to enter the various numbers that the puzzle gives you. The solver will then insert the rest for you. The only difference between apps is the size of the grid supported and the user interface. Otherwise, they all work basically the same way. This is why this list is shorter than most of our other lists. Below are the best Sudoku solvers for Android.
Sudoku Solver
Developer: Jamie McDonald
This is one of the most popular web Sudoku solvers for Android. This is a super classic app. It solves puzzles in the traditional 9x9 grid that you find in newspapers and magazines. You just enter the numbers, you enter the already existing numbers and it will solve them. This option will work for many because it works with the most popular version of Sudoku. Plus, the app is completely free with no in-app purchases or ads.
Sudoku Solver - Snap Solve Sudoku V2
Developer: Beebeeoii
Another great program for solving Sudoku on mobile devices. It works the same as Sudoku Solver, except that it supports OCR. Basically, you can take a picture of the puzzle from the book or paper you found it on, and the app will enter the numbers for you. You can do it manually if necessary. The app stores scanned Sudoku boards for future use when needed. The app is free to use, but you can donate if you want.
Sudoku Expert
Developer: Aeiou
It is a mixture of online Sudoku, Sudoku teacher and Sudoku game. The app contains over 5000 puzzles. However, it's also a built-in solver where you enter your own puzzle and the app will solve it for you if needed. The controls are actually pretty straightforward, although they can feel a little cramped on small screens and some people don't like the blue tint. Anyway, it's definitely good to use as a solver, and it doesn't hurt to have 5,000 more other puzzles with you.
Sudoku Solver (Camera)
Developer: Robinson Industries
It's a nifty little tool for Sudoku aficionados as well as a great demonstration of AR and OCR technologies. The app opens the camera, you point the camera at a sudoku puzzle. The application recognizes the riddle and solves it for you right on the spot. You simply press the freeze button to stop the application and record the responses. It's a great tool for checking if you've solved a puzzle correctly, or as a solver in case you get stuck.
Sudoku Solver
Developer: Shai Alkoby
Another worthy solver. It works with both a typical 9x9 grid and a 16x16 grid. Otherwise, it works like most others. You enter the numbers you know, and the application fills in the rest. It is one of the few that can handle both sizes, so it is a good tool for the casual free online Sudoku fan. We also love that this app is configured to show the numbers one at a time as clues, rather than just giving the whole answer at once. This is a good option for people learning Sudoku and people who want to check their answers.
