# Android Sudoku Solver

*Under Development*

One of my friends at [Olin](http://www.olin.edu) occasionally posted a Sudoku puzzle on his dorm room whiteboard, attracting and challenging people walking by. One day, I and two other friends tried to solve one of his puzzles. Three of us eventually spent nearly an hour solving the problem!

I then asked myself if I knew the methods to solve a Sudoku puzzle, could I create a program that helps solve the puzzle for me? I mentioned the Sudoku solver program to my professors in the **WeCreate co-curricular** and they shared with us the [A Pencil-and-Paper Algorithm for Solving Sudoku Puzzles](http://www.ams.org/notices/200904/tx090400460p.pdf).

After a couple of weeks, I finally developed an Android application below. It's still not perfect and the algorithm isn't the most efficient one. But at least, I now have an app that helps me solve my friend’s Sudoku puzzles! 

In the future, I'd love to integrate image recognition into the app so that instead of manually inputting the numbers, users can take the picture of a Sudoku grid and the app can recognize and solve the puzzle by itself.
