Sudoku Solver

This application is a solver for Sudoku puzzles. I use it mainly as a kind of “Hello World” application for testing JavaFX.

Run the application and it presents an empty Sudoku grid. Start putting in the numbers you have and it should fill in the rest! If you have a puzzle it cannot solve please send it to me at so I can see if I can improve its abilities!


The application is built in JavaFX and is supplied as a zip file containing a custom JRE, so should not need any dependencies to run. Download the version for your operating system below, unzip to a suitable location, and then run the bin/sudoku.bat (Windows) or bin/sudoku (Mac/Linux) script to launch the application.
