Sudoku is a tool for solving, creating, and publishing Sudoku puzzles. You can save puzzles as SVG files. There is support for all of the numerical symbols in the Basic Multilingual Plane of the Unicode Standard (5.1). This would be helpful if you were developing Sudoku puzzles for non-Western peoples—or if you're practicing your numerals.

Sudoku is created with the Qt application framework, released under the GNU Public License. That means, among other things, that you are free to download it and use it, but not to re-sell it.

Qt is a cross-platform framework, so there is the possibility for using this on Mac OS X, Linux, etc. Right now I only have Windows executables because I only have a Windows machine. Perhaps some do-gooder will build versions for other operating systems and send them to me.

Executable Files

Sudoku for Windows

Source code

Download the source as a zip file

Or if you're feeling geeky:

git clone

I build in Windows with this, which assumes that Qt is installed and visible in your path:

qmake -config release

Of course your system would have something different from “mingw32-make”—probably just “make”—if you are not building from Windows using MinGW.
