I've recently created an application that can solve Sudoku puzzles. I've compiled it for both Windows and Mac OS X. The OS X version should run on version 10.5 (Leopard) or higher but is only compiled for Intel Macs (for now).
If you'd like to check it out, I've made it available here: http://home.comcast.net/~nightfox/SudokuSolver/SudokuSolver.html
I've been able to run the Windows version in Windows 7 and Windows 2000, but fo r some reason it won't run in a Windows XP virtual machine I have.
