Play in any (semi-)modern web browser (even tablets and phones—no plugins required)
My intent with this adaptation is to make the puzzles playable on tablets, phones, and anywhere else you find a reasonable web browser. (Though on slower devices, some puzzles may take a very long time to generate new games at the more-complex levels.) You can report any problems in this project's issue tracker.
