The most popular version of the program is 3.4. The program belongs to Games. We recommend checking the downloaded files with any free antivirus. This free Mac app is a product of Stichting Mathematisch Centrum and M. Stephenson.
From the developer:
This package has been updated to fix previously reported installation issues (if you have the old package and the game works, you do not need to get the new one). Program is free to download and is available in open source in sourceforge webpage in section files.
