Onyx 4: First news!

Onyx 1.0 was released in 1996, twenty years ago! I have begun work on Onyx 4. Among many other new features, including significantly redesigned gameplay. A lot has changed in twenty years, and Onyx 4 is designed to be much more friendly to trans and nonbinary players. I've written a blog post about updating Onyx to be more inclusive here.

Onyx and macOS Sierra

Several people have emailed to ask if Onyx works with the new version of the Mac operating system, macOS Sierra. The answer is, yes, it does. Onyx 3.6 is compatible with macOS Sierra, as well as Windows 8 and Windows 10. (September 20, 2016)

Onyx 3.6.4 Now Available!

This is a free bug-fix release of Onyx. It fixes the following problems:

The Opt Out tokens might disappear or not draw correctly during a game.

Onyx 3.6 is now available!

Onyx 3.6 is a maintenance release that fixes bugs, improves compatibility with Windows 7 and Windows 8, and improves performance and compatibility with future versions of Mac OS X.

Onyx 3.6 is a free upgrade to Onyx 3 users.


To improve compliance with Windows Vista/7 programming guidelines and Windows 8 requirements, a significant change has been made to the location where Onyx stores its card deck files.

In the past, these files were stored in the Onyx folder in the Program Files folder. This could cause problems with the Card Editor, which in some configurations of Windows Vista and 7, and all configurations of Windows 8, would have to be run as Administrator.

With Onyx 3.6, the card deck files are now kept in the application data folder, which in Windows XP is

C:\\Users\(user)\Application Data\

and in Windows Vista and later is


The Uninstaller has been updated to reflect these new locations, and will remove the Card Deck files from the appropriate places if Onyx is uninstalled.

Because of this change, to keep Onyx 3.5 (and earlier) distinct from Onyx 3.6 if you have both installed, Onyx 3.6 now defaults to a Start menu group named "Onyx36" rather than "Onyx". You can install Onyx 3.6 without removing older versions of Onyx. This gives you a chance to save any card deck files you may have edited or created.


If you have edited or created card deck files with the Card Editor using previous versions of Onyx, you must copy the card deck files you have edited out of the previous Onyx application folder and into the location shown above. The Onyx 3.6 installer installs the Card Deck files in the new location, not in the Onyx folder in the Program Files folder!
