Online Upgrade for Onyx, the Game of Sexual Exploration, version 1.x or 2.x to version 3

Registration will give you a serial number, which you will need in order to play the game at higher levels, use custom card deck files, and create your own card deck files.

The serial number will be sent to you in email, usually in 2-3 business days. 

Onyx 3 is the first upgrade that requires a new registration. Please note that your Onyx 1.x/Onyx 2.x serial number will not work in Onyx 3!

Important: If you do not receive your serial number, please check your spam filter! Some automatic spam filters incorrectly flag the serial number email as spam.
