Online registration for Onyx, the Game of Sexual Exploration

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. 

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.
