# Activation Code System

**ADVENTURE GO** is an invite-only game. Users can earn one (1) activation code for every twenty (20) treasure box opened, each user can only hold a single activation code at a time until it is used.

**ADVENTURE GO** will disable activation code requirements from time to time to facilitate marketing activities and promotions. If you do not need an activation code to register, it means it is temporarily disabled.
