# Activation Code System

STEPN is an invite only game. User can earn ONE Activation Code for every 10 Energy spent, each user can only hold ONE activation code at a time, until it is used.

STEPN will disable Activation Code from time to time to facilitate marketing activities and promotion, if you do not need Activation Code to register, it means it is disabled.
