WIS is an Invite-Only game.
Users can get an Activation Code for every 10 Energy they spent, and each user can only hold one Activation Code at a time, until it is used.
WIS will disable the Activation Code from time to time to facilitate marketing activities and promotions, if you do not need the Activation Code to register, it means it is disabled.
After getting the Invitation Code, users need to hold a specific NFT in order to have a full game experience.
If there is no specific NFT, activated users can experience part of the game content through the rental system.
