# Understanding the Game ### Which tokens? As mentioned, $VOID is the powerhouse of Onessus. It is the in-game crypto token that fuels the economy of NiftyVille. You can visit [here](/niftyville/niftyville-play-to-earn/how-to-earn.md) to learn more about how to earn. ### NiftyCoins and Progression \ NiftyCoins (NC) are a secondary in-game **non-crypto token**. You can find and earn these tokens on the server and level up your character experience. NiftyCoins + Levels are the progression system. #### What does this mean? The progression system is for free-to-play players who may not want to participate in linking a supported wallet, but still want to be a part of the community. You can level up and find NiftyCoins and unlock free skins, weapons, vehicles that are mostly NON-NFT. So if you'd like, you can start at F2P and still get to P2E. The progression system applies for all players. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
