# 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.
