# Skins BitBrawl is a competitive game, so the only difference between brawlers in the game is how they appear. Players can use any of our **20+ partnered projects** to play with for free.\ \ However, if they want to customize their looks, they'll need to purchase a BitBrawl NFT. When entering the game, players will connect their wallet holding their brawlers. The metadata will be read, allowing players to change their in-game brawler look. Skins are only cosmetic, so the power of each brawler is still equal. --- # 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.
