While you can only buy Robux (Roblox currency), there are no real ways to earn them for free. However, there is a technique that can help you make some Robux in exchange for your Game Pass.

Roblox Pass the Bomb is a Battle Royale-style experience that mashes two classic kids’ games together: Tag and Baton Pass.

Using the Fighting Pass is pretty straightforward. The first move you should make is to open up Roblox, log in, and join Roblox Anime Fighting Simulator.

Remember, the Roblox demographic is mostly made up of young children and teenagers. So, if you charge Robux for a perishable item, make sure that it's also available without purchase in some fashion.
