Free Roblox Big Brain Simulator Codes (December 2020)

What are Roblox promo codes?

These are codes that you can use to get free cosmetic items for your avatar! You can equip them to your character in the Roblox Avatar area. You will keep these items permanently, so don’t worry about them disappearing. However, make sure to redeem the codes as soon as possible as they will expire after a certain time.
Unfortunately, we don’t know when new codes are coming to Roblox, so these are just as amazing to you as they are to me! If there’s new code, we’ll usually include it at the top of the page, so it’s the first thing you see.
