What Is Steal A Brainrot?

Steal A Brainrot is a Roblox game where you buy brainrots, steal brainrots from other players, generate money and rebirth.1 Brainrots are funny internet meme characters with silly names like Tralalero Tralala, Bombardiro Crocodilo, and Tung Tung Tung Sahur. Players also trade them to get the rarest ones.

How Brainrot Values and Trading Work

Players judge a trade by how much each brainrot is worth compared to others. This calculator gives every brainrot a sample value to show how that comparison works. When you trade with another player, you want to make sure the items you give away are worth about the same as the items you get back. If you give away more value than you receive, you overpay. If you receive more value, you get the better deal. The trade checker uses a percent difference calculation to determine how far apart the two sides are.

Rarity, Demand, and Mutations

Each brainrot has a rarity tier: Common, Uncommon, Rare, Epic, Legendary, Secret, or OG. Higher rarity usually means higher value. Brainrots also have a demand level: high, medium, or low. A brainrot with high demand is easier to trade because more players want it.

Mutations are special versions of a brainrot, like Shiny, Gold, Rainbow, or Galaxy. A mutation adds a percentage boost to the brainrot's base value. For example, in this calculator a Galaxy mutation adds +150% to the value, making the brainrot worth 2.5 times its normal price. Always check if a brainrot has a mutation before you accept a trade.

What Does Base Income Mean?

Each brainrot earns you in-game currency every second. This is called base income per second. Rarer brainrots earn more income. This helps you save up and grow your collection faster over time.
