What Makes a Brainrot Rare?
In Steal a Brainrot, rarity is determined by three main factors. Exist count is the most important for real-world value — it measures how many total copies of a brainrot exist across all game servers. The lower the exist count, the harder it is to obtain through trading or stealing.
Spawn rate determines how often a brainrot appears on the Red Carpet. OG brainrots have spawn rates as low as one in a quadrillion (0.00000000000000001) — most players will never see one spawn naturally.
Obtainability matters too. Signore Carapace has a higher exist count than Arcadragon, but Arcadragon requires Strawberry Elephant to craft — making it harder to produce in practice.
