When you start playing Steal a Brainrot, you receive a small sum of money to invest in your first Brainrots. Players can choose to buy Brainrots from the parade of meme characters or take a riskier route by sneaking into other players’ bases to steal theirs. Every Brainrot you own generates passive income when placed in your private base, helping you accumulate funds faster. The more Brainrots you have, the higher your income grows, which can then be reinvested to purchase stronger Brainrots, enhance your defenses, or unlock rebirths for long-term bonuses. The game encourages players to balance legitimate purchases with daring thefts to maximize wealth and strategic advantage.
