In PvB, every player farms their own garden. You start with a basic plot and a tiny plant. As the game’s description puts it, you “buy a seed & plant it in your garden”, and then “your plants fight brainrots for you! The brainrots generate money!” Rolimons. Each defeated brainrot drops cash or resources. You use the income to buy stronger plants and gear. Occasionally special boss brainrots spawn: after every 500 normal kills, a banner appears “A Boss Has Spawned!” Beebom. Defeating a boss yields massive income – even early bosses payout hundreds to thousands of dollars per second. Over time, captured brainrots themselves become decorations in your base, passively adding income.
