🎲RNG
Random Number Generation — a core mechanic in Brainrot games where outcomes (mutations, drops, rarity) are determined by random chance. RNG games like Brainrot Evolution and Scroll a Brainrot rely on rolling for rare results. Lower rarity = higher chance, legendary = very rare (0.1-1%).
🔄Rebirth
A progression mechanic where you reset your current progress (collection, levels, money) in exchange for permanent multipliers. Each rebirth typically gives a 1.5x boost. After multiple rebirths, you earn significantly faster. Found in Brainrot Clicker, Plants vs Brainrots, and Brainrot Evolution.
