The Core Loop: Treadmill -> Speed -> Steal -> Incubate -> Cash
Every new player spawns into Steal A Brainrot Egg with a base speed of 10. You cannot immediately run into high-level egg nests because zone guardians will easily catch, headbutt, and kill you. Your first session revolves around a tight feedback loop: step on the starting treadmill at your base to build Speed, run into low-threat zones (Capybara/Lion) to grab an egg, carry the egg across your base's boundary line, wait for the incubator countdown, and deploy hatched Brainrots to earn passive Cash per second ($/s). Reinvest that cash directly into upgrading your treadmill to gain +15, +30, or +50 speed per step.
