COSM-GAME Steal a Brainrot
Steal a Brainrot is a free-to-play multiplayer tycoon experience developed and published by BRAZILIAN SPYDER on Roblox. Players buy Brainrots, place them in a base to generate money, and attempt to steal Brainrots owned by other players. Progression focuses on earning cash, improving the base, collecting stronger Brainrots and using Rebirth to unlock longer-term upgrades. Its defining gameplay centers on the risk of stealing valuable units from rival bases while protecting a collection of your own.

Platforms and availability
The experience supports desktop, mobile and tablet play through Roblox. COSM-GAME tracks Windows PC, Mac, Chrome OS, Android and iOS / iPadOS because those platforms have current Roblox client support.
Gameplay and setting
Players purchase collectible Brainrots and place them inside a base where they continuously generate cash. The same multiplayer map allows players to enter rival bases and attempt to steal valuable Brainrots, while defensive timing and equipment help owners protect their collections.
Cash feeds the collection and base loop, while Rebirth provides longer-term progression. Slaps, troll gear, the backpack system, Lucky Blocks, mutations, traits, rituals and rotating machines add additional ways to compete for increasingly valuable Brainrots.
