• Illustration — Stealing Brainrots while fending off other players is central to the game. In Steal a Brainrot, players aim to acquire Brainrots—voxel characters based on the 2025 Internet meme Italian brainrot—and build wealth. The player starts with a base to store their Brainrots and a small amount of currency. A conveyor belt bisects the map, offering players the opportunity to purchase Brainrots, which passively generate income over time. Players progress by purchasing rarer and more expensive Brainrots from the conveyor or stealing them from other players, a gameplay loop comparable to the sport capture the flag. To defend against theft attempts, the base has a button which generates a temporary shield. Players can purchase gear such as traps and items from the store to aid with defense or stealing, costing either in-game currency or Roblox's premium currency Robux. Players can "rebirth", resetting their progress in exchange for better stats and additional currency. Like Grow a Garden, the developers host special events often called "admin abuse" in which exclusive characters can be obtained. Kara Phillips of PCGamer described these events as a "sensory overload".

Alongside Grow a Garden, Steal a Brainrot is one of the most popular games on Roblox of all time, and had an average concurrent users (CCU) of one million in September 2025. In July 2025, Steal a Brainrot reached 7 billion visits, and had a peak CCU of 5 million players. In August 2025, Steal a Brainrot saw a peak CCU of 20 million, surpassing Fortnite, which previously held the all-time CCU record of 15.3 million. On August 23, an event featuring a mock "admin war" between SpyderSammy and Grow a Garden developer Jandel drove each game to break their respective CCU records: Grow a Garden reached at least 22.3 million CCU, while Steal a Brainrot became the second Roblox game to surpass 20 million CCU. Additionally, the event drove Roblox to achieve a new platform-wide CCU record of 47.4 million players, beating the July 2025 record of 32.69 million. On September 13, with their Extinct Event, the game saw a CCU peak of 24 million, surpassing the Grow a Garden record. In October, the game achieved a CCU peak of 25.4 million.

Epic Games officially licensed Steal a Brainrot for use in sandbox video game Fortnite Creative. Titled Steal the Brainrot and released in July 2025, the replica beat the CCU record for a Fortnite Creative Island with its 400k CCU peak, breaking the previous record of 235k players achieved by Super Red vs Blue in May 2025. On September 13, the Island hit a new peak with 500k CCU, temporarily surpassing that of the official battle royale mode. Epic Games CEO Tim Sweeney celebrated the game's success through a series of retweets. In early September, Sammy voluntarily removed the Tung Tung Tung Sahur character from the game after a licensing dispute with its creator Noxa and the brand agency Mememtum Lab. The agency has stated that they are open to continued licensing talks. The character was added back to the game on November 29, 2025. The game is registered at the U.S Copyright Office (PA002544969). In October 2025, Spyder Games sued the creator of an unlicensed copy of Steal a Brainrot called Stealing Brainrots within Fortnite Creative, claiming that the Stealing Brainrots infringed on Spyder's copyrights. A film adaptation of the game is in the works, set to be produced by Story Kitchen in partnership with DoBig Studios. In January 2026, Steal a Brainrot hosted a brief virtual concert in which Bruno Mars performed I Just Might, the 2026 lead single of the album The Romantic (making it the first time Mars has performed the album live), and 2012 single Locked Out Of Heaven. Players were issued exclusive items and brainrots during the concert. The event saw a peak of 12.8 million CCU, as well as 10 million livestream watchers.
