Steal a Brainrot: the Roblox phenomenon taking over 2025

Steal a Brainrot, created in May 2025, quickly became one of the most played games on Roblox.

With more than 10.2 million concurrent users, it surpassed Blox Fruits and is only behind Grow a Garden in the platform’s history. Its formula combines collecting, defending, and stealing characters called brainrots, with an aesthetic linked to meme culture.

What is Steal a Brainrot?

The core of the game is to collect brainrots, quirky characters that automatically generate money. The challenge is that other players can infiltrate bases to steal them, creating a chaotic multiplayer dynamic.

There are 63 unique brainrots classified by rarity: from the simple Noobini Pizzanini that generates $1 per second, to the legendary Tralalero Tralala that produces $50,000 per second.

The game is not only about collecting, but also about defending and attacking. Bases protected with laser doors, traps, and simple weapons are part of the system, while stealing slows down the player and alerts the original owner.

How to Play

1. Each player starts with 100 coins and a protected base.
2. The first brainrot is acquired on a central conveyor belt.
3. From there, income is generated to expand the base and obtain new brainrots.
4. Rivals can enter bases when they are temporarily unlocked and steal characters.
5. There are rebirths that reset progress in exchange for permanent advantages, such as more base slots or money multipliers.

The Viral Impact

The game went viral on TikTok, where phrases like “they stole my Vacca Saturno Saturnita” became memes shared by thousands of users. This exposure on social media consolidated the game’s popularity beyond Roblox itself.

However, debates also emerged: some experts warned about risks of virtual harassment due to the stealing mechanics between players.

Why Is It So Popular?

The mix of competition, viral humor, and accessibility explains the success of Steal a Brainrot. It is available on PC, mobile, and consoles, with frequent updates introducing new mechanics. The simplicity of its premise, combined with the unpredictability of matches, makes it attractive for streamers and entire communities.
