Steal a Brainrot Complete Guide October 2026
Posted: Fri Oct 23, 2026 9:56 am
Quick Summary
Rarity in Steal a Brainrot is a spawn-difficulty rating. It is not a value rating. Two brainrots carrying the same rarity badge can earn wildly different amounts per second, and that gap is what traders actually argue about.
The eight tiers, with the cost and income ranges attached to them
Secret is the tier with the widest internal spread. The cheapest end and the most expensive end sit in the same bucket, which is why lumping every Secret together misleads. OG sits above Secret and Brainrot God sits below it.
How the Red Carpet decides what spawns
The wiki extracts a value it calls RoadWeight straight out of the game files and says plainly that these are not percentages and not chances expressed as X in Y. They are weights. A brainrot with a weight of 100 is not guaranteed; it is simply the baseline everything else is measured against.
The wiki notes that since September 6, 2025 the OG weights are stored in the ServerStorage folder, which decompilers cannot read, so the newest OG rows are estimates. Every Secret entry it publishes sits between 0.0003 and 1E-10.
The one mechanic most players miss: the 150 percent resale
A brainrot that walks onto your base does not have to stay yours. Another player can buy it off you while it is still travelling, at 150 percent of its base cost, and the brainrot then changes direction and walks to that player instead. Every brainrot of every rarity can do this, which means a Legendary that just spawned is also a Legendary that can be taken from you before you have finished deciding whether to spend on it.
Exist counts: the supply number the game now shows you
Exist count is the number of copies of one brainrot that exist across every server. It is a supply measurement, not a price.
Acquisition routes: where each tier actually comes from
The Eldorado list assigns each brainrot an obtain method, and the split matters more than the tier label.
The Trade Machine, and why it exists
The Trade Machine is the official in-game trading system. It was added on February 21, 2026 as part of the TRADE MACHINE event, Update 39. It came out of a poll Sammy ran asking whether the game should get one, and it exists to replace trust-based trades arranged in Discord or in chat, where one side simply does not deliver. The wiki says it handles same-server and cross-server trades, and that you should check the in-game UI for the exact options and limits.
Two things that break the pattern
A rare brainrot is not automatically worth more than a well-rolled lower tier. Lootester's worked example is Cooki and Milki, which is officially Secret rarity with a comparatively low buy-in cost and an unusually high income per second, which is why traders value it above units that are nominally rarer and earn less.
The other is mutation potential. Rainbow multiplies income by 10x on any rarity, so a Rainbow-rolled Rare can out-earn an un-mutated Legendary. Lootester lists Gold at 1.25x, Diamond at 1.5x, Lava at about 6x, and Rainbow at 10x, and notes that a Rainbow-mutated lower-rarity unit is frequently the better purchase. Mutations are a separate system with their own topic already on this board.
FAQ
Q: How many brainrots are in Steal a Brainrot right now?
A: The index tracks more than 580 base brainrots across the eight rarity tiers. Eldorado's October 2026 exist-count explainer says 515 or more base brainrots and notes that with 13 mutations and countless traits the number of distinct variants runs into the tens of thousands.
Q: Is Secret the rarest tier in Steal a Brainrot?
A: No. OG is the rarest. Secret sits above Brainrot God and below OG, which makes Secret the highest tier you can realistically own more than one of.
Q: Are Steal a Brainrot spawn rates official?
A: No. Do Big Studios has never published spawn percentages. The RoadWeight values come from the game files as extracted by the community, and the percentages you see on trackers are estimates from large-sample counting.
Q: What does a RoadWeight actually mean?
A: It is a relative weight, not a chance. Noobini Pizzanini sits at 100 and that is the baseline. The wiki states explicitly that if these were percentages, only Noobini Pizzanini could ever spawn, and that is not what happens.
Q: Which brainrot spawns the most often on the Red Carpet?
A: By weight, Noobini Pizzanini at 100, then Lirili Larila at 55 and Tim Cheese at 50. On Admin Abuse spawns the wiki's answer is different: Sammy spawns La Vacca Saturno Saturnita most often and says "someone said la vaca" before he does.
Q: How long does the Red Carpet guarantee between spawns?
A: Five minutes for Legendary, fifteen minutes for Mythic, and an estimated forty-five minutes for Brainrot God. The wiki flags the Brainrot God figure as an estimate because those units now spawn easier than they did a few months ago even though the file weights did not change.
Q: What is the Trade Machine for?
A: It is the official in-game trade system from February 21, 2026. It exists so trades do not depend on one side trusting the other, and the wiki advises using it instead of arranging a swap outside the game.
Q: Do codes still work in October 2026?
A: The trackers disagree. Eldorado says none are active and files BESTBRAINROTEVER as sold out. Dexerto and game.guide list BESTBRAINROTEVER, and game.guide adds saturn. Try BESTBRAINROTEVER first and do not pay anyone for a code.
Sources
- Steal a Brainrot has eight rarity tiers, from Common up to OG. The index tracks more than 580 base brainrots, and eight separate systems add copies: the Red Carpet, stealing, Admin Abuse, Lucky Blocks, ritual summons, fusing, code redemption, and the Trade Machine.
- Do Big Studios has never published spawn percentages. Every rate you see is either a RoadWeight value the community pulled out of the game files, or an estimate from a large-sample tracker.
- The Red Carpet's guaranteed spawn timers are 5 minutes for Legendary, 15 minutes for Mythic, and an estimated 45 minutes for Brainrot God. Secret and OG carry no such timer.
- Exist counts arrived in Update 56. They show in the Index, above the brainrot in your base, and in the Trade Machine, and they update roughly hourly.
- The codes situation is split across trackers. Eldorado says no code is active. Dexerto and game.guide list BESTBRAINROTEVER, and game.guide also lists saturn, both spawning La Vacca Saturno Saturnita.

The eight tiers, with the cost and income ranges attached to them
- Common: cost 25 to 1,700 dollars, income 1 to 14 per second

- Mythic: cost 350,000 to 6.2 million dollars, income 1,900 to 18,700 per second
- Brainrot God: cost 5 million to 80 million dollars, income 17,500 to 324,000 per second
- Secret: cost 50 million to 435 billion dollars, income 300,000 to 435 million per second
- OG: cost 450 billion to 1 trillion dollars, income 450 million to 1 billion per second
Secret is the tier with the widest internal spread. The cheapest end and the most expensive end sit in the same bucket, which is why lumping every Secret together misleads. OG sits above Secret and Brainrot God sits below it.

| Trippi Troppi | Rare | 30 |
| Cappuccino Assassino | Epic | 13 |

Exist counts: the supply number the game now shows you
Exist count is the number of copies of one brainrot that exist across every server. It is a supply measurement, not a price.
- Exist Counts shipped in Update 56, and they appear as a tooltip in the Index, as a 1 of 1 tag in the trade machine, above the brainrot in your base, and in the book in the centre of the Trade Plaza.
- According to a test the wiki cites, counts and the 1 of 1 tag both update about once an hour.
- SpyderSammy said on the community server that not every brainrot's exist will be visible if full counts ship, and when the feature went live that turned out to be accurate.
- Counts move in both directions. Headless Horseman is the wiki's example: its exist count used to read 139 and later read 74, because players sell, void, fuse, steal, or have accounts removed.
- The wiki's own page carries a warning that exist count modules can be openly edited by anyone, that counts not sourced from the Exist Count Discord server, the wiki, or Sammy are most likely fabricated to scam you, and that for most brainrots the brainrot viewer in game is more accurate than the wiki table.
Acquisition routes: where each tier actually comes from
The Eldorado list assigns each brainrot an obtain method, and the split matters more than the tier label.
- Red Carpet: the only source for the cheap commons and for several top-tier units. Noobini Pizzanini, Tim Cheese, Trippi Troppi, Cocofanto Elefanto, Tralalero Tralala, La Vacca Saturno Saturnita, Skibidi Toilet, Meowl, and Strawberry Elephant all list it.
- Stealing: the second route, and the one that costs you nothing but a shield.
- Admin Abuse events: Unclito Samito lists this as its source.
- Fusing and crafting machines: Agarrini la Palini from the First Fuse Machine, Malame Amarele and Caramello Filtrello from the First Craft Machine, Dragon Gingerini from Santa's Fuse.
- Lucky Blocks: Love Love Love Sahur from the Heart Lucky Block, Kraken from the Octo Lucky Block, Celestial Pegasus from the Secret Lucky Block.
- Ritual summons: Noo my Examen from the Dul Dul Dul ritual and John Doe from the Cave Ritual.
- Codes: BESTBRAINROTEVER and saturn both spawn La Vacca Saturno Saturnita.
- MerchShop DLC codes: Pineaplino, Lazy Ducky, Tenini Ballini, and Pancake and Syrup.
- Eldorado, page dated September 22, 2026: "There are NO active Steal a Brainrot codes at the moment." It files BESTBRAINROTEVER under expired codes, marked sold out.
- Dexerto, updated October 12, 2026: one active code, BESTBRAINROTEVER, reward La Vacca Saturno Saturnita.
- game.guide, checked October 21, 2026: two active codes, BESTBRAINROTEVER added June 21, 2026 and saturn added July 31, 2026, both spawning La Vacca Saturno Saturnita.
- Beebom lists the same pair. Timesaver, checking on October 8, 2026, also names BESTBRAINROTEVER alone.
- Dexerto adds a second point worth repeating: Steal a Brainrot codes do not hand out cash or boosts. The rewards are exclusive brainrots and limited-time variants.
- Codes land in their own section on the left side of the screen after the Summer Update, per Eldorado. Dexerto describes the same place as a CODES option that opens a text box and a SUBMIT button.
