Extinct Matteo

Extinct Matteo is a Secret brainrot in the Roblox game Steal a Brainrot. It costs 140M and earns 625K per second, which works out to 37.5M per minute, 2.25B per hour and 54B over a full day of earning time. At its base rate, Extinct Matteo pays back its own price in about 4 minutes. Among the 102 Secret brainrots in our database it ranks number 77 for income, and number 79 of 257 across every rarity, which puts it ahead of about 70 percent of all brainrots we track.

This page covers everything you need to decide whether Extinct Matteo belongs in your base: its full stats, how much it earns over time and with multipliers, how fast it pays for itself compared with other Secret brainrots, cheaper or stronger alternatives, how to get it, and how to keep it from being stolen. All numbers are base values before rebirth bonuses, mutations or traits.

Extinct Matteo stats

How much does Extinct Matteo make?

The table shows how much cash Extinct Matteo generates over common play sessions at its base rate. Steal a Brainrot pays income every second while the brainrot sits on a pad in your base, so longer sessions add up quickly, especially for higher rarities.

In one hour, Extinct Matteo earns about 16.1 times its own price. That is a very fast return, so buying it early in a session is almost always worth it.

How brainrot income works

Each brainrot standing on a pad in your base adds its income to a collector that fills every second. Walk over or press the collect button to move that cash into your wallet, then spend it on more brainrots, upgrades or rebirths. Income only builds while the brainrot is in your base, so a stolen brainrot stops earning for you immediately and starts earning for the thief. That is why defence matters as much as buying: protecting Extinct Matteo keeps its 625K per second flowing.

Extinct Matteo income with multipliers

Base income is only the starting point. Rebirths, mutations, traits and limited events can multiply what a brainrot earns, and the effects stack in game. Use this table to estimate Extinct Matteo with common multipliers, then check exact bonuses in your own game, because multiplier values change with updates.

For your own numbers, open the Steal a Brainrot income calculator and enter Extinct Matteo with your multiplier.

Is Extinct Matteo worth it?

Compared with the rest of its rarity, Extinct Matteo pays back at about the same speed as a typical Secret brainrot, so it is a fair, average buy. The median Secret brainrot costs 800M, earns 4M per second and pays back in about 4 minutes. Extinct Matteo costs less than that median and earns less.

Value is not the only thing that matters. Your base has a limited number of pads, so in the long run the brainrots with the highest income per second win, even if they took longer to pay back. A good rule is to buy fast-payback brainrots early to build cash, then replace them with the highest earners you can afford, and sell or swap the weakest pad whenever you upgrade.

Where Extinct Matteo fits in your progression

Extinct Matteo is a late-game brainrot. Saving for it takes a strong base and usually several rebirths, and owning it makes your base a priority target for thieves. Late-game brainrots are where income really explodes, so each one you add can matter more than several lower-rarity pads combined. Protect it carefully, use multipliers to get the most from it, and only replace it with Secret or OG brainrots.

Rebirths reset your cash and brainrots in exchange for permanent bonuses, and some rebirths require you to own specific brainrots. Before you rebirth, check whether Extinct Matteo is needed for your next one, and plan purchases so the brainrots you buy now also help you meet the next requirement.

How to get Extinct Matteo

Extinct Matteo appears on the red conveyor belt in the middle of the map. When it rolls past, walk up to it and buy it for 140M before another player does; it then walks to an empty pad in your base. You can also steal Extinct Matteo from another player whose base is unlocked, carrying it back to your own base without getting hit.

About the Secret rarity

Secret brainrots are the rarest regular spawns, with the highest prices and income in the game apart from the OG tier. They appear extremely rarely on the conveyor, and many also come from events, admin abuse, fusing or lucky blocks. Expect intense competition and frequent steal attempts. A single Secret can out-earn an entire base of lower rarities, which is why late-game players hunt them.

Rarity order from lowest to highest: Common, Rare, Epic, Legendary, Mythic, Brainrot God, Secret and OG. See the rarities explained guide for the full breakdown.

How to protect Extinct Matteo from thieves

Every brainrot in your base can be stolen, and higher-value ones attract the most attention. Lock your base whenever you leave it: the lock is active for 30 seconds when you join, and after that you can lock it for 60 seconds plus 10 seconds for each rebirth. Stay near your base when the lock is about to run out, and keep your most valuable brainrots on the pads farthest from the entrance so thieves need more time to grab them.

If someone does steal Extinct Matteo, chase them. A player carrying a stolen brainrot moves more slowly, cannot use items and triggers an alert, and a single hit sends the brainrot straight back to your base. Using speed upgrades and staying in servers with fewer players also helps. For more defence tips, read the Steal a Brainrot hub.
