A rebirth in Steal a Brainrot is a trade: you give up every brainrot on your floor and your entire cash balance, and you get permanent bonuses that apply to everything you earn afterwards. The whole decision is whether what you give up is worth less than what you keep.
What a rebirth gives you
Each rebirth grants four permanent bonuses, and they stack across all 19:
| Bonus | Amount per rebirth | Why it matters |
|---|---|---|
| Brainrot slot | +1 | One more income stream per floor, forever |
| Base lock time | +10 seconds | Starts at 60s, so rebirth 6 is a 120s lock |
| Money multiplier | +1 | Applies to every brainrot you will ever own |
| New items | Unlocks | Gear and machines gated behind rebirth count |
Two of these compound. A slot is worth more the better your average unit, and the multiplier is worth more the bigger your floor. The lock time is the quiet one: at 60 seconds you cannot shop and defend at the same time, and at 120 seconds you can.
What it costs
Rebirth 1 costs $500K plus a Trippi Troppi and a Gangster Footera, both Rares that come off the Red Carpet. That is the only rebirth cost the sources we read publish as a complete figure.
What is known about the rest: there are 19 rebirths, and every one of them asks for specific brainrots by name, not just cash. That is the part that catches people. The cash you can grind; the brainrot you may have sold last week.
So the operating rule is: before you sell anything, check whether a later rebirth needs it. Cheap-looking Rares like the Trippi Troppi are exactly the kind of thing players dump for slot space and then spend a day re-buying.
What a rebirth does not take
- Items. They survive. This is why the wiki’s advice is to rebirth rather than hoard.
- Your rebirth count. Obviously, but it means the bonuses are strictly cumulative.
- Your floors. A second floor unlocks at rebirth 2 and a third at rebirth 10, and they stay unlocked.
What it does take: every brainrot on your base and all of your cash. You restart the shopping phase from a near-empty floor with a better multiplier, which is the entire point.
The timing maths
The multiplier is permanent, so the cost of waiting is not zero. If your floor earns $50K/s and you delay a rebirth by an hour, you have earned $180M at the old multiplier. The rebirth would have made that same hour worth more. In general:
Rebirth as soon as you can pay the cash and replace the required brainrots cheaply.
The exception is the one that bites: if the required brainrots are also your best earners, rebirthing means rebuilding your income from nothing, and the multiplier has to pay back that gap before it pays you anything. In that case, buy a replacement for your top earner first, then rebirth.
A simple test before you press it:
- Can I afford the cash requirement and still have shopping money left?
- Are the required brainrots replaceable from the carpet today, or are they fuse-only?
- Will my floor still earn something after the wipe?
Three yeses means rebirth now. Any no means fix that first.
Floors: where to put what
The floor unlock schedule is the most underrated part of the system:
| Rebirth | Unlock | Access |
|---|---|---|
| 2nd | Second floor | Outside stairs |
| 10th | Third floor | Inside ladder |
Higher floors are harder to steal from, which is the whole reason to care. Your best units belong on the top floor you have, and your cheap churn belongs on the ground floor where a thief will grab it and leave.
There is a trade-off in the access route. A second floor reached by outside stairs is a visible climb; a third floor reached by an inside ladder is behind your laser gate. That ordering is not an accident, and it is why rebirth 10 is a bigger jump than the numbers suggest.
Rebirth checklist
- Cash requirement met, with shopping money left over
- Required brainrots owned and not your only earners
- Next rebirth’s brainrot list read before selling anything
- Best units moved to the highest floor you have
- Traits and mutations on units you are about to lose — check before you spend them
That last one is the expensive mistake. Mutations and traits are attached to the brainrot, and a rebirth consumes the brainrot. Do not put a Rainbow mutation on a unit you are about to trade in for a rebirth.
