How to Rebirth for Permanent Income
Rebirth timing, multiplier stacking, and the safe way to chain resets.
Rebirth is the prestige system at the heart of Brainblast a Lucky Block. You trade your current Brain Power for a permanent cash multiplier that compounds on every drop, every Base slot, and every future Rebirth. This guide explains when to Rebirth, how the multiplier stacks, and the safe way to chain resets without losing the progress you worked for.
What Rebirth Does
When you Rebirth, your current Brain Power resets to zero but you keep your Base, your Brainrots, your Speed upgrades, and your coins. In exchange, your cash multiplier goes up permanently. The multiplier stacks across Rebirths, so chaining resets is the fastest way to scale your income.
When to Rebirth
The rule of thumb experienced players use is:
- Rebirth 1 — As soon as you can afford it. The reset cost is negligible, the multiplier pays back within minutes.
- Rebirth 2-4 — When the next reset pays for itself within an hour. Use the Rebirth ROI tool to model your exact timing.
- Rebirth 5+ — When your income exceeds your upgrade spending and you can rebuild Brain Power in under an hour.
Do not skip a Rebirth because you are attached to your current Brain Power. The multiplier compounds for the rest of your account, so a delayed Rebirth is permanent lost income.
The Cash Multiplier Stack
Every Rebirth adds to your permanent multiplier. The compounding math looks like this:
| Rebirth # | Multiplier |
|---|---|
| 1 | x2 |
| 2 | x3 |
| 3 | x4 |
| 4 | x5 |
| 5 | x6 |
| 6 | x7 |
| 7 | x8 |
| 8 | x9 |
| 9 | x10 |
| 10+ | x11 and beyond |
By Rebirth 5, every Brainrot in your Base earns five times its listed income. By Rebirth 8, that figure is nine times. The compounding effect is the single biggest reason experienced players push Rebirth as fast as possible.
The Safe Way to Chain Resets
- Redeem every active code before you reset — codes stack across Rebirths.
- Fill your Base with at least three Mythic units so the income stream survives the reset.
- Upgrade Speed so you can rebuild Brain Power in the highest-rarity zones immediately.
- Confirm the cash multiplier is active before starting your new grind.
