How to Get the Second Floor
Base upgrades, extra pedestals, and when the second floor is worth buying.
Your Base is the long-term income engine in Brainblast a Lucky Block. Unlocking the second floor adds more pedestals so you can run more Brainrots at once — and more filled slots is the cleanest passive-income multiplier in the game.
This guide covers how the second floor fits into Base upgrades, when to buy it, and how it pairs with Rebirth and Brain Power training.
Why the Second Floor Matters
Every pedestal is a permanent income slot. Expanding to a second floor means:
- More slots for S-tier and A-tier Brainrots.
- Higher passive cash while you train Brain Power or chase deep zones.
- Less pressure to sell mid-tier units just because you ran out of space.
Empty pedestals still earn nothing. Unlocking the floor only pays off when you can fill the new slots quickly — see How to Fill Your Base for layout and stacking rules.
How to Unlock the Second Floor
The second floor is a Base upgrade, not a free Rebirth gift. In practice:
- Open your Base upgrade / pedestal expansion options.
- Buy the expansion that unlocks the upper floor / extra pedestal rows when you can afford it.
- Immediately place Brainrots on every new pedestal — even temporary fillers beat empty slots.
- Rotate better units in using the Tier List as your income ladder improves.
Exact coin costs shift with balance patches, so treat the buy as a priority decision against Brain Power and Speed rather than a fixed number you must hit on day one.
Cost and Priority Tips
- Buy the second floor when income can absorb it without stalling Brain Power training. If one expansion empties your wallet for hours, wait one more income cycle.
- Fill first floor first. A half-empty first floor plus a new second floor is worse than a full first floor and a delayed upgrade.
- Pair with Rebirth planning. Extra slots compound harder after a Rebirth multiplier. If you are one reset away from a big income jump, model it with the Rebirth guide and Rebirth ROI tool before dumping everything into floor upgrades.
- Do not starve Speed / Brain Power. Deep zones (including OMEGA) still need the training stack. Second floor is a passive multiplier, not a replacement for distance.
- Use new slots for high earners, not storage clutter. Park event or S-tier units upstairs if that keeps your highest income easy to manage.
After You Unlock It
- Fill every new pedestal the same session.
- Re-sort by income — top earners visible, placeholders last.
- Keep grinding Brain Power so the extra income funds the next upgrade cycle.
- Revisit the Tier List whenever you pull something better than your worst slot.

Frequently Asked Questions
Quick answers to the most common questions.
What does the Base second floor do?
It unlocks more pedestals so you can place additional Brainrots. More filled slots means higher passive income.
When should I buy the second floor?
When your current income can pay for the upgrade without stalling Brain Power and Speed training for a long stretch. Fill your existing pedestals first.
Does the second floor give free Brainrots?
No. It only adds slots. You still need to pull or keep Brainrots to fill them.
Should I upgrade the second floor before Rebirth?
Often yes if you can fill the slots — permanent slots keep paying after the reset. If the cost would block a high-ROI Rebirth, take the Rebirth first.
Is the second floor required for OMEGA?
Not required, but the extra passive income makes the Brain Power stack for deep zones much easier to fund.
