How to Fill Your Base
Pedestal layout, slot upgrades, and the income stack every Base should run.
Your Base is where every Brainrot you pull eventually lives. Filling it efficiently is the difference between grinding for hours and printing passive cash while you sleep. This guide covers the slot layout, pedestal upgrades, and income stacking strategy that experienced players use to keep their Base productive across Rebirths.
Why the Base Matters
Every empty pedestal is lost income. The fastest players in Brainblast a Lucky Block always have every slot filled, even when the unit on it is a low-rarity Brainrot. Slots are a long-term investment: the unit on them today is not the unit you will run tomorrow, but the slot itself is permanent.
Pedestal Layout
Most players should arrange pedestals like this:
- Top row — Highest-income Brainrots. These are your S-tier and A-tier units.
- Middle row — B-tier and lower-A-tier fillers. Rotate these as you unlock upgrades.
- Bottom row — Event Brainrots and C-tier placeholders. Replace these first as you progress.
The exact layout does not affect income, but it does affect how easily you can swap units in and out. Keep your highest earners near the top so they are easy to find.
Pedestal Upgrades
Pedestal upgrades unlock more slots for your Base. The cost curve is steep, but each slot is a permanent multiplier on your passive income. The upgrade priorities are:
- First expansion — Always worth it. The slot pays for itself within hours.
- Second expansion — Worth it once your income exceeds your upgrade spending.
- Third expansion and beyond — Plan around your next Rebirth. Slots unlocked late-game benefit from the cash multiplier.
Income Stacking Strategy
The income stack your Base runs should look like this, from highest earner to lowest:
- S-tier in every slot you can afford to fill.
- A-tier as the fallback until you unlock more S-tier.
- B-tier for slots you cannot yet upgrade.
- C-tier only as a temporary bridge until you swap them out.
The Tier List breaks down each tier in detail. Use the Brain Power Calculator to model your upgrade cost before committing coins.
Common Mistakes
- Leaving pedestals empty. Every empty slot is lost income.
- Upgrading C-tier Brainrots. Spend coins on Speed and Brain Power first.
- Selling event Brainrots. Event units usually have a hidden multiplier — verify with the Tier List before selling.
