Lucky Block Rush Base Upgrades

Base upgrades expand your Brainrot slot capacity and improve passive income potential. More slots means more simultaneous Brainrot income.

Slot Expansion

Purchase base slot upgrades when income supports the cost. Each new slot should be filled immediately with your best available Brainrot. Empty slots are wasted income.

Upgrade Priority

Fill existing slots before expanding. Upgrade Brainrot levels before buying new slots. Expand slots before buying expensive endgame Dummies.

Income Impact

Doubling base slots roughly doubles offline income if filled with equivalent Brainrots. See Offline Income Build.
