FAQ
Frequently Asked Questions
What does the base shield do?
The base shield temporarily protects your black holes and cash from other players' raids. Upgrading it extends the timer from a few seconds up to several minutes, and you can toggle PvP on or off.
Does Merge a Black Hole give passive income offline?
Yes. Your black holes generate cash every second, including while you are offline. Higher-tier holes produce significantly more cash, which is why merging up and upgrading spawn tier matters.
What are spawn cap and spawn tier?
Spawn cap limits how many black holes can exist on your base at once, while spawn tier sets the minimum level of newly spawned holes. Upgrading spawn tier means new holes spawn at level 2, 4, 8, or higher instead of level 1.
Is auto-merge worth it?
Auto-merge automatically combines identical black holes so you do not have to drag manually. It is available via a Robux gamepass or a free version that triggers every few minutes.
