Two working codes are live in Merge a Black Hole right now, and they hand out free stars and cash you can put to immediate use. If you've been grinding to push your hole cap higher or unlock a boost, these save you the wait. The game sits comfortably in the same casual-but-addictive corner of Roblox as Gossip Harbor: Merge Game, where small freebies compound into real progression advantages over time.

What the active codes actually give you
Here's the lowdown on what's redeemable right now:
Both codes are confirmed active as of July 23, 2026. The cash goes toward increasing your spawn rate and hole cap, which directly affects how fast your black holes grow and how much they earn passively. Stars are the premium-adjacent currency you spend on boosts, so getting 2 for free is the better pull of the two.
How to redeem codes in Merge a Black Hole
The process is straightforward once you know where to look:
- Launch Merge a Black Hole on Roblox
- Finish the tutorial (it's short)
- Open the shop menu on the left side of the screen
- Scroll all the way to the bottom
- Type or paste your code into the entry field
- Hit Redeem
No special permissions or account level required. The codes work on any Roblox account.
Before vs. after: what these rewards change
Without the codes, early progression in Merge a Black Hole leans on passive cash accumulation. Your black holes earn while you're offline, but the spawn rate cap limits how quickly things scale. The 1,000 cash from MERGE gives a noticeable early bump to that cap, letting your holes generate at a higher rate sooner than the default grind allows.
The 2 stars from FREESTARS matter more mid-game. Stars unlock boosts that accelerate merging speed or amplify earnings, and those boosts are the difference between a collection that grows at a steady pace and one that snowballs. Getting them without spending is a genuine head start.
The key here is redeeming both before either expires. Merge a Black Hole codes don't have published expiry dates, but Roblox game codes typically rotate without warning.
Where new codes come from
The developer drops new codes in the official Merge a Black Hole Discord server, specifically in the dedicated codes channel. Joining that server is the fastest way to catch codes before they expire. For players who'd rather not manage another Discord, checking back here works just as well since the list gets updated as codes rotate.
