Working Merge a Black Hole Codes

Merge a Black Hole is a Roblox merge simulator from XAF Games where you combine black holes, earn Cash while offline, Raid other players’ bases, and spend Stars in the Star Shop. Promo codes are one of the fastest ways to jump-start progression without spending Robux, and this page tracks every code we have confirmed as working.

Last verified: July 29, 2026 — four codes remain active on live servers. UPDATE3 and 3SPINS are new drops from the late-July patch cycle; MERGE and FREESTARS still work. Destructoid (July 27) and Pocket Gamer (July 28) re-confirmed these strings, and we re-tested all four on July 29, 2026. Re-check after the next Sunday patch from XAF Games and watch the updates hub for same-day code drops.

What codes fund in July 2026

Cash from MERGE helps raise spawn rate and hole cap — the limits on how fast black holes generate and how many you can field. Stars from UPDATE3 and FREESTARS (7 Stars total if you redeem both) feed the Cosmic Spin wheel via Ticket exchanges and abilities such as Hole Surge, Mystery Meteor, and Hole Spawn multipliers. 3SPINS grants 3 Spin Tickets for Cosmic Spin directly — three free wheel pulls without spending Stars. Read the Cosmic Spin guide for spending priorities before you burn Stars on cosmetics.

XAF Games typically ships balance changes and new content on Sundays, and codes sometimes arrive alongside those patches or through official social channels. We re-test codes after each weekly update so you are not wasting time typing expired strings.

Working codes (verified)

Code	Reward	Status
UPDATE3	5 Stars	Active (NEW)
3SPINS	3 Spin Tickets	Active (NEW)
MERGE	1,000 Cash	Active
FREESTARS	2 Stars	Active

Copy each code exactly as shown — codes are case-sensitive in most Roblox experiences, and a single extra space will cause redemption to fail.

What UPDATE3 gives you

UPDATE3 awards 5 Stars, the largest Star bundle in the current rotation. Five Stars can buy multiple Cosmic Spin Tickets or a meaningful Star Shop row — pair UPDATE3 with FREESTARS for 7 Stars before you spend anything. Redeem UPDATE3 early in a session so Star totals refresh on the HUD before you open the Star Shop or spin wheel.

What 3SPINS gives you

3SPINS delivers 3 Spin Tickets for the Cosmic Spin wheel — no Star exchange required. Tickets are consumed one per spin, so you get three independent pulls at whatever prizes the current Sunday rotation offers. This is ideal when a boosted-odds banner is live; see the Cosmic Spin guide for when to spin versus saving Stars for guaranteed Star Shop upgrades.

What MERGE gives you

MERGE grants 1,000 Cash, which is meaningful in the first hour of play. Cash fuels black hole purchases, base upgrades, and early merge chains before your offline income ramps up. If you are saving for a specific hole tier or trying to unlock merge slots faster, redeem MERGE before your next merge session so the bonus Cash is included in your balance calculations.

What FREESTARS gives you

FREESTARS awards 2 Stars, stacking with UPDATE3 for 7 Stars total. Stars unlock powerful boosts, cosmetic items, and quality-of-life upgrades that Cash alone cannot buy. Even two Stars matter when you are pushing toward late-game raiding loadouts — every Star counts alongside rebirth bonuses and weekly events.

How to redeem codes in Merge a Black Hole

Redemption takes less than thirty seconds once you know where the menu lives:

1. Launch Merge a Black Hole on Roblox.
2. Look at the top-right corner of the screen for the Codes button.
3. Tap Codes to open the redemption text box.
4. Type or paste each code — we suggest UPDATE3, 3SPINS, MERGE, then FREESTARS.
5. Press Redeem after each entry and check your Cash, Stars, or Spin Ticket balance.

If you need screenshots or troubleshooting for failed redemptions, read our full how to redeem codes guide. Common fixes include rejoining the server after a Sunday update and making sure you have not already claimed a one-time code on that account.

When to check for new codes

Because XAF Games updates on Sundays, bookmark this page and revisit after each weekly patch. Developers often drop limited-time codes during milestones, holidays, or when a major merge tier is added. We also cross-reference the game updates tracker so you know when the game files changed even if no new code was announced publicly.

Expired codes move to the expired codes archive — do not delete them from your notes until you confirm they fail in-game, since some community lists repost old strings that no longer work.

How codes fit into your progression route

Codes are a supplement, not a replacement for core loops. After redeeming all four active codes, spend MERGE Cash on merge chains that match our cash income tier list recommendations, Lock your base before going offline, and route UPDATE3/FREESTARS Stars toward Star Shop items that improve long-term income. Use 3SPINS Tickets during boosted Cosmic Spin windows rather than on a quiet weekday wheel.

Players who Rebirth regularly should redeem codes after a rebirth if the rewards scale with multipliers — check the in-game popup to see final amounts. Raiders will want Stars invested in defensive upgrades first; see the raiding tier list for PvP priorities.

Code etiquette and account safety

Only redeem codes published through official XAF Games channels or this wiki after verification. Never share your Roblox password, and ignore DMs promising “infinite Stars” or fake code generators — those are scams. Legitimate codes always go through the in-game Codes button; there is no external website required.

For broader mechanics — merging, offline Cash, base locks, and rebirth timing — start with the getting started guide and the merge guide. Those pages explain how Cash and Stars interact so you know the best moment to redeem each code.
