How to Redeem Codes

Redeeming promo codes in Merge a Black Hole is straightforward once you know where XAF Games placed the menu. This guide walks through every step — from joining the experience to confirming Cash and Stars hit your account — plus fixes for the errors players see most often after Sunday weekly updates.

Whether you are claiming MERGE for 1,000 Cash or FREESTARS for 2 Stars, the process is identical. Codes never require Robux, external websites, or third-party login pages. Everything happens inside the Roblox client through the official redemption UI.

Before you redeem

Make sure you are playing the real Merge a Black Hole experience published by XAF Games. Fan copies and outdated place IDs sometimes circulate in search results; rewards only apply on the official game. If you just updated Roblox or the game patched on Sunday, fully rejoin the experience so the Codes menu loads the latest server version.

Copy codes from our working codes hub rather than retyping from memory. Roblox code fields reject extra spaces, and many codes use mixed capitalization. MERGE and FREESTARS must match exactly.

Step-by-step redemption

Step 1: Launch the game

Open Roblox and enter Merge a Black Hole. Wait until your base loads, the merge area is visible, and HUD elements such as Cash balance appear. Redeeming during the loading screen occasionally fails silently — give the world five to ten seconds to finish spawning assets.

Step 2: Open the Codes menu

Look at the top-right corner of the screen. You should see a Codes button alongside other UI shortcuts. Tap or click Codes to open a text input panel. On mobile, the button may sit near settings or shop icons depending on your screen aspect ratio; it remains on the right side of the HUD in current builds.

If you cannot find the button after a patch, check the updates page — XAF Games occasionally moves UI elements during Sunday maintenance. Rejoining fixes most missing-button reports.

Step 3: Enter the code

Type or paste the promo string into the box. Start with MERGE if you want Cash, or FREESTARS if you want Stars. Do not add quotation marks or hashtags. Press Redeem (or the equivalent confirm button on console).

Step 4: Confirm rewards

A success notification should appear on screen. Verify rewards manually:

• MERGE — Cash balance increases by 1,000.
• FREESTARS — Star total increases by 2.

Stars may display near the Star Shop icon rather than next to Cash. Open the Star Shop briefly to refresh the UI if numbers look stale.

Step 5: Redeem remaining codes

Each code is one-time per account. After MERGE succeeds, repeat the process for FREESTARS. When both are claimed, you are done until XAF Games publishes new strings — watch the working codes list for additions.

Platform-specific notes

PC / Mac: Click Codes top-right, paste with Ctrl+V (Cmd+V on Mac), press Redeem.

Mobile (iOS / Android): Tap Codes, long-press the field to paste if you copied from the wiki, then tap Redeem. Mobile keyboards sometimes auto-correct capitalization — disable autocorrect for code entry.

Console (Xbox): Use the on-screen keyboard via the Codes button. Enter letters carefully; console input lacks paste in some Roblox builds.

Troubleshooting failed redemptions

“Invalid code” or “Code expired” — The string is wrong or disabled. Compare spelling on the codes hub. Expired codes live on the expired archive.

“Already redeemed” — You claimed it on this account before. Codes cannot be reused.

No message, no reward — Rejoin the server. If still broken after a Sunday update, wait for a hotfix; developers sometimes redeploy code tables hours after the initial patch.

Codes button missing — Update Roblox, rejoin, or restart the app. Rare UI bugs clear after a fresh session.

Rewards seem lower than expected — Some boosts modify displayed gains. Note your balance before and after redemption rather than trusting floating text alone.

Best time to redeem for progression

Redeem MERGE before a long merge session or offline period so the extra Cash participates in purchases and merge chains immediately. Redeem FREESTARS when you know which Star Shop item you want — consult the tier list overview before spending Stars on cosmetic picks that do not help income or raiding.

Players planning a rebirth should read rebirth guidance in the getting started guide first. If rebirth resets currencies, timing code redemption after rebirth may align better with your build — verify in-game because rebirth rules change in Sunday patches.

Security reminders

Never enter Roblox credentials on external “code generator” sites. Real codes flow only through the in-game Codes button. Report scam links to Roblox and stick to official links for announcements.

Automation tools exist for merge and rebirth loops; if you use them, redeem codes manually first so rewards are not missed while scripts run. See the scripts hub for feature overviews — manual redemption always stays safest for account standing.
