Expired Codes Archive

Promo codes in Merge a Black Hole do not last forever. XAF Games disables strings during Sunday weekly updates, after limited-time events, or when balance changes make old rewards obsolete. This archive documents codes that no longer work so you stop wasting time typing them — and so you know where to find replacements on the working codes hub.

Roblox merge games rotate codes quickly. Community Discord servers and outdated YouTube videos often repost expired strings days or weeks after shutdown. Always test against our active list first: MERGE (1,000 Cash) and FREESTARS (2 Stars) are the current verified codes redeemed via the Codes button top-right.

Why codes expire

Developers retire codes for several predictable reasons:

Balance patches — A code granting 10,000 Cash might break early-game pacing after merge costs drop in a Sunday patch. XAF Games removes or replaces it.

Event endings — Holiday or milestone codes typically expire when the event UI disappears, even if the string still circulates online.

Abuse prevention — Leaked or datamined codes get disabled once too many alt accounts farm them.

Rebranding — When the game updates thumbnails, descriptions, or major systems, old launch codes are often cleared simultaneously.

Understanding expiration helps you set expectations: if a code failed right after a Sunday update, it probably moved here — not to a hidden “secret” menu.

Recently expired codes

The table below tracks codes confirmed dead after testing on live servers. Rewards are recorded for historical reference only.

Code	Former reward	Status	Notes
LAUNCH	500 Cash	Expired	Original release celebration code
BLACKHOLE	1 Star	Expired	Disabled post-launch balance pass
XAFTHANKS	750 Cash	Expired	Developer appreciation event
SUNDAY	1 Star	Expired	Weekly update teaser — one-time event
UPDATE1	500 Cash + 1 Star	Expired	First major Sunday patch reward

If any code above unexpectedly works again, XAF Games re-enabled it temporarily — report it on the working codes page so we can re-verify. Reactivations are rare.

Codes that were never official

Some strings spread by fan sites but never existed in the live code table. Common examples include generic phrases like FREEROBUX, ADMIN, or INFINITYSTARS. These fail with “invalid code” because they were never published — not because you typed them wrong.

Do not trust “code generator” websites claiming to produce unlimited Stars. Merge a Black Hole only accepts codes through the in-game redemption field. Anything asking for your password is a scam. Stick to official links and this wiki’s verified lists.

How we verify expiration

After each Sunday update from XAF Games, we:

1. Re-test every code on the working codes hub.
2. Attempt redemption on a secondary account for codes rumored expired.
3. Move failed one-time codes into this archive with the patch date in our internal notes.
4. Cross-check the updates page for patch notes mentioning promo changes.

A code lands here only after multiple failed attempts across rejoined servers — not from a single typo.

What to do when your code expires

Stop retrying the same string — Roblox will keep returning invalid or expired messages.

Switch to active codes — Redeem MERGE and FREESTARS from the working list if you have not already.

Follow update day — New codes often appear Sunday evening or Monday after maintenance. Bookmark the codes hub.

Spend currencies wisely — Expired code hunts waste time better spent merging. Use the cash income tier list to grow offline earnings without promos.

Expired vs. already redeemed

Two different errors confuse players:

• Expired / Invalid — The code is dead globally. No account can claim it.
• Already redeemed — The code still works for others, but you used it before. Do not archive these as expired; create a second account if you want to test, or ask a friend to verify.

Keep a personal note of codes you claimed so you do not mistake “already redeemed” for expiration.

Historical context for Merge a Black Hole

Merge a Black Hole launched as XAF Games’ entry into the Roblox merge genre — combine black holes, earn Cash offline, raid bases, lock your base, spend Stars in the Star Shop, and rebirth for multipliers. Early launch codes like LAUNCH helped players afford first-tier holes before offline income scaled. As the meta matured and raiding became more competitive, those rewards were retired in favor of smaller, balanced codes like MERGE.

Reading expired entries helps long-time players remember event timelines and helps new players avoid junk lists copied from outdated videos.
