Expired Knife VS Gun DUELS Codes
Retired promos, milestone strings, and how expiration works.
Every Knife VS Gun DUELS promo code eventually stops working. Developers disable old strings to prevent unlimited economy inflation and to encourage players to engage with new milestones. This page archives expired codes so you do not waste time retyping dead promos, explains how expiration works in Roblox experiences like this one, and shows where to find replacements before they disappear too.
Knife VS Gun DUELS is a 1v1 pad duel game on Roblox where you fight with knives or guns, earn coins for wins, build streaks, and climb leaderboards. Codes are a bonus layer on top of duel income — not a substitute for learning How to Earn Coins or How to Win Duels.
How codes expire in this game
When a code expires, the ENTER CODE field in Inventory returns an invalid or already-redeemed style message with no reward. Expiration is controlled server-side by the Knife Gun Duels team. There is no countdown timer in the UI telling you when a code will die — you discover expiration only by trying to redeem or by reading update posts.
Common reasons codes retire:
- Milestone completed — Visit-count codes like
10MVISITSmay stay active for months, but older celebration strings from earlier milestones often shut off when a newer one replaces them. - Event ended — Launch-week promos typically have the shortest lifespan.
- Economy balance — High coin grants get removed when they skew trading or unbox prices.
- Abuse prevention — Leaked or widely bot-farmed codes get disabled early.
There is no official Trello listing historical codes. This wiki, community Discord, and the in-game Code Board near leaderboards are the reliable sources for what still works today.
Expired code examples
These strings are no longer valid as of our last review. Do not expect rewards if you try them — keep them as historical reference only.
| Code | Reported reward (when active) | Notes |
|---|---|---|
THANKYOU49800 | Coins (milestone thank-you) | Retired after early visit celebrations |
SECRETHAT | Cosmetic or coin bonus | Limited-time social promo |
LAUNCH | Launch-week coins | Tied to 2025-01-19 release window |
THANKYOU100M | Large coin grant | Milestone code; replaced by newer visit strings |
If a YouTube comment or old blog still lists these, treat the post as outdated. Always cross-check the active codes table before redeeming.
How to tell a code is expired vs broken
Expired — Correct spelling, never worked on your account, and absent from the Code Board and Discord pin. Other players confirm the same invalid message.
Typo — One wrong character. Re-copy from the Codes hub and try again.
Already redeemed — Worked once on your account; alts might still claim it if the code were active, but yours shows used.
Wrong game — Copycat experiences mimic popular duel games. Confirm Place ID 120700541929930 and creator Knife Gun Duels before blaming expiration.
When unsure, ask in Discord with the exact message Roblox showed. Screenshots help moderators confirm retirement quickly.
What to do when your favorite code dies
First, redeem any still-active strings immediately. New accounts should burn through the full active list in one session via How to Redeem Codes before grinding duels.
Second, shift focus to repeatable income. Win streaks, daily play, and smart unboxes outperform one-time codes over a week of play. See How to Earn Coins for priority order.
Third, watch for replacement milestone codes. When player counts hit new thresholds, developers often ship fresh strings similar to 500KVISITS. The pattern repeats: celebrate, release code, retire older thank-you variants like THANKYOU49800.
Fourth, use Tools on this wiki if you track unbox ROI — knowing when to open cases matters more after cheap coin codes expire.
Why developers retire codes instead of leaving them forever
Unlimited redemptions would flood the economy with coins and tradable items. Trading and leaderboard chase depend on scarcity and skill expression. If every account could forever claim THANKYOU100M, rare skins would lose value and streak motivation would drop.
Limited-time codes also reward players who stay engaged with the community — Discord members see announcements first and redeem before Twitter reposts spread the string to millions.
That design can frustrate returning players who miss a window. Bookmark the Codes hub and enable Discord notifications if you take long breaks.
Avoiding fake “expired code revival” scams
Scam sites claim to reactivate expired codes or generate unlimited coins. They ask for Roblox passwords or Robux payments. Real expired codes never come back unless the developer explicitly re-enables them during a special event — rare and always announced officially.
Never download “code unlocker” executors. They violate Roblox Terms of Use and risk account bans. Stick to legitimate redemption steps and duel earnings.
Tracking code history on this wiki
When we confirm a code expired, we remove it from the active table on the Codes hub and document it here with the last known reward. If the team re-enables a code during an anniversary event, we move it back to active with a note.
Report discrepancies if you successfully redeem a code listed as expired — games sometimes turn promos back on briefly for weekends. We update fast when multiple readers confirm.

Frequently Asked Questions
Quick answers about duels, codes, streaks, and wiki pages.
Does THANKYOU49800 still work?
No. THANKYOU49800 is an expired milestone code. It no longer grants coins or items. Use the active list on the Codes hub instead.
Can expired codes come back?
Rarely. Developers sometimes re-enable a code for an anniversary, but there is no guarantee. Official announcements on Discord precede any revival.
Why does LAUNCH say invalid?
LAUNCH was a release-week promo tied to the January 2025 launch. Launch codes typically expire within weeks. It is archived as expired.
How do I know a code is active?
Check the Codes hub active table, the in-game Code Board near leaderboards, and Discord pins. If all three omit a string, assume it is expired.
What happened to SECRETHAT?
SECRETHAT was a limited social promo that has been disabled. It appears in old videos and comments but no longer redeems.
Is THANKYOU100M still worth trying?
No. THANKYOU100M was a large milestone coin code that has been retired. Newer visit milestones use different strings like 500KVISITS while active.
