December 2025 reports listed different active MUGEN codes on December 6 and December 26, so treat them as dated snapshots rather than codes that all worked throughout the month. The currently documented Codes button is at the end of the action bar along the bottom of the screen; codes may expire, and the game is in beta.
MUGEN is a Roblox experience created by Pure Pure. Its place ID is 139598620873181, and its official listing describes it as being in beta, where bugs may occur.

December 26, 2025: later reported codes
A December 26 list reported the following codes as active:
| Code | Reported reward |
|---|---|
| MERRYCHRISTMAS | Lucky Spins, Regular Spins, and Yen |
| XMASEVE | Lucky Spins and Yen |
| INFINITYFIXES | Lucky Spins and Yen |
The source did not state exact reward quantities. The listed code is MERRYCHRISTMAS, without an exclamation mark. A later forum post used MERRYCHRISTMAS!, but available sources do not verify that spelling, so do not treat the two versions as interchangeable.

This was a user-generated claim, not an official developer confirmation. It is included for context only, not as a verified list. In particular, its MERRYCHRISTMAS! spelling differs from the December 26 listing.

How to redeem MUGEN codes
Current documentation places the Codes button at the end of the action bar along the bottom of the screen. To redeem a code:
- Launch MUGEN on Roblox.
- Click Codes at the end of the bottom action bar.
- Enter the code in the Enter Code field.
- Click Redeem.
The December 2025 instructions placed the Codes button on the left side of the screen, but that location is outdated in the current documentation. If you cannot find the button, check the bottom action bar. Do not redeem while in Combat mode; leave combat first.

What to do if a MUGEN code does not work
- Check capitalization. Codes are reported as case-sensitive, so match the published capitalization exactly.
- Remove extra spaces. Delete spaces before or after the code, especially if you pasted it.
- Check whether it expired. The December 6 and December 26 lists differed, showing that codes can change over time.
- Check whether you already redeemed it. Each code is reported as redeemable once per account.
- Leave Combat mode. The December 26 instructions warn against redeeming while in combat.
- Rejoin the experience. If rewards do not appear immediately, exit the code menu and rejoin MUGEN.
- Restart if the server is unstable. Exit and start the experience again before testing the code.

About the current official listing
The currently crawled Roblox listing displays 475KLIKES and says another code is planned at 500K likes. It does not provide a December 2025 release date or a reward amount for 475KLIKES, so do not describe it as a December 2025 code or assign it an unverified reward.
