New Redeemable Mugen Codes and Where to Find More (September 2025)

Want to speed up your journey to becoming the ultimate Demon or Demon Slayer in Roblox’s Mugen? Then check out these Mugen codes, which you can redeem for in-game rewards. You can redeem codes right off the bat, so whether you’re a new or old player, these codes are sure to come in handy.
Additionally, this guide will also teach you how to redeem the codes, where to find more as they come out, and how to earn Yen, the primary currency in Mugen.

Active Mugen Codes
The main rewards you get from Mugen promo codes are Normal Style Spins, Lucky Style Spins, and Yen.
You use Spin Styles to obtain a random fighting style. The difference between Normal and Lucky Style Spins is that Lucky Style Spins have a higher chance of granting you rarer fighting styles, which makes them better.
Note: Mugen is a little special when it comes to promo codes, because sometimes, expired codes can suddenly become active again. For example, from this list of active codes, “TESTING” and “SRRYSRRY” were once expired.
How To Redeem Mugen Codes

Here’s how you can redeem all of the available Mugen codes. Thankfully, it’s pretty easy!
- Tap or press the gift icon with the label “CODES” at the bottom of the screen.
- Type or paste your code in the Redemption Code field and hit “Redeem”. Your rewards will immediately be given to you.
Where Can You Find New Mugen Codes?
With Mugen promo codes expiring and returning all the time, it’s useful to redeem them as soon as they become active. You can tune in to these sources to ensure you’re up to date on all the active codes.
- Social Servers: Visit and keep up with the Mugen Discord server, which is the most reliable spot for codes.
- Gaming news and guide websites like Scrambly.io (you can earn money playing games using our site too!)
How To Get More Yen?
Yen is the main currency in Mugen. That being said, as of now, the only thing you can really spend it on is Normal Style Spins. Each Normal Style Spin costs 10,000 Yen, which is a lot, so you’re going to want to farm a ton of Yen to get the Styles you want.
As of the time of writing this article, there are only two known ways of reliably obtaining Yen:
- You can purchase Yen with Roblox.
- You can earn Yen by defeating other players.
How To Get Better at Fighting in Mugen?
If you’re a free-to-play (F2P) player, you’re going to want to get better at fighting other players to earn Yen. Here’s some advice that’ll quickly set you apart from other new players:
- Use the lock on ability (middle mouse button on PC) to keep track of any player you’re fighting. Mugen battles are incredibly fast-paced, so it’s practically impossible to manually track your opponent.
- Always remember that you have infinite dashes (Q key on PC). You can spam it as much as you like without getting exhausted or requiring a long cooldown. Use dashes to either escape from engagements or chase down targets.
- Learn to use blocks and parries. Blocking (F key on PC), as the name implies, allows you to block enemy attacks. You can’t block forever though. Keep an eye on the orange bar that appears next to you when blocking, because when that bar empties, your guard gets broken, and you can’t block for a little while.
The blue bar that appears next to you when blocking is the parry bar. It slowly fills up when blocking, and once it’s full, it allows you to parry (F + Right Mouse Button) while you’re being attacked. Parrying breaks the enemy’s combo, allowing you to punish them with your own attacks.
- Once you’re in a fight, don’t disconnect or go back to the lobby. Doing so will deduct from your Yen count. So, you either fight until you win or lose, or you can run away by dashing without going back to the lobby. Your opponent is likely going to chase you down though, so fighting until one of you loses might just be the better option.
Expired Codes
This is a list of codes that have already expired and are currently unredeemable. As mentioned above, these codes can turn active at any time, so try some of them out every now and then, and maybe you’ll get lucky.
