Murder Mystery DUELS pits you against other players in fast, round-based matches where staying alive and outsmarting the murderer matters more than grinding. Codes here hand you free Cash and knife skins you’d otherwise have to earn or buy, so it’s worth checking in and redeeming what’s active before it disappears.

How to redeem codes in Murder Mystery DUELS

Redeeming codes doesn’t happen through a separate codes menu here, it’s tucked inside the Shop. Follow these steps once you’re in the game.

Open Murder Mystery DUELS on Roblox and wait for your lobby to load in.
Tap the Shop button on the left side of your screen.
Find the Type code text box and enter a code exactly as it’s written above. Copy-paste it if you can, since a stray lowercase letter or extra space will make it fail.
Hit Submit. You’ll know it worked when your Cash total jumps up right away, and if the code includes a Knife Skin, it lands in your inventory instantly too.

This one no longer works, so don’t waste a redemption attempt on it.

How to get more Murder Mystery DUELS codes

New codes for Murder Mystery DUELS tend to show up around updates and milestones, so your best bet is to keep an eye on the game’s own channels rather than guessing. The developer’s Discord server is where announcements land first, and joining the game’s Roblox community puts you in front of the same updates. You can also jump straight into the Murder Mystery DUELS experience page on Roblox to check for any in-game announcements tied to a fresh code drop.

Why didn’t my code work?

Double-check your spelling and capitalization first, since the Type code box treats codes as case-sensitive. If the code is spelled correctly and it’s still not going through, it’s likely expired.


Bookmark this list and swing by whenever you’re stocking up on Cash or hunting for a new knife skin, since codes here come and go without much warning.
