If you do not feel like hunting for new codes every day, you can let us do the work. We update this page the moment fresh codes appear, and we move the expired ones aside so nothing gets mixed up. Add it to your bookmarks and keep your run smooth.
Even seasoned shooters need a little help at times. If you want updates straight from the source, join the official Knife Arena Discord server. It is the only verified place where new codes are posted, and you will find them neatly listed in the ‘code’ channel. Scouring through the announcement to get the codes for Knife Arena can get tricky, so we suggest you stick to our list.
Why Are My Knife Arena Codes Not Working?
If your Knife Arena codes aren’t working, they may have expired or been entered incorrectly. Codes are case-sensitive, so double-check for typos, extra spaces, or incorrect characters. Another reason might be that you’ve already redeemed the code, as most can only be used once per account. If none of these apply, the developers may have disabled the code temporarily or replaced it with a new one.
When new Knife Arena codes arrive, the game usually pushes a fresh client update, so give the servers a moment to reset before you try anything. If you see an error while redeeming, look for small typing mistakes. The safest option is to copy the code directly from our list. Some codes run on strict timers, so if one stops working, it likely means it has already expired. Visit our page again and see if it has been moved to the expired section.
How to redeem codes step-by-step in Knife Arena
To redeem codes in Knife Arena, you need to use the in-game Settings menu; the process is the same for all current codes like freecase.
Step-by-step redemption
-
Open the game
-
Launch Knife Arena from Roblox and wait until you are in the main menu or lobby, not mid-match.
-
-
Open Settings (cog icon)
-
Click or tap the gear/cog / Settings button at the top-left corner of the screen to open the options menu.

-
Enter your code carefully
-
Type or paste an active code (for example, freecase) into the box labeled something like “Enter Code Here,” making sure there are no extra spaces and the capitalization matches exactly.

-
Confirm and get rewards
-
Click the Redeem button; if the code is valid and unused, your reward (such as a Release Case for a knife skin) is added to your account immediately.
-
If the code doesn’t work
-
A “Failed” or similar error usually means the code is expired, already redeemed on your account, or typed incorrectly; double-check spelling and remove extra spaces.
-
If it still fails, try restarting Roblox/Knife Arena and ensure you are using a currently active code from a recent code list or official community channel.
