Expired codes
None— No expired Knife Arena codes are known at this time.
Why codes might not work
- The code has expired and is no longer active, even if it used to work earlier.
- There is a typo in the code, or extra spaces were added; Knife Arena codes are case-sensitive and must match exactly.
- The code was already redeemed on your Roblox account, so it cannot be claimed again.
- The Roblox client or Knife Arena session needs to be refreshed; close the game, reopen it, and try redeeming the code once more.
