Why Codes Might Not Work
Codes in Undertale Arena might fail because they are case sensitive and must be entered exactly, including punctuation. Copying and pasting helps avoid typos. If the game says a code is already redeemed, you’ve used it before. Some codes expire after a while, so if a code doesn’t work and isn’t marked as used, it’s likely expired.
