Why aren't my Undertale: Arena codes working?

The most common reason for an invalid code is that the user entered it incorrectly. Undertale: Arena codes are case-sensitive and require all the necessary punctuation (exclamation points are common in Roblox codes). To avoid typos, copy and paste the code directly from our page into the game, instead of entering it manually.

The game will tell you if you have already used a code. If you are sure you entered the code correctly and it doesn't say "Already Redeemed" when you submit it, then it has likely expired. If this happens, be sure to leave us a comment so we can investigate the issue and update the page!
