How to redeem Undertale Dungeons codes

We have not confirmed the exact code screen for Undertale Dungeons yet — none of the guide sources we track spells it out. Across the 65 fighting & rpg games where we have confirmed it, the code box sits behind a Menu panel 31% of the time, and the Settings or gear icon 20%. Start there:

Launch Undertale Dungeons in Roblox.
Open the in-game Codes menu (often a Settings or social-media icon).
Enter (type or paste) a code from the list above exactly as shown, then confirm to claim the reward.

Why isn't my Undertale Dungeons code working?

The usual reasons a Undertale Dungeons code fails, in order of likelihood:

It just expired. Codes can stop working without notice — if a code fails, it may have expired since our last check. Codes the majority of sources report as dead move to the expired list above.
Typo, casing or spaces. All 6 Undertale Dungeons codes we have on file are uppercase — they have to match exactly, character for character (HEYNOELLECHECKOUTMYNEWCUT is a real one from this page). Use the Copy button instead of typing by hand, and watch for trailing spaces.
Old server. After a game update, some codes only register on fresh servers — leave and rejoin Undertale Dungeons, then try again.
Limited or one-time codes. Milestone codes (noted in their status details in the table) often die once their milestone passes. Every code can only be redeemed once per account.

How to get more Undertale Dungeons codes

New codes for Undertale Dungeons usually drop with game updates, in-game events and player milestones. The developer posts them on the game's official Roblox page and community channels, and Roblox guide sites pick them up within hours. We cross-check those sources for new Undertale Dungeons codes every day and archive what stops working — so bookmarking this page is the low-effort way to catch new codes without chasing every channel.

Frequently asked questions

Do Undertale Dungeons codes still work in August 2026?

As of August 2026, 6 codes for Undertale Dungeons are listed as working across the independent sources we track — new finds and disputed codes carry their own labels. Codes can expire at any time without notice, so check the last-updated stamp above — codes the majority of sources report expired move to the archived list below.

How often is the Undertale Dungeons codes list updated?

Every day. We re-read all 2 independent Undertale Dungeons code sources we track once a day, then rebuild this page from what changed — that is why the timestamp above moves even on days when no new code appears.

Why don't you say the codes are "verified" or "tested"?

Because we have not sat down and redeemed every one of them in-game, and we are not going to pretend otherwise. What we can show you is the evidence behind each Undertale Dungeons code: each code carries the number of independent sources reporting it. Codes backed by only one source are labelled as such instead of being dressed up.

What do Undertale Dungeons codes give you?

Recent Undertale Dungeons codes have granted rewards like 20 Soul Essence and 25 Soul Essence. The table above shows the exact reward next to every working code.
