If you searched for “Anime Mysterious code,” you are looking for redeem codes for the Roblox tower-defense game Anime Mysterious. The newest batch reported on October 16 is tied to the Halloween and Update 0.75 rollout. Two current code roundups list the same four strings, but describe their rewards only as “free rewards.” Because codes can be turned off without notice, treat them as reported codes and use the in-game response as the final check.
New Anime Mysterious codes for October 2026
| Code | Reported status | Rewards listed by current sources |
|---|---|---|
HAPPYHALLOWEEN | Reported new on October 16 | Free rewards; exact item counts were not published in the code lists we checked. |
IAMATOMIC | Reported new on October 16 | Free rewards; exact item counts were not published in the code lists we checked. |
UPDATE075 | Reported new on October 16 | Free rewards; exact item counts were not published in the code lists we checked. |
HALLOWEENEVENT | Reported new on October 16 | Free rewards; exact item counts were not published in the code lists we checked. |
Copy each code exactly as shown, including its capital letters. The current public lists agree on these four new strings; they do not provide an independently verified item-by-item reward breakdown. We have left the reward details general instead of guessing.
How to redeem Anime Mysterious codes
- Open the official Anime Mysterious experience on Roblox.
- Join the official Roblox community if the game asks you to.
- Reach Level 5. Current guides report this as the redemption requirement.
- In the spawn lobby, look for the code character and interact to open the redemption box.
- Paste one code at a time and select Redeem. Read the game’s message to confirm whether it was accepted.
Guides disagree on the code character’s name: some call the NPC Naruto, while others spell it Naruta. Follow the character and interaction prompt shown in the current lobby rather than relying on the spelling alone.
Why an Anime Mysterious code may not work
- It expired: seasonal and milestone codes can be disabled after an update. A fresh in-game “invalid” response takes priority over an older list.
- Your account has not reached Level 5: level up and try again after the requirement is met.
- The code was already redeemed: these codes are generally described as one-use per account.
- The game server is out of date: leave and rejoin a current server after a major update.
- There is a typo or extra space: paste the exact uppercase string and remove spaces before or after it.
Where new codes are announced
The Anime Mysterious Discord and the official Roblox community are the best places to check after updates and player milestones. Do not install a script, browser extension, or third-party tool to redeem a code; the claim process happens inside Roblox.
How we checked this list
We compared the new-code lists updated October 16 by Beebom and October 17 by Pro Game Guides. Both name the same four codes. Neither source provides an exact reward breakdown for this batch, and AniNextUp could not validate them inside a live Roblox session at the time of this check. We will update this page when the game or its official channels confirm a change.
