Code Rules & Troubleshooting

If Register Coupon is missing from the in-game settings, clear Chapter 1 Episode 4 before checking again. iPhone and iPad players can use the official browser coupon registration page instead.

A rejected coupon may already be expired, previously redeemed on the account, or entered incorrectly. Chaos Zero Nightmare campaigns can use very different redemption windows, so check the individual expiry rather than assuming a coupon remains available for the full season or update.

New Code Announcements

Smilegate and the Chaos Zero Nightmare team distribute coupons through the official STOVE community, social channels, special programs, seasonal campaigns, livestreams, and major update celebrations. There is no fixed coupon schedule, and the August 19 Arabella update has not introduced a replacement public coupon after CZNS40729START expired.

When does Register Coupon unlock in Chaos Zero Nightmare?

The in-game Register Coupon option becomes available after clearing Chapter 1 Episode 4. If the option is missing on a new account, continue the main story and check Account Settings again afterward.

Can Chaos Zero Nightmare coupons be redeemed on iPhone and iPad?

Yes. iOS and iPadOS players can use the official Chaos Zero Nightmare coupon registration website with the account linked to their game data. This avoids relying on an in-app coupon field on Apple devices.

Where do Chaos Zero Nightmare coupon rewards arrive?

Successfully registered rewards are delivered through the in-game mailbox. Reward mail should be collected promptly because coupon reward mail has a limited claim period after registration.

Can the same Chaos Zero Nightmare coupon be redeemed twice?

No. Promotional coupons are normally limited to one successful redemption per account. A code that has already been claimed on the same account can be rejected even before its overall campaign deadline.

Do all Chaos Zero Nightmare coupons have the same expiry date?

No. Each campaign can have its own redemption window. For example, MAYTHE4THCZN lasted only through May 10, while several Half-Anniversary coupons remained available through June 30 and CZNS40729START ended on August 20.

Which account should I use on the Chaos Zero Nightmare coupon website?

Use the STOVE or linked account associated with the Chaos Zero Nightmare character that should receive the reward. Check the account information carefully before registering the coupon so the reward is sent to the intended game account.
