Chaos Zero Nightmare Codes (July 2026)

Chaos Zero Nightmare is a deck-building gacha RPG set in a post-apocalyptic world overrun by the corrupting force known as Chaos. Redeem codes hand out crystals, summon materials, and upgrade items that speed up your progress without spending real money.

Redeem codes on Android and PC

Android and PC players redeem codes from inside the game itself, without visiting a separate website.

Launch Chaos Zero Nightmare and log into your account.

Tap the settings icon in the lower right corner of the main screen.

Select the silhouette icon on the side menu to open your account settings.

Tap Register Coupon. This option becomes available under Account Settings once you clear Chapter 1, Episode 4.

Type or paste your code into the text box, then confirm.

Open the in-game mailbox from the envelope icon and claim your reward.

A successful redemption shows a confirmation message on screen, and the reward appears in your mailbox within moments. Claim it from there before it expires, since unclaimed mail rewards are removed after 30 days.

Redeem codes on iOS

iOS does not support in-app coupon entry, so codes are redeemed through a browser instead.

Open the official Chaos Zero Nightmare coupon redemption page in a browser.

Enter the code into the input box and tap Register.

Return to the game, open the in-game mailbox, and claim your reward.

Where new codes get announced

Smilegate Holdings typically drops new codes around milestones such as anniversaries, content updates, or livestream events. The official Chaos Zero Nightmare Discord and the game’s social media accounts are the first places codes usually appear.

Redeeming codes early matters, since some are capped by a limited number of uses and others are tied to specific promotional windows. Keep the game updated to the latest version, as coupon entry can behave inconsistently on outdated builds.
