To claim coupon rewards in Cookie Run: Kingdom, you must submit your registered DevPlay account email and voucher code through the external DevPlay redemption web portal. The game client does not process coupon entries directly on most operating systems. Once submitted successfully, rewards arrive in your in-game mailbox.

Each promotional voucher can be claimed only once per DevPlay account. Enter the codes exactly as formatted below:

If you manage accounts on multiple servers (such as Pure Vanilla, Hollyberry, or Dark Cacao) under different DevPlay emails, you must submit the codes separately for each registered account.

Step-by-Step DevPlay Redemption Instructions

Follow these steps to locate your account identifier and redeem your rewards:

  1. Launch Cookie Run: Kingdom and open your kingdom view.
  2. Tap the menu icon in the upper-right corner of the screen and open Settings.
  3. Select the Info tab.
  4. Check the User Info section to find your linked DevPlay Account email address. Do not use your visible Kingdom Name.

  6. Type your complete DevPlay email address into the DevPlay Account field.
  7. Enter MISSEARTHBREAD26 into the Coupon Code field without leading or trailing spaces.

Troubleshooting Redemption Errors

If the DevPlay portal rejects an entry or items fail to arrive, check the following common issues:

  • Account Not Found: The portal requires the email address bound to your DevPlay account. Entering your in-game Kingdom Name or player handle will trigger an error. Guest accounts cannot receive portal rewards until they are linked to a supported login provider.
  • Invalid Code String: Copying and pasting codes on mobile devices often introduces an extra trailing space. Ensure there are no spaces before or after the code before submitting.
  • Already Used Code: Attempting to claim the same code twice on a single DevPlay account will return an error indicating the voucher has already been processed.
  • Mail Delivery Delay: During periods of high traffic after a new code release, mailbox dispatch can experience a slight queue. Wait a few minutes and restart the game app before attempting to submit the code again.
