CookieRun: Kingdom Code Redemption Guide

To redeem a promotional coupon code in CookieRun: Kingdom, submit your unique User ID alongside the code on the official Devsisters coupon web page, then restart your game client to receive your items.

How to Redeem Coupon Codes

Follow this sequence to link your account credentials and claim promotional rewards:

1. Open CookieRun: Kingdom and access the game settings menu.
2. Select the Info tab to view and copy your unique User ID.
3. Navigate to the official Devsisters coupon redemption web page in your web browser.
4. Enter your User ID into the account field, ensuring the account name matches your profile.
5. Enter the promotional coupon code into the designated text field.
6. Submit the claim request to send the items to your account.
7. Fully close and restart the CookieRun: Kingdom app.
8. Open your in-game mailbox and claim your rewards before their expiration timer runs out.

Troubleshooting Redemption Errors

If rewards do not appear or the web portal returns an error, check these common failure points:

• Unrefreshed Game Client: Items sent from the redemption portal do not update in real time while the game app is running active. Completely close and reopen the app to force a mailbox update.
• Expired or Region-Locked Codes: A "coupon does not exist" or "expired" message indicates the code has passed its expiration date, reached its global usage limit, or is invalid for your region.
• Incorrect User ID or Guest Account: Promotional items are bound strictly to the User ID entered during redemption. Verify your ID if you play across multiple servers. If you are using a guest account, link it to a permanent login before redeeming, as claimed rewards cannot be transferred between separate profiles.
