To redeem a Roblox gift card, follow these steps:

1. Open a web browser and go to roblox.com/redeem. Gift cards cannot be redeemed through the Roblox mobile app or game consoles; you must use a browser

2. Log in to your Roblox account or create a new one if you don't have an account yet

3. Find the PIN or code on your gift card. For physical cards, scratch off the back to reveal the code. For digital cards, the code will be in your email or receipt

4. Enter the code into the Code box on the redeem page and click Redeem

5. You will see a confirmation message once the credit is successfully added to your account

6. The credit can be used to purchase Robux or Roblox Premium Memberships. If you have enough credit, you can convert it to Robux directly on the redeem page or from the Membership or Robux purchase pages

7. Each gift card redemption also grants a free virtual item, which will appear in your inventory

If you encounter problems redeeming the card, you can contact Roblox Support with details like your username, purchase information, gift card PIN, and images of the card or error messages

. In summary, always redeem Roblox gift cards via the official website roblox.com/redeem using a browser, enter your code, and then use the credit to buy Robux, Premium, or convert credit to Robux as desired
