To add a Roblox card to your account, start by opening a web browser and going to the Roblox website. Next, log in using your account credentials. Once logged in, scroll down the page and find the “Gift Cards” option and click on it.
On the new page, look for the “Redeem Gift Cards” button in the upper right corner and click it. You will then be prompted to enter your gift card code. Carefully type in the code and follow the prompts to complete the redemption process.
After redeeming your card, you can use the Robux to buy items or upgrade to a Premium membership. This entire process can only be done through a web browser, not the Roblox app. Enjoy your new Robux and happy gaming!
