TL;DR
- Robux and Roblox Premium can be paid with an international Libermall card on the Roblox website.
- In the mobile app, purchases go through the App Store or Google Play — you can link the Libermall card there too.
- Premium is a subscription: keep a buffer on the card for the monthly renewal.
Robux is Roblox's in-game currency, used for skins, accessories and game perks. Roblox Premium is a subscription that grants Robux every month and unlocks extra features. If your local card doesn't work, you can pay for both with a Libermall virtual card — an international Visa/Mastercard on a crypto balance.
Buying on the Roblox website
- Issue a card and top it up from your balance — USDT TRC-20 or TON.
- Sign in at roblox.com and open the Robux or Premium section.
- Choose a Robux package or a subscription plan, and card as the payment method.
- Enter the card details and a billing address in Latin letters.
- Confirm 3D Secure in the Libermall Card app if needed.
Buying in the mobile app
In the Roblox app on iPhone and Android, payment goes through the app store. You can add the Libermall card as a payment method to your Apple ID or Google account — see the guides for the App Store and Google Play. Purchased Robux land in the same Roblox account, whichever device you play on.
Tips
- For Premium, keep a buffer on the card — the renewal is charged automatically every month.
- If a child plays, issue a separate card for Roblox and top it up with a set amount — spending stays within limits.
- Buy Robux only in the official Roblox store or through app stores — “cheap Robux” on third-party sites is often a scam.
Roblox accepts international cards, but every payment is approved by the service itself. If a payment is declined, see why a payment gets declined.
FAQ
Where should I buy Robux — website or app?
Both work. On the website you enter the card directly in Roblox; in the app the purchase goes through the App Store or Google Play, where you can also link the Libermall card.
How do I cancel Roblox Premium?
Cancel it in the subscription settings wherever you subscribed: on the Roblox website or in the app store. The Libermall card doesn't affect this.
Can I give my child a separate card for Roblox?
Yes — issue a separate virtual card and top it up with the amount you want, so spending stays under control.
