The best way to top up Roblox is an official Roblox gift card redeemed on the Roblox website, not a purchase inside the app. The reason is simple: Roblox itself gives up to 25% more Robux when you buy on the website or with a gift card. On Refillarena you will find cards in US dollars, euros, Saudi riyals, UAE dirhams and more, delivered by email as soon as your payment is confirmed.
This guide shows how many Robux each card gets you, which card to pick, how to redeem the code step by step, and the truth about free Robux sites.

Why a gift card beats buying Robux in the app
The same money does not buy the same number of Robux everywhere. At current Roblox prices, USD 9.99 buys 1,000 Robux on the website or with a gift card, but only 800 Robux in the mobile app. That is 200 extra Robux for the same spend.
More Robux
Up to 25% more Robux than buying in the mobile app, as shown on Roblox's own Robux purchase page.
Works in any country
Roblox confirms that all its codes can be redeemed worldwide, and the value converts automatically to your account's currency.
No bank card needed
You do not need a card your app store accepts. Pay with crypto or the other payment options shown at checkout.
Easy to gift
Send the code to your child or a friend without sharing bank details or any password.
How many Robux do you get per card?
When you redeem a card, its value is added to your account as Roblox Credit in your account's currency, which you then turn into Robux. On the Roblox website that works out to roughly 100 Robux per US dollar. These are current Refillarena card prices with an approximate Robux estimate:
| Card | Refillarena price | Approx. Robux (via website) |
| USD 10 | USD 10.14 | about 1,000 |
| USD 25 | USD 25.35 | about 2,500 |
| USD 50 | USD 50.70 | about 5,000 |
| EUR 10 | USD 12.04 | about 1,100 |
| EUR 25 | USD 29.77 | about 2,800 |
| SAR 50 | USD 13.51 | about 1,300 |
| AED 50 | USD 14.22 | about 1,300 |
| AED 100 | USD 28.44 | about 2,700 |
The Robux figures are estimates. Roblox sells Robux in fixed packages whose prices depend on your account currency and can change, so treat them as a comparison guide and check the current packages on the Roblox Robux page after redeeming. Refillarena card prices change too, so check the product page before paying.
Which card should you pick?
Because codes work in every country, pick the card that suits your budget and currency. Saudi and UAE cards start at 20 riyals or dirhams, about USD 5.60, which is a cheap way to try the method first.

Free Robux and free Robux codes: are they real?
Searches for free Robux without human verification, free 400 Robux codes and modded Roblox with unlimited Robux are very common. The truth is that your Robux balance is stored on Roblox's servers, so no website, app or modded version can create Robux for your account. Sites that ask for your username and password, a "human verification" or app downloads are after your account, your data or ad revenue.
- Never enter your Roblox password anywhere except roblox.com.
- Do not install modded versions. They can steal your account and get it banned.
- The real free options are limited: official promo codes Roblox publishes and in-game events, which usually give items rather than Robux.
If you want guaranteed Robux, the smallest Saudi or UAE card starts at about USD 5.60 and gives more Robux than the app does for the same money.
Important terms before you buy
- Roblox gift cards cannot be refunded or exchanged for cash, and each card is redeemed in full once.
- If the account holder is under 18, Roblox requires a parent's or guardian's consent to redeem.
- You can redeem several cards on the same account, entering them one at a time.
