Prepaid credit your idle GPU earns · 400+ games and gift cards
Robux money your graphics card earns while you sleep
Your PC sits idle for hours every single day. Put those hours to work: the app runs AI jobs on your graphics card and your balance climbs while you sleep. Roblox gift cards are not in the English catalog yet, so what the balance buys here is prepaid credit that covers the same ground — Steam gift cards at 5, 10 and 20 EUR — alongside 400+ games and cards on the shelf. The balance does not expire, so holding it costs you nothing.
- A 5 EUR card: about two days on an RTX 5090
- 400+ games and gift cards already on the shelf
- Out of your own pocket: nothing
Three steps. That is the whole thing.
No catch, no subscription on our side, no small print. You rent out your graphics card for AI compute and get paid for it — during the hours you were not using the machine anyway.
Switch it on, forget it
Install the app, hit EARN, get on with your day. Setup takes about a minute.
The card works, the balance grows
Not gaming? Your GPU runs AI jobs. Launch Roblox and it steps aside instantly. You get paid by the hour.
Spend it when you want
Pick a prepaid code or a game in the store. The balance keeps until you decide.
How many days does your card need?
A 5 EUR Steam card takes two days on an RTX 5090, three on a 4090 and about six on an older 3090. The 10 EUR card takes four days on a 5090 and five on a 4090; the 20 EUR card takes seven and nine. Pick your exact model in the calculator and see the real number.

What the balance buys today
The English catalog does not stock Roblox gift cards, so this page will not pretend otherwise. What it does stock is prepaid credit in the denominations a Robux package actually costs — Steam gift cards at 5, 10 and 20 EUR — next to 400+ games and gift cards.
The code arrives right after you order and goes straight into the checkout field. Your balance does not expire, so if a Roblox card is the one thing you are waiting for, banking the balance until the catalog carries it costs you nothing — the hours your PC works are the same either way.

Frequently asked questions
You build a balance with GamerHash AI: the app runs AI jobs on your graphics card during the hours the machine is idle, and you get paid by the hour. That balance then buys prepaid credit in the GamerHash store. The money is real and so is the purchase — the difference is that your PC earned it instead of you.
Your card is idle anyway. Let it earn.
Setup takes a minute. Leave the machine on and the balance climbs by itself — two days to the first card, and it keeps until you decide what to spend it on.
