MineroBux is a free platform where you earn Robux gift cards by watching short video ads and playing a mines-style game. No purchases, no subscriptions — just watch, play, and cash out.

Is MineroBux really free?

Yes, 100% free. You never need to enter payment information or buy anything to earn. Advertisers pay to show you ads, and we share a portion of that revenue with you as credits.

How do I get free Robux on MineroBux?

Create a free account to get 1,000 bonus credits, watch ads (up to 100 per day) to earn more credits, play the Mines game to multiply credits into a USD balance, then redeem your balance for a real Roblox gift card — 500 Robux for $4.99 or 1,000 Robux for $9.99.

What can I redeem my balance for?

500 Robux for $4.99 USD balance, or 1,000 Robux for $9.99 USD balance. Codes are genuine Roblox gift cards delivered to your email within 24–72 hours of approval.

How does the Mines game work?

You wager ad credits on a 4×4 grid. Choose how many mines are hidden (1–15), then click cells to reveal them — each safe reveal increases your multiplier. Hit a mine and you lose your wager. Cash out any time to lock in your winnings.

How many ads can I watch per day?

You can watch up to 100 ads per day. The limit resets at midnight UTC.

How MineroBux Gives You Robux at $0 Cost

MineroBux accumulates a USD balance from ad revenue — not from your wallet. You earn credits by watching ads, convert them to USD balance via the Mines game, and redeem for Roblox gift cards at our cost. Your out-of-pocket spend: $0. Time investment: 30–60 min/day for 5–14 days.

The Robux 'Spread' Explained

Roblox takes a significant cut at every point: 30% marketplace fee on creator sales, and a 72.3% haircut on DevEx (selling 100 R$ for $1.25, getting back $0.35). This spread funds Roblox's operations. It also means buying Robux directly is the most expensive option — which is why earning free Robux via MineroBux has such high practical value.
