Mines is a simple Bitcoin game played on a 5×5 grid of 25 tiles. A handful of tiles hide mines; the rest are safe. You choose how many mines to hide, then flip tiles one at a time. Every safe tile you reveal raises your multiplier, and you can cash out for your current payout at any moment. Hit a mine and the round ends.

Yes. Mine positions are chosen with a cryptographically secure random generator the instant a round starts — before you touch a single tile — so your picks can never change where the mines are. Payouts follow a published multiplier formula with a flat, transparent 1% house edge, the same on every round.

After you reveal k safe tiles on a grid of N=25 tiles with m mines, the multiplier is (1 − 0.01) × the product of (N − i) ÷ (N − m − i) for i from 0 to k−1. Fewer tiles left and more mines on the board mean each safe tile is riskier, so the multiplier climbs faster.

You set your own bet for each round, anywhere from the minimum shown in the game up to the table maximum. Your bet is deducted when the round starts and your payout is credited the moment you cash out.

Deposits are made in Bitcoin (BTC); the live minimum is shown on the Wallet page at the time you create a deposit. Withdrawals have their own minimum, also displayed in the withdraw form, and are paid out on-chain to the address you provide.

When you request a withdrawal your balance is debited immediately and the payout is sent on-chain. On-chain confirmation time then depends on the Bitcoin network. You can cancel a pending withdrawal to have the amount refunded to your balance.

New accounts start with free starter credits so you can try the game right away, and an in-app faucet lets you top up a small share of your balance over time. You can sign up with email or a social login in seconds.

Yes. The free Mines demo runs entirely in your browser — no account, no download, no deposit — on the same 5×5 board with the same multiplier formula and 1% house edge as the real game. If you do create an account, you also get free starter credits and an in-app faucet, so you can keep playing real rounds without depositing Bitcoin.

It's the same classic Mines game you'll know from sites like Stake, Roobet, BC.Game and Gamdom — a 5×5 grid where you dodge hidden mines and cash out before you bust — played with Bitcoin and provably fair, with a flat, transparent 1% house edge. The multiplier and odds follow the same math, so a Mines calculator built for any of those sites works here too.
