How to play SatoshiMines
Mines is one of the simplest and most popular crypto casino games. On SatoshiMines you play it with Bitcoin on a 5×5 grid: reveal safe tiles to grow your multiplier, dodge the hidden mines, and cash out whenever you like. This guide explains exactly how rounds work, how payouts are calculated, and how to think about risk.
Playing a round
1. Create an account and deposit
Sign up with email or a social login, then send Bitcoin to your personal deposit address. Your balance updates once the deposit is detected.
2. Choose your bet and mines
Pick how much to wager and how many mines to hide on the 5×5 grid. More mines means higher risk and a faster-growing multiplier.
3. Reveal safe tiles
Flip tiles one at a time. Each safe tile lifts your multiplier and your potential payout. Avoid the hidden mines.
4. Cash out before you bust
Cash out at any point to lock in your current payout. If you reveal a mine first, the round ends and your bet is lost. Then withdraw your winnings on-chain whenever you like.
How multipliers and the house edge work
The grid has N = 25 tiles. You choose how many of them hide mines (m). After you reveal k safe tiles, your multiplier is:
multiplier = (1 − 0.01) × Π (N − i) ÷ (N − m − i), for i = 0 … k − 1The 1% house edge is the only edge built into the game, and it is the same on every round. For example, on a 25-tile grid with 3 mines, revealing your first safe tile gives a multiplier of about 0.99 × (25 ÷ 22) ≈ 1.13×. The fewer tiles remain and the more mines on the board, the faster the multiplier climbs — and the higher your chance of busting.
Is the game fair?
Yes. The positions of the mines are decided with a cryptographically secure random number generator at the instant the round begins — before you reveal a single tile. Nothing you do during the round can move a mine, and the house edge is a fixed, published 1%. Payouts are computed from the multiplier formula above, so the math is transparent and identical for every player.
A simple strategy
There is no way to beat the house edge over the long run, but you can shape your risk. Picking fewer mines gives slow, steady multiplier growth and a higher chance of reaching a modest cash-out. Picking more mines offers big multipliers quickly but busts more often. Decide your target multiplier before you start, cash out when you hit it, and only ever play with funds you can afford to lose. SatoshiMines also offers self-exclusion and other responsible-gaming controls if you want to take a break.
Frequently asked questions
What is the Mines game?
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.
Is SatoshiMines fair?
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.
How are the multipliers calculated?
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.
How much does it cost to play?
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.
What is the minimum deposit and withdrawal?
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.
How fast are withdrawals?
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.
Do I get anything for signing up?
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.
Can I set limits or take a break?
Yes. SatoshiMines includes responsible-gaming controls, including self-exclusion, so you can take a break from play whenever you choose. Please only play with funds you can afford to lose.
