The Mines Casino Game: What It Is & Where to Play

The Mines casino game is a Minesweeper-style crypto-casino original: a 5×5 grid hides mines you choose (1–24), each safe tile raises your multiplier, and you cash out before you bust. It carries a fixed 1% house edge (99% RTP), and every honest site pays the same 0.99 ÷ probability multipliers. Here is how it works and where to play it.

What is the Mines casino game?

Mines is the signature game of the crypto-casino generation. It borrows the look of the classic Windows Minesweeper — a grid of tiles, some hiding mines — but turns it into a cash-out gamble. You pick how many mines are buried among the 25 tiles, anywhere from 1 to 24. Every tile you flip that is not a mine reveals a gem and pushes your multiplier higher. Cash out whenever you like to bank stake × multiplier; flip a mine and the round ends with the stake lost.

Names for it vary — the Mines betting game, the Mines gambling game, “the gem and mine game” — but they all describe this one title: same 25-tile board, same rules, same math at every casino that runs it honestly.

The clever part is that you set your own risk. One mine is a slow, low-risk grind where almost every pick survives. Twenty-four mines is a single 4% shot paying 24.75×. Most players sit in between, and the popular three-mine setup pays just under 2× for five safe picks — roughly a coin flip.

How the Mines game works

• Board: 25 tiles in a 5×5 grid.
• Mines: you choose 1–24 before the round; more mines = higher risk and reward.
• Gems: each safe tile flips to a gem and raises the live multiplier.
• Cash out: any time after one safe pick, locking in stake × current multiplier.
• Bust: hit a mine and you lose the stake; the round is over.

Rounds take seconds and bets start at a cent or two, which is a big part of why Mines spread so fast across crypto casinos. Unlike slots, nothing about the payout is hidden — every multiplier follows one public formula.

The odds and the house edge

With M mines, the chance of clearing k tiles is C(25−M, k) ÷ C(25, k), and the casino pays 99% of the fair inverse of that number:

That missing 1% is the entire house edge — a 99% RTP that holds at every mine count. Some landmark payouts:

Where to play the Mines game

Is the Mines casino game fair?

At the provably-fair sites we rank, yes. Each mine layout is derived from a hashed server seed, your client seed and a nonce, committed before you pick a tile. Rotate your seed and you can unhash the server seed and recompute every past board to confirm nothing moved. Provably fair proves honesty — it does not predict mines, and any “predictor” claiming otherwise is a scam. Full walkthrough on our is Mines rigged? page.
