In the Mines game you pick how many mines hide in a 5×5 grid, then flip tiles one at a time, and each safe tile raises your multiplier until you cash out or hit a mine. Mines pays back between 95% and 99%, depending on the studio. More mines means more risk, not a better return.

The 30-second version
Mines is an instant game rather than a crash game, though it sits in the same family. The return depends entirely on the studio: Spribe runs 97% RTP, Turbo Games 95%, and the crypto-casino originals from Stake and BC.Game run 99%. Picking more mines steepens the multipliers but does not change the RTP, it only raises the volatility. How the crash family works.

⚡ How a Mines round works
A Mines round works like this: you set your bet and the number of mines, then reveal tiles on the 25-tile grid one at a time. Each safe tile raises your multiplier, and you can cash out after any safe tile. Hit a mine and the round ends and you lose your bet. The steps are the same on Spribe Mines (97% RTP) and Turbo Games Mines (95% RTP). Only the numbers behind them differ. Stake’s Moles game uses the same idea: each hit raises your multiplier, and one miss ends the round.
Set your bet and choose the mine count
This is the single volatility dial. More mines means fewer safe tiles, steeper multiplier growth and lower survival odds. Spire+ by Pragmatic Play works the same way with skulls: more skulls in a row means lower odds of clearing each level.
The bombs are placed before your first click
Positions are determined cryptographically and committed via a hashed server seed. They are not moved during the round, which is the core provably fair property.
Reveal tiles one at a time
Each safe reveal (a gem, star or diamond depending on the studio) increases your multiplier. Hit a bomb and the round ends with the stake forfeited.
Bank or continue after each safe tile
You may cash out and lock the current multiplier, or push on for a higher one. Both studios offer autoplay and auto-pick; Spribe adds an Auto Game mode with stop conditions, Turbo Games adds a Turbo mode that repeats a reveal pattern.
The multiplier scales with risk and depth
With one mine the multiplier climbs slowly across many safe tiles. With ten or more it accelerates sharply, but survival collapses just as fast.

How it works
Every box you open safely raises the multiplier. The multiplier is the true odds of getting that far, times 97%. So over many rounds the game keeps about 3% of what is bet, whatever you do. Where the alarms sit is fixed before your first pick, using your device's own random number generator.

🎯 Mines odds: your chance of clearing 1, 3, 5 or 10 tiles
Your chance in Mines depends only on how many mines you set and how many tiles you open. On the 25-tile grid used by Spribe, Stake and BC.Game, one mine gives you an 80% chance of clearing 5 tiles, three mines give 49.6% and five mines give 29.2%. The chance that your very first tile is a mine is the mine count divided by 25, so 3 mines means a 12% chance of losing on the first click.
Each cell is the chance of opening that many safe tiles in a row. The maths is simple counting: with 3 mines, the first pick is safe 22 times in 25 (88%), the second 21 times in 24, and so on.
The second table shows what those odds pay. The first figure is a 99% game (Stake and BC.Game), the second a 97% game (Spribe). They are worked out from the RTP, so the game screen may round a little differently.
💡 Key insight
Different settings can give you the same bet. Three mines and 5 tiles has a 49.6% chance, and so does five mines and 3 tiles. On a 99% Mines both pay 2.00x. So pick the chance you want first, then choose any mix of mines and tiles that gives it. Try your own numbers in our Mines calculator.
Work out your own odds: pick a mine count below to see your chance of each safe tile and the multiplier you would reach.
| Tiles revealed | Chance this tile is safe | Cumulative survival odds | Multiplier | Verdict |

Multipliers shown use a 3% house edge (matching Spribe Mines). Actual multipliers vary by game and operator. The house edge means the expected value of every reveal is negative regardless of mine count.
🎮 Where Mines sits in the crash family
Mines is not a crash game, but it belongs to the same instant-game family and rewards the same discipline: knowing when to stop. The three formats differ in one thing above all else, the amount of decision-making you get inside a single round.

🔍 From Minesweeper to the casino game
Mines borrows its grid from a 1980s computer game but strips out the logic. Classic Minesweeper is a deduction puzzle with numbered clues; casino Mines replaces those clues with pure RNG risk, so there is nothing to deduce, only odds to weigh.
Mined-Out, by Ian Andrew
A ZX Spectrum title and the earliest clear ancestor of the grid-and-bombs idea.
Minesweeper goes mainstream
Robert Donner and Curt Johnson’s deduction puzzle reaches a global audience through Windows 3.x, cementing the visual language of tiles and hidden mines.
The format becomes gambling
Crypto casinos adopt provably fair Mines, swapping the clue layer for cryptographically committed random bomb positions. This is the moment a puzzle becomes a wager.
Spribe and Turbo Games ship Mines
Turbo Games launches its Mines in May 2021, Spribe follows in September. These become the two most widely distributed studio versions.
Hacksaw and the in-house originals follow
Hacksaw Gaming adds a configurable-grid Mines, and in-house versions from Stake and BC.Game cement it as a crash-adjacent staple.
🏢 The studios behind Mines
Spribe and Turbo Games make the two most widely played studio versions of Mines. Spribe Mines pays 97% RTP and Spribe holds a Malta Gaming Authority licence (MGA/B2B/562/2018). Turbo Games Mines pays 95% RTP and carries a Curacao licence only. That makes Spribe the higher-return, more regulated choice of the two.
Spribe
Founded in August 2018 with offices in Kyiv and Tallinn, Spribe is best known for Aviator (2019) and shipped Mines in 2021. It holds an MGA licence (MGA/B2B/562/2018) along with regulatory approvals in Gibraltar, Sweden and Ontario, and its games are tested by GLI, BMM Testlabs and iTech Labs. Spribe Mines runs a fixed 97% RTP across every mine count, on a 5×5 grid, with an operator payout cap typically set at 10,000x.
📝 For the record: Spribe’s UK software licence, held since December 2020, was suspended on 30 October 2025 on suitability grounds tied to the hosting requirements of the licensing framework, which Spribe characterised as an administrative issue. The suspension was lifted on 30 March 2026. Industry reporting noted that flagship Aviator was still not live with UK-licensed operators shortly afterward, so treat UK availability as in flux.
Turbo Games
Founded in 2020 and headquartered in Tallinn (with offices in Kyiv and Cyprus), Turbo Games is part of the Turbo Stars group and debuted with Crash X in March 2021. Its Mines title carries a Curacao licence only, with testing by iTech Labs and BMM Testlabs, and no MGA or UKGC approval. In practice that makes it a crypto and offshore product. Its RTP is 95%, a touch below the roughly 96% crash-game norm.
🔍 Worth noting
Turbo Games Mines is constantly confused with Galaxsys Turbo Mines. They are different games from different studios. Galaxsys Turbo Mines (released November 2023, MGA-licensed) reports an RTP band of 93% to 98.89% and a headline maximum in the tens of millions; Turbo Games Mines is the 95% Curacao title described here. If a source lists a multi-million max multiplier under the name Turbo Games, it has almost certainly mixed the two up.
📊 RTP and house edge
There is no single RTP for Mines, because the figure is set by the studio, not the format. Spribe returns 97% (a 3% house edge), Turbo Games 95% (around 5%), and the in-house crypto originals from Stake and BC.Game run 99% (1%). On every one of them, the return is the same whether you set one mine or twenty.
💡 Key insight
The number of mines is a volatility dial, not a value dial. Every mine setting returns the same RTP over time. A high mine count just trades frequent small wins for rare large ones, and the expected loss per pound staked never moves.
🔢 The maths behind the multipliers
Every Mines multiplier comes from one piece of combinatorics: the chance of surviving a given number of safe reveals. On a 25-tile grid with N mines, your odds of surviving the first pick are the number of safe tiles divided by 25, and each safe reveal drops both totals by one.
The fair multiplier after revealing a run of safe tiles is simply the inverse of that survival probability. The studio then multiplies it by its RTP factor: 0.97 on Spribe, 0.95 on Turbo Games, 0.99 on Stake and BC.Game. That is the whole engine.
Here is a worked three-mine round on Spribe, so you can see the survival odds fall and the multiplier climb in lockstep.
At each step the expected value is the survival chance multiplied by the posted multiplier, and that product always lands back at roughly 0.97. In other words you lose about 3% per bet on Spribe no matter how far you push, and a Stake player at 0.99 would see the same multipliers nudged up to a 1% edge (that five-tile cash-out becomes almost exactly 2.00x).
“You lose about 3% per bet on Spribe no matter how far you push.”
The headline multipliers come from full clears, where you reveal every safe tile. With one mine that is a 25x maximum; with three mines, 2,300x; with five mines, 53,130x. The theoretical ceiling across all settings runs into the millions, but it is academic: Spribe caps payouts at 10,000x, so the largest multipliers can never actually pay out. Those full-clear figures are the fair multipliers, before the studio’s RTP factor is applied; after Spribe’s 3% edge they come out around 3% lower, so a three-mine clear pays roughly 2,231x and a five-mine clear 51,536x, which is what the calculator below reports. This is the same expected-value logic that governs every crash game, and we prove the general result, variance and why no staking system beats it, in the crash gambling maths guide.
The bottom line: on Spribe Mines you give back 3% of everything you stake over time. Picking more mines changes how often and how violently you find out about that edge, not the size of it.
⚙️ The main Mines variants compared
The main Mines versions pay between 95% and 99% RTP: Turbo Games Mines 95%, Spribe Mines 97%, and the in-house Stake and BC.Game versions 99%. The highest returns sit on the least regulated platforms, and the lower returns on the more regulated ones. The table shows how the most common versions line up.
A few figures in that table are reported inconsistently across sources and are marked with an asterisk. Spribe’s selectable mine range is cited as both 1 to 24 (the mathematically complete range for a 25-tile grid) and 1 to 20, likely a build or operator difference. Turbo Games’ cap appears as a €1,000 cash ceiling alongside a far higher theoretical multiplier, and Hacksaw’s RTP is quoted at 94%, 96% and 98% on different operator pages because it is an operator-selectable figure. Where a version is crypto-only, expect the broadest selection and the highest advertised returns, with the least oversight. For the full picture of what is available, see our crash games directory.

🛡️ Is Mines provably fair?
Both Spribe and Turbo Games run their Mines games as provably fair, which means the bomb layout is locked and verifiable before you touch a tile. The generic mechanism, server seed plus client seed plus nonce, is the same one used across the crash family, and we explain it in full in the provably fair guide. What follows is what is specific to Mines.
Note the committed hash before the round
The studio publishes a hash of the next round’s server seed in advance. That hash is the commitment: the layout is already fixed.
Set or note your client seed
You can change the client seed, which proves the operator could not have tailored the layout to you.
Play the round
The mines do not move while you reveal tiles. Where you click changes nothing about where the bombs already are.
Reveal the server seed afterwards
Once the round ends the server seed is shown. Hash it yourself and confirm it matches the commitment you noted in step one.
Recompute the grid
Combine the seed pair and nonce to regenerate the layout and confirm the mines sat exactly where the round said they did.
🔍 Worth noting
The exact hash function for Mines is under-documented by the studios. Spribe’s Aviator is confirmed to use SHA-512, but its Mines grid generation is widely reported, secondhand, as SHA-256. Turbo Games does not publicly name the algorithm for Mines at all, so the common HMAC-SHA256 claim is an industry-standard inference, not a vendor statement. The verification workflow is sound either way; the specific algorithm label is the part to take with a pinch of salt.
🏆 How Mines compares to crash and Plinko
Mines gives you more choices per round than crash or Plinko. You decide to bank or carry on after every safe tile, while crash gives you one cash-out and Plinko gives you none once the ball drops. More choices do not change the return: Spribe Mines pays a fixed 97% RTP whatever you decide.
That extra agency is the appeal, and it is also the catch. A round with repeated decisions and a fast re-bet loop keeps you clicking, and the spatial map of safe and dangerous tiles makes each call feel skilful even though the odds are pure chance. The constant decision points do not change the maths, but they do change how engaged you stay.
The same features that make fast, high-frequency games like Mines so engaging have drawn rising scrutiny over player harm. We cover the research evidence, the risk factors and what regulators are doing in a dedicated guide: crash gambling and player harm.
💡 Common mistakes
The most common Mines mistake is thinking the mine count changes your return. It does not: Spribe Mines pays 97% RTP with 1 mine or with 20. The other big mistake is mixing up versions that look the same but are not.
- Believing more mines means worse value. The RTP is identical at every mine count. Only the volatility changes, so more mines simply makes the swings bigger.
- Thinking your cash-out point changes the return. Banking early or pushing deep changes variance, not expected value. The edge is constant across both.
- Confusing Turbo Games Mines with Galaxsys Turbo Mines. Different studios, different games, very different numbers. The names are close enough to trip up most review sites.
- Assuming every Mines game is regulated. The highest-RTP versions (Stake, BC.Game at 99%) are crypto-casino only. The regulated options run lower returns.
- Treating the headline max as reachable. The million-times multipliers are mathematically real but sit far above the operator cap, so they can never pay out.
❓ Frequently asked questions
Is Mines a crash game?
No. Mines is a grid-based instant game, not a crash game. There is no rising multiplier that crashes at a random point; instead you reveal tiles one at a time and decide after each one whether to bank. It sits in the same instant-game family as crash and Plinko, but its structure is different.
What is the RTP of Mines?
It depends on the studio. Spribe runs a fixed 97% (a 3% house edge), Turbo Games 95%, and the in-house versions from Stake and BC.Game run 99%. There is no single RTP for the format, because each studio sets its own.
Does choosing more mines improve your returns?
No. The RTP is the same whether you set one mine or twenty. A higher mine count makes the multipliers grow faster but makes survival much less likely, so it raises volatility without touching the expected value. The cash-out point you choose also changes variance, not the long-run return.
Is Mines provably fair?
On Spribe and Turbo Games, yes. The bomb positions are fixed and committed via a hashed server seed before your first click, and they do not move during the round. After the round you can reveal the seed, confirm it matches the pre-round hash, and recompute the layout to verify it. The exact hash function is not always disclosed by the studios.
Is Spribe Mines available in the UK?
It is in flux as of mid-2026. Spribe’s UK software licence was suspended in October 2025 over a hosting-requirement issue and reinstated on 30 March 2026. Industry reporting noted that Spribe’s flagship Aviator was still not live with UK-licensed operators shortly after reinstatement, so UK availability of Spribe titles should be checked operator by operator.
What is the maximum win on Mines?
The full-clear multipliers are large (25x at one mine, 2,300x at three, 53,130x at five) and the theoretical ceiling across all settings runs into the millions. In practice the operator cap binds first: Spribe caps payouts at 10,000x, so the very highest multipliers can never actually be paid.
Spribe or Turbo Games Mines, which is better?
For most players in regulated markets, Spribe is the stronger pick: a higher 97% RTP and MGA plus UK regulatory coverage. Turbo Games runs a lower 95% return on a Curacao licence, making it effectively a crypto and offshore product. The crypto-only versions from Stake and BC.Game offer the best 99% return but no mainstream regulation.
What are the odds of hitting a mine on the first click?
The chance your first tile is a mine is the number of mines divided by 25. That is 4% with 1 mine, 12% with 3, 20% with 5, 40% with 10 and 96% with 24.
How many mines should I pick?
There is no best number for value, because the RTP is the same at every mine count. Pick by the chance you want. With 3 mines you clear 5 tiles 49.6% of the time for about 2x. With 1 mine you clear 5 tiles 80% of the time for about 1.2x. With 10 mines you clear 3 tiles 19.8% of the time for about 5x.
