Mines at 1Win
Mines is one of the simplest games in the 1Win casino, but unlike most instant-win titles, it isn’t a black box. The board is a fixed size, and the number of mines is a setting you choose — which means the exact probability of surviving any click can be calculated precisely, not estimated from vibes. This guide works through those numbers directly: corrected survival odds, the fair-value math behind the multiplier curve, an honest look at why published RTP figures for “Mines” disagree across the industry, and a cash-out framework built on the actual numbers rather than a feeling.
What Is Mines
Mines is a grid game played on a 5×5 board — 25 cells in total. Hidden among them are mines, and landing on one ends the round immediately, forfeiting your stake. The goal isn’t to clear the whole board — it’s to open as many safe cells as you’re comfortable with, then cash out before your luck runs out.
Before each round, you choose the number of mines: 1, 3, 5, or 7. Every safe cell you open increases your current multiplier. The more mines on the board, and the deeper you go, the faster that multiplier climbs — and the higher the chance your next click ends the round.
Mines is available in demo mode without registration, so you can learn the pacing and watch how the multiplier scales before wagering anything real. When you’re ready to play with real funds, registration takes a couple of minutes and unlocks the full casino section, including the standard, Royal, and Turbo versions of Mines.

How a Round Works
- Open Mines from the casino lobby — it launches in demo mode automatically if you’re not logged in.
- Set your stake. Bet sizes scale from a small minimum up to $200 per round.
- Choose the number of mines — 1, 3, 5, or 7 — which sets how many of the 25 cells are dangerous.
- Click Play. The grid appears with all 25 cells face down.
- Click a cell. A star means safe and your multiplier increases; a mine ends the round and the stake is lost.
- Keep opening cells, or click Cash Out at any point to collect your current winnings.
There’s no timer. You can take as long as you want between clicks, and the same mechanics apply whether you’re playing on desktop, in a browser on mobile, or through the Android or iOS app.
The Real Odds Behind Each Mine Setting
Because the board is always 25 cells and the mine count is a number you pick, the probability of surviving any specific click is exact. The chance your first click is safe is simply (25 − mines) ÷ 25. The chance of surviving several clicks in a row is the product of each successive click’s odds, since the pool of remaining safe cells shrinks with every click you clear — risk compounds, it doesn’t stay flat.
With a 25-cell grid and, for example, 3 mines placed randomly, the chance the first pick is safe is 22/25 (88%). If that pick is safe, the chance the second pick is also safe drops to 21/24 (87.5%) — and by the time 15 cells are already cleared, only 10 remain, 3 of which are mines, dropping the odds for the next pick to 70%. The risk doesn’t rise in a straight line; it accelerates as the safe-cell pool shrinks relative to the fixed number of mines.
Recalculating this precisely (using the standard combinatorial formula for a shrinking 25-cell pool) gives the following corrected survival percentages:
| Mines | 1st click safe | Survive 3 clicks | Survive 5 clicks | Survive 10 clicks |
|---|---|---|---|---|
| 1 | 96.0% | 88.0% | 80.0% | 60.0% |
| 3 | 88.0% | 67.0% | 49.6% | 19.8% |
| 5 | 80.0% | 49.6% | 29.2% | 5.7% |
| 7 | 72.0% | 35.5% | 16.1% | 1.3% |
A few things stand out that a purely qualitative description would miss. At 1 mine, surviving 10 clicks — nearly half the board — is still better than a coin flip, at 60%. At 7 mines, that same depth is essentially a long shot at 1.3%. The gap between 1 and 3 mines is bigger than it looks on the settings menu: going from 1 to 3 mines roughly triples your chance of busting by click 5 (from 20% to just over 50%), even though the setting itself only tripled the mine count, not the danger in a linear way. That’s compounding at work — each mine removed from the safe pool affects every click after it, not just the one where it’s revealed.
A practical read of this table: if you’re aiming to open 8–10 cells in a session, 1 mine keeps that realistically achievable most of the time. The same target at 5 or 7 mines is a low-probability outcome you should expect to miss more often than not — by design, not bad luck.
On a $20 bet with 3 mines active, cashing out after 5 safe cells (payout roughly 1.35x based on standard Mines paytables) locks in $27 — a modest but certain gain. Pushing to 10 safe cells might offer 2.1x ($42), but the probability of reaching that point without hitting a mine falls under 50%, meaning the expected value of pushing further is not automatically higher just because the multiplier looks bigger.

The Fair Multiplier Curve: What the Payout Should Look Like
Survival odds only tell half the story. The other half is what each safe click is actually worth — and this is where most Mines guides stop short. Using the exact combinatorial relationship between the survival odds above and a 100%-return (zero house-edge) payout structure, here’s what a mathematically fair multiplier looks like at each depth:
| Safe clicks | Fair multiplier (1 mine) | Fair multiplier (3 mines) | Fair multiplier (5 mines) | Fair multiplier (7 mines) |
|---|---|---|---|---|
| 1 | 1.04× | 1.14× | 1.25× | 1.39× |
| 3 | 1.14× | 1.49× | 2.02× | 2.82× |
| 5 | 1.25× | 2.02× | 3.43× | 6.20× |
| 7 | 1.39× | 2.82× | 6.20× | 15.11× |
| 10 | 1.67× | 5.06× | 17.69× | 74.70× |
These are fair-value reference figures — the multiplier a game would need to pay at each depth for the return to be exactly 100%, derived directly from the survival probabilities above (fair multiplier = 1 ÷ probability of surviving that many clicks). They are not 1Win’s published payout table. Any real-money multiplier table applies a house edge on top of this fair curve, which is what actually determines how much you’re paid relative to the mathematically “fair” number.
What this table is useful for regardless: it shows you the shape of the curve. Multipliers grow slowly at first and accelerate sharply as the safe pool shrinks — at 7 mines, the jump from 7 to 10 safe clicks takes the fair multiplier from about 15× to nearly 75×, because each additional safe click at that depth is genuinely rare.
If 1Win’s actual paytable for a given depth looks wildly out of step with the shape of this curve, that’s worth noticing; if it tracks the shape closely but sits a few percentage points below it at every depth, that’s what a normal, modest house edge looks like.
RTP: Why the Numbers You’ll Find Online Don’t Agree
Search for Mines’ RTP and you’ll find genuinely conflicting figures — some sources cite numbers as high as 98–99%, others put similarly named games anywhere from 90% to 97% depending on mine count and operator. That spread isn’t a sign that someone’s lying; it’s a sign that “Mines” isn’t one game. Different casinos run their own in-house versions with their own payout tables built on top of the same basic mechanic, and a house edge quoted for one provider’s Mines doesn’t transfer to another’s — the same trap the CoinFlip and Tower guides warn about applies here too.
1Win has not published an official, verifiable RTP figure specific to its Mines game at the time of writing. The survival probabilities and fair-multiplier table above are exact — they come directly from the fixed 25-cell board and the mine count you choose, and no operator’s payout table changes those underlying odds. What isn’t knowable from the outside is how much of the fair payout at each depth 1Win’s actual multiplier table pays out — that’s the one number that determines the real house edge, and it isn’t published. Treat any specific RTP percentage attached to 1Win’s Mines with the same skepticism you’d apply to an unsourced RTP figure for Tower or CoinFlip: the survival odds and fair-multiplier shape above are certain; the real payout-to-fair-odds ratio is not.

When to Cash Out
The cash-out decision in Mines is the same fundamental question as in any game of this type, but the grid format makes it feel more deliberate — you’re physically choosing each step rather than watching a line move.
Set your target depth before the round starts, using the tables above rather than a feeling. At 5 mines, an 80% chance of surviving your first click can feel safe enough to justify pushing further — but the survival table shows that drops to under 30% by click 5. Deciding in advance to stop at click 4 or 5 on that setting is a materially different decision than deciding mid-round, once the rising multiplier is already making the next click feel safer than the math says it is.
Weigh what a loss costs at your current depth, not just what the next click adds. After 10 safe cells at 3 mines, you’re sitting on a run that only had roughly a 20% chance of happening in the first place. Losing it back costs more — in stake and in accumulated multiplier — than a loss at click 2 would have.
Size the stake to the depth you’re aiming for, not the other way around. On a $50 bankroll for a session, a $2–$5 stake per round at 1–3 mines allows dozens of rounds even through a losing streak, while the same bankroll at 7 mines with a $10 stake can be exhausted in a handful of unlucky rounds — the fair-multiplier table shows why: at 7 mines, most of the payout is concentrated in the rare deep runs, so a short losing streak is the expected pattern, not an anomaly.
The board has no memory. Mine positions are fixed at the start of the round and don’t shift based on what you’ve already opened. A long safe streak doesn’t mean the remaining cells are “due” to clear — the survival table above already accounts for the full compounding effect of a long streak; it isn’t evidence of anything beyond what the math already predicted.
Demo mode is useful specifically for this: because the mechanics are identical to real-money play, you can watch how the survival percentages above actually play out in practice and get a feel for where your own target depth should sit, before doing the same with real funds. It’s also worth checking a game’s terms before assuming any active bonus balance contributes fully to Mines — low-volatility instant games are commonly weighted differently than slots in wagering requirements.

How Mines Differs from Royal Mines and Turbo Mines
1Win offers two other mine-style games, and the difference isn’t just cosmetic.
Royal Mines uses a grid rather than the standard 5×5, which changes the safe-cell-to-mine ratio at every stage — verify the exact grid size in-game, since this directly changes the probability math above.
Turbo Mines keeps the same 25-cell logic as standard Mines but is built for faster, higher-tempo sessions — rounds resolve more quickly, suiting players who want to run many rounds in a short time. Standard Mines, by contrast, has no round-to-round time pressure at all, which suits a more deliberate, one-decision-at-a-time approach.
The practical choice: if you want full control over pacing and time to sit with each decision, standard Mines is the right pick. If you want speed, Turbo Mines fits better. Royal Mines sits closest to standard Mines conceptually but deserves its own look at the paytable rather than borrowing the numbers above.
Who This Game Is For
Mines suits players who want active involvement in each round — every click is a decision with a direct, calculable consequence, not a passive spin. If you’d rather set a bet and watch an outcome resolve on its own, Mines will feel more demanding than a slot.
1 or 3 mines suit newcomers or anyone who wants a session where reaching a meaningful depth (8–10 cells) is a realistic, majority-likely outcome rather than an exception — the survival table above shows exactly how often that holds at each setting.
5 or 7 mines suit players who’ve already internalized how fast survival odds fall off. At 7 mines, most rounds are built to end early, and a deep run is the exception that produces the outsized payout, not the norm to expect.
Mines is not a fit for anyone looking for a pattern that beats the math. No cell-selection order — corners first, diagonals, zigzag, or any other sequence — changes the probabilities in the tables above. Mine positions are randomized at the start of each round independently of where you click, and no selection pattern shifts that. Guides that claim otherwise, including ones citing specific “reduced bomb density” on edges or corners, or offering “predictors” and “signal bots,” are describing patterns and tools that the game’s randomization simply doesn’t support — treat those claims with the same skepticism as an unsourced RTP figure.
