Navigate a 5×5 minefield, reveal hidden gems, and cash out before detonating a mine. The more mines you set, the higher your multiplier climbs with every safe tile you uncover.
Rainbet Mines is one of the most strategically deep Originals games available at the casino. The game takes place on a 5×5 grid of 25 face-down tiles. Before each round you set two parameters: your bet size and the number of mines to hide (anywhere from 1 to 24). The remaining tiles conceal gems. Your objective is to flip tiles one by one, collecting gems and watching your multiplier grow, then cash out before a mine ends the round.
The mechanic is deceptively simple but mathematically rich. With just 1 mine in play, the 25-tile grid is almost entirely safe — your multiplier grows slowly, but you can reveal nearly all tiles without much risk. Crank mines up to 20 and suddenly only 5 safe tiles remain on the board, yet each gem you find multiplies your bet dramatically.
Unlike slots, Mines places every decision in your hands. You choose when to be aggressive and when to bank your winnings. No spin button, no reels — just pure probabilistic decision-making on every click. Combine this with 20% rakeback from BOOST20 for maximum value.
💡 Core principle: The expected value of Mines stays near 99% RTP regardless of mine count. The mine count changes your risk profile — not your long-run expectation. Choose the count that matches your play style, not the one that promises the biggest wins.

| Mines Range | 1 – 24 |
| Gem Count | 25 minus mines |
| Max Multiplier | ~1,000x+ |
| RTP | 99% |
| Provably Fair | ✅ Yes |
| Rakeback (BOOST20) | 20% |
From placing your bet to cashing out — the complete flow of a Mines round.
Use the mine slider to select how many mines are hidden in the grid. Lower counts (1–5) give steady small multipliers. Higher counts (10–20) create explosive multiplier potential with each safe reveal.
Enter your wager. Mines works with any bet size — from micro-bets of $0.01 to large stakes. Your total payout equals your bet multiplied by your cash-out multiplier.
Click the green Start button. The 25 tiles flip face-down and the game begins. Your bet is locked in and the provably fair seed determines mine placement.
Click any tile to reveal it. A gem means you're safe and your multiplier increases. A mine ends the round and your bet is lost. Watch your current multiplier display after each safe reveal.
Press Cash Out at any moment after at least one gem is revealed. Your payout instantly transfers to your balance at the current multiplier. Waiting longer means higher rewards — but higher risk.
After each round, use the Provably Fair verification tool to confirm the mine placement was predetermined and unmodified. Paste the client and server seeds to audit any game.
Understanding the math behind each mine count setting helps you make smarter cash-out decisions.
| Mines | Safe Tiles | 1st Reveal Safe | 5 Reveals Safe | Approx. Multiplier (5 Gems) | Risk Level |
|---|---|---|---|---|---|
| 1 | 24 | 96.0% | 80.0% | ~1.25x | Very Low |
| 3 | 22 | 88.0% | 55.0% | ~2.0x | Low |
| 5 | 20 | 80.0% | 36.0% | ~3.5x | Medium |
| 10 | 15 | 60.0% | 10.0% | ~15x | High |
| 15 | 10 | 40.0% | 2.0% | ~80x | Very High |
| 20 | 5 | 20.0% | <0.1% | ~1000x+ | Extreme |
| 24 | 1 | 4.0% | N/A | ~1000x+ (1 tile only) | Maximum |

Three proven approaches to Rainbet Mines based on risk tolerance and session goals.
Settings: 1–3 mines · Cash out at 3–5 gems revealed
With 1–3 mines on a 25-tile grid, the vast majority of clicks will be safe. You build up small multipliers (1.1x to 3x) reliably and frequently. The conservative strategy is not about big paydays — it's about volume. Over 100 rounds, your hit rate stays high and rakeback from BOOST20 compounds meaningfully on your wagering volume.
Best used when: building session volume for rakeback, warming up, or playing with a reduced bankroll.
Expected session flow: Many wins of 1.2x–2.5x, occasional loss when you decide to push further. Net result stays close to 99% RTP over large samples.
Settings: 4–7 mines · Cash out at 5–8 gems revealed
The 5-mine configuration is widely considered the sweet spot in Mines. Each successful reveal pushes the multiplier meaningfully upward while keeping the probability of each safe click above 70% for the first several tiles. Targeting a cash-out around 3x–8x per round gives a balance that many regular Mines players favour.
Best used when: you want meaningful multiplier growth without the extreme variance of high-mine configurations.
Auto-bet tip: Enable Rainbet's auto-bet feature, set a fixed mine count of 5, auto cash-out after 5 reveals, and let the session run with no manual intervention needed.
Settings: 10–20 mines · Push deep into the grid
High mine counts transform Mines into a high-variance game where a single successful reveal yields 5x–20x, and pushing deep into the board can reach 50x–1000x. The statistical reality is that these sessions end in a mine the vast majority of the time — but when they don't, the payout can be session-defining.
Best used when: you have a session goal (e.g. 10x profit or bust) and are comfortable with high variance play.
Bankroll rule: Never risk more than 1–2% of your total balance per round in aggressive configurations. The variance is extreme and strings of consecutive mine hits are common.
Mines is a game of controlled risk, and your bankroll management strategy should reflect that. Unlike slots where spin size is the only lever, Mines gives you two levers: bet size and mine count. Both affect variance.
A conservative baseline: never bet more than 1% of your session bankroll per round. On a $100 session, that means $1 bets. This gives you 100 rounds of action and survives most downswings without exhausting your balance.
If your bankroll is healthy and you want to be aggressive, increase the mine count rather than the bet size. A $1 bet with 15 mines gives similar expected variance to a $3 bet with 3 mines, but caps your downside at $1. This preserves more rounds of action.
Set a hard stop-loss before you start — typically 30–50% of your session bankroll. If you hit that threshold, end the session. Chasing losses in Mines by increasing mine counts is one of the fastest ways to empty a bankroll.
With BOOST20 active, 20% of your net losses come back every 24 hours. On a $50 net-loss session, that's $10 back automatically. Factor this into your session math — your effective loss rate is reduced by approximately 20% compared to playing without rakeback.
Rainbet's Mines auto-bet mode allows you to define a complete session strategy and run it hands-free. Here's how to configure it effectively.
| Mine Count | 5 (balanced) |
| Auto Cash-Out After | 5 gem reveals |
| On Win | Reset to base bet |
| On Loss | Reset to base bet |
| Stop After Win | Optional: 3× profit goal |
| Stop on Balance | Set floor at 50% of session start |
Avoid Martingale (doubling after loss) with high mine counts — the variance makes loss streaks of 5–10 consecutive hits common, which would require 32–1024× your original bet to recover.
⚡ Auto-bet pro tip: Set a pre-defined number of rounds (e.g. 200) rather than running indefinitely. Reviewing results after a fixed sample gives you a clearer picture of your session performance.
Rainbet Mines uses a provably fair system — a cryptographic method that guarantees neither the casino nor the player can influence the outcome after a round begins. Here is the full verification flow:
Server Seed: Before the game, Rainbet generates a random server seed and gives you a hashed version of it. Because it's hashed, they can't change it without you noticing, but you can't calculate the mine positions from the hash alone.
Client Seed: You generate (or modify) a client seed. This is combined with the server seed to determine mine placement.
Nonce: Each bet increments a nonce counter, ensuring every round produces a unique result even with the same seeds.
After the Round: Rainbet reveals the original server seed. You can then independently calculate the mine placement using the published algorithm and confirm it matches the round you played.
This means Rainbet cannot secretly shift mines to wherever you click — the positions are locked in before the round begins, and any tampering would be detectable.
Copy your server seed hash before the round from the Provably Fair panel.
Note your client seed and nonce from the same panel.
After the round, click Verify — Rainbet reveals the full server seed.
Use an independent calculator to confirm mine positions match the revealed result.

Mines stands out as the highest-control Original — every aspect of your session from mine density to cash-out timing is fully in your hands. Players who enjoy making frequent, consequential decisions tend to favour Mines over games with more passive mechanics.
Start with 3–5 mines. This setting gives you reasonable multiplier growth while keeping each tile reveal at a relatively safe probability. As you get comfortable with the game's feel and payout structure, you can experiment with higher counts.
No. The mine count is locked in when you start a round. You can only change it between rounds. Once the round begins, the mine placement is fixed by the provably fair seed.
Yes. All Mines wagers contribute fully to your rakeback calculation. The 20% rakeback is applied to your net losses across all games including Mines, paid every 24 hours when you use code BOOST20.
Rainbet has a site-wide maximum payout cap. Check the current limits in the game settings or Rainbet's terms. For extremely high mine counts (20+), the theoretical multipliers can reach 1,000x or more — but hitting those requires revealing a very small number of safe tiles.
Your round remains active. If you have revealed gems and a pending cash-out multiplier, the game will be waiting when you return. Your bet is not automatically cashed out — you must return and either cash out manually or continue revealing tiles.
Yes. Rainbet's auto-bet feature for Mines lets you set the mine count, automatic cash-out after a specified number of gems, and win/loss conditions. It's ideal for running a consistent strategy over many rounds without manual intervention.
