Rainbet Mines
This is an one of the classic risk-based games in our Originals collection, and Rainbet Mines brings this format to life with customizable grids and adjustable difficulty. You can choose from four grid sizes ranging from 25 to 64 tiles and set the number of hidden mines before each round. Every safe tile increases your multiplier, and you can cash out at any point. The maximum RTP reaches 96.00%, with autoplay, demo mode, and provably fair verification included.
How to Start Playing Rainbet Mines?
Getting into your first round of Rainbet Mines takes only a few steps: find the game in the lobby, set up the board and start opening tiles. Everything runs in the browser, with no download and no separate app, and the layout works just as well on a phone. The board sits on top and the controls below it, so the bet amount, grid size and mine count always stay within reach.
- Open Mines in the lobby.
Scroll to the Originals row in the casino section and tap the Mines tile.

- Set your bet and grid.
Enter the stake, pick a grid size of 25, 36, 49 or 64 tiles, then move the slider to choose how many mines are hidden.

- Open tiles one by one.
Tap any square to reveal a gem. Each gem raises the multiplier, and the round continues until you stop or hit a bomb.

- Cash out or see the board.
Press cash out to lock your winnings. If a bomb turns up, the full layout is revealed with every gem and mine marked.

Before the first round, make sure your Rainbet casino balance covers the minimum entry. A deposit of 14.50 CHF in crypto or 29.00 CHF by card is enough to get started. Once the funds arrive, open the casino lobby and look for Mines Rainbet in the Originals row, between Plinko and Dice.
How Rainbet Mines Works
The idea behind Rainbet Mines is simple: a grid of closed tiles hides gems and bombs, and your goal is to open as many gems as you dare before cashing out. The bombs are placed at random before your first click, and that layout stays locked for the whole round. Every tile you open is either a gem that raises the multiplier or a bomb that ends the round on the spot. The screenshots below show how a typical round unfolds, from a closed board to the final reveal.



Grid Sizes and Number of Mines
In Rainbet Mines, you are not tied to one fixed field: you decide both how big the board is and how many of its tiles hide bombs. Together, these two settings define how risky each click feels and how fast the multiplier grows. The controls sit above the board. First, pick one of four grid sizes, which sets how much room you have to work with. Then use the mine slider to split those tiles between gems and bombs:

- 25 tiles: the 5×5 default, up to 24 mines, fastest rounds
- 36 tiles: a 6×6 board with more space for longer gem runs
- 49 tiles: 7×7, where the same mine count feels noticeably safer
- 64 tiles: the largest grid, built for high mine counts and steep coefficients
- Mine slider: gem count on the left, bomb count on the right, adjusted before every round
When you set up a board, look at the ratio of bombs to tiles rather than at the grid size alone. Ten mines on 64 tiles leave far better odds per click than ten on 25, while the RTP stays at 96.00% in both cases. So there is no single “best” setting, only the one that matches your patience: long, calm rounds or short ones with bigger jumps.
Rainbet Mines Multipliers and RTP
Every gem you open adds to your potential win, so it helps to know how that win is calculated. In Rainbet Mines, payouts follow a fixed formula rather than a table someone typed in by hand. The coefficient depends on just two numbers: how many bombs are on the board and how many gems you have already turned over. These are the key figures behind every payout:

- Max RTP: 96.00%, stated in the game info panel
- House edge: built into the coefficient itself instead of a separate commission
- Starting coefficient: 1.03x on a one-bomb board, 24.00x when 24 bombs are in play
- Growth pattern: each gem shrinks the pool of unopened tiles, so the next coefficient jumps higher than the last
- Ceiling: 2,208.00x on a three-bomb board cleared down to the final gem
The easiest way to see this growth is to follow one setup from start to finish. The table below tracks a three-bomb round on the 5×5 grid: the first gems add only a little, but once the coefficient passes 10x, every new pick multiplies the win several times over. In the game itself, the cash-out value refreshes after each gem, so you always see what you would take home right now.
Keep in mind that these figures apply to one specific setup only. Raising the bomb count pushes the whole curve upward: eight bombs pay 2.20x after four gems where three bombs pay 1.66x, and a 24-bomb board settles everything with a single correct guess at 24.00x. To find the exact CHF amount waiting behind the cash-out button, multiply the current coefficient by your stake.
Manual and Auto Play
Rainbet Mines offers two ways to play, depending on how much of the process you want to control yourself. You switch between them with the Manual and Auto tabs above the bet field. In Manual mode, you tap every tile by hand and decide when to stop. In Auto mode, you set the pattern once, and the game plays the rounds for you until a stop condition is met. Here is what you can configure in Auto mode:

- Tile selection: mark the squares you want opened each round, in any arrangement across the grid
- Round count: set a fixed number of rounds or leave it running until you press stop
- On win: keep the stake flat or raise it by a chosen percentage after a successful round
- On loss: same two options, applied after a bomb ends the round
- Stop on profit: halt once net winnings reach a CHF figure you enter beforehand
- Stop on loss: the same limit in reverse, closing the session before losses run deeper
Players often ask whether Auto mode gives any edge, and the short answer is no. It is not a bot in the sense some forums use the word, and it knows nothing about where the bombs are. The feature simply automates the clicks, while the same algorithm decides the outcome whether you or the timer makes the pick. Most players use it to test a staking pattern across 50 or 100 rounds without sitting through every click.
Rainbet Mines Demo Play
If you want to get a feel for Mines before betting real money, a demo version is the easiest way to start. Free copies of the game are hosted on third-party sites and run on virtual credits, so nothing is connected to your balance: the session costs nothing and pays nothing. What a demo does give you is a chance to learn the controls and watch how coefficients move before any CHF leaves your wallet. A well-made demo usually offers the following:

- Bomb settings: the full 1 to 24 range, same as the paid board
- Coefficients: identical values at every gem count, so the math carries over directly
- Virtual credits: reset with a page refresh, no limit on how often you restart
- Auto mode: works the same way, useful for watching a pattern play out over many rounds
- What is missing: no seed verification, no bonus eligibility, no transaction history
Still, a demo is only a rehearsal, and it helps to know its limits. Any simulator you find in search results is not ours, and we have no control over how it works. These copies are not connected to our servers, their results cannot be verified, and some are tuned to pay out more often than the real game. Use them to see the layout and practise the controls, but not to judge your odds, because a copy tells you nothing about how the real board behaves.
Rainbet Mines Strategy and Risk
Since every Mines round is random, it is fair to ask what a strategy can really do. The honest answer is that no sequence of clicks beats a 4% house edge over enough rounds, and anyone selling a system that does is selling fiction. What a strategy does control is variance and session length – how often you win, how much each win returns and how fast a bad run drains your balance. These are real levers, and the approaches below show how to set them on purpose:

- Low-bomb grinding: one to three bombs, cash out at three or four gems, frequent small returns around 1.40x
- Fixed exit point: decide the coefficient before the round starts and take it every time, no mid-round changes
- High-bomb single pick: 15 to 24 bombs, one gem, cash out immediately for a payout between 2.40x and 24.00x
- Flat staking: the same CHF amount every round, which keeps a losing streak from scaling out of control
- Session caps: set stop-on-profit and stop-on-loss figures in auto mode and let them close the session for you
Each of these approaches trades one thing for another, and none of them changes the long-run return. The one tactic worth avoiding is chasing losses by doubling the stake after every bomb: it is the quickest way to hit a deposit limit, whatever the latest Reddit threads recommend. A safer routine is simple. Set a budget you are fine losing, pick a bomb count that suits it, and stop when either cap is reached.
Is Rainbet Mines Provably Fair?
Yes, and you run the proof yourself. Mines belongs to the Rainbet Originals, which are covered by the casino’s own Provably Fair system with a dedicated page linked in the site footer. There you can check rounds from your own session and confirm each result was fixed before your click. Every round is built from a hashed server seed, your client seed and a nonce, and together they decide where every bomb sits.
| Element | What it does |
| Server seed | Created by Rain Bet and shown as a hash while in use, revealed in full once you rotate it |
| Client seed | Your own value, which you can change on the Provably Fair page |
| Nonce | A counter rising by one with each bet, so every round calculates separately |
| Your Seeds section | The part of the Provably Fair page that shows the seed pair behind your current rounds |
| Seed rotation | Replaces the active pair and reveals the old server seed for all bets placed with it |
| Verification | Hash the revealed server seed to match it with the one shown before play, then enter both seeds and the nonce into a verifier to rebuild the bomb layout of any bet |
The same mechanism is why every Mines hack on Telegram falls apart. The server seed behind your current rounds stays hidden until you rotate it, so nobody can read bomb positions mid-round, and anyone charging 30 CHF for a predictor is selling a screen recording.
