Mines game facts
Before any talk about risk, it helps to have the numbers in front of you. Everything in this table comes from the game’s info sheet, and that sheet, opened from Mines’ own menu, is what counts if you are unsure about a specific limit.
How do you play Mines?
Choose your stake and the number of mines, open tiles one by one and tap Cash Out before you hit a mine. If you hit one, you lose that round’s stake and the grid resets. Every safe tile shows a star and pushes the running multiplier up, and your win is your stake multiplied by the value at the moment you cash out. This guide covers how to play Mines, what RTP to expect and what changes with the number of mines, step by step from the official game sheet.
Open the game
Go to the Fast Games tab and choose Mines. The 25-tile grid appears closed, waiting for your bet.
Set your stake
Enter the amount for the round in the panel. While you get used to the game, stay at the minimum shown there.
Choose the mines
Select how many mines are hidden, from 1 to 20. This decision sets the risk for the whole round.
Open tiles
Every star raises the multiplier. You can tap tiles yourself or let the random tile button choose.
Cash out in time
The Cash Out button ends the round at the running total. Decide your target before you start, not halfway through the grid.
How many mines should I choose?
It depends on one thing only: how fast you want the multiplier to climb, and how many tiles you are willing to open before the round blows up. This is the only decision in Mines that is truly yours, and it is a straight trade-off with no free lunch.
The two extremes show the mechanism clearly. With 1 mine hidden, 24 of the 25 tiles are safe, and the first tile pays about 1.01x: almost nothing. To make the value grow you need to open tile after tile, in a long, slow round. With 20 mines, only 5 safe tiles remain, and the first one already pays about 4.85x, nearly five times your stake in a single tap. The obvious catch is that most rounds end right there.
There is no point memorising in-between values from other sites. The game panel shows the next tile’s multiplier in real time, before you tap. Get used to looking at that number: with every tap, it tells you what you are really risking.
What is the RTP of Mines?
It is 97%. Anyone searching mines RTP always finds the same number, because the game sheet states a single value for the game, not one per number of mines. What your choice of mines changes is the risk profile: the same house edge spread over rare, big rounds or frequent, small ones.
It is worth understanding what that 97% really means. It is a theoretical average calculated over a huge number of rounds by everyone, not a forecast of what you will take home. Put simply, for every 100,000 RWF that passes through the game across all players, about 3,000 RWF stays with the house. Over a session of twenty rounds, that number predicts nothing at all.
A high RTP is still a margin in the house’s favour. The expected value of every round is negative, whether you open one tile or ten, and no mine setting turns that around.
Is there a pattern in where the mines are?
No. The mines are placed by a random number generator at the start of each round. They stay where they are until that round ends and are placed again from scratch in the next one. There are no safer corners, no diagonals that «usually come up» and no tiles that become «cursed» after a mine.
There is a second, subtler mistake worth clearing up: the game does not store luck. Opening three stars in a row leaves nothing «owed» to you, and hitting a mine on the first tile five rounds running does not force the sixth to go well. The grid has no memory between rounds. Within a round, the multiplier simply reflects how much risk you have already taken, not a reward for earlier tiles.
Is auto mode worth using?
For most people, no, and it is fair to say why: auto mode is the quickest way to empty a whole balance without noticing. It lets you set up to 500 rounds in a row with the same stake, the same number of mines and the same number of tiles to open, and then it runs on its own while you watch.
The problem is not technical but about perception. When you tap yourself, every round costs a gesture, and there is always a split second to change your mind. On auto, 200 rounds pass in a few minutes and your balance drops silently, with no moment when your brain registers «I just bet again». The total only shows at the end, when there is nothing left to decide.
If you still want to use it, set your brakes before you start: a short number of rounds, the minimum stake per round and a loss limit in the settings. The random tile button is different. It only chooses a tile for you when you do not feel like deciding, and it changes neither the odds nor the multiplier.
Managing your money: what replaces «strategy»
There is plenty of content out there labelled mines strategy, and almost all of it promises what it cannot deliver. No sequence of taps, magic number of mines or pattern of tiles turns a negative expected value into a positive one. What does exist, and really matters, is controlling your exposure: deciding how much you risk, for how long and when you stop.
In practice there are four decisions, all made before the first round. First, the total for the session: money you could lose completely without any effect on your life, never money for rent, school fees or repaying a mobile money loan. Second, how much goes into each round: one-fiftieth of your budget is a sensible starting point, because it leaves room for a long run of lost rounds. Third, your exit target: how many tiles you will open before cashing out, decided in advance and not in the heat of the grid. Fourth, a loss limit and a win limit that end the session with no argument.
Notice one more detail of the format: Mines has no fixed round length, so there is no natural pause forcing you to breathe. That is a big difference from live dealer tables, where the dealer sets the pace and there are breaks between hands. If you feel you have lost track of time, the limit and self-exclusion tools in your account are there for that.
Is there a free Mines demo?
Much of the casino catalogue has a demo mode with play money, and when the free Mines demo is available, the button appears on the game’s own page. It is the right way to see the effect of each number of mines at no cost: play ten rounds with 2 mines, ten more with 15, and see the difference in pace for yourself. If the demo button is not visible, the game runs only with real money.
Playing Mines on your phone
Mines opens in your phone’s browser with nothing to install, and the 5×5 grid fits a portrait screen well. It is one of the quick-round games best suited to portrait mode, because it does not depend on real-time reactions: nobody takes the tile out of your hand because of half a second of delay on your mobile data.

If you want to compare formats before choosing, try Plinko from BGaming, where you decide nothing after dropping the ball, or the chicken game, which swaps the grid for a road you cross step by step. Like all casino games, Mines never counts towards sports bonus wagering.

Frequently asked questions
No. The setting is locked the moment the round starts, because that is when the mines are placed on the grid. To change the number, finish the current round and start a new one.
All the ones that are not mines: up to 24 tiles with 1 mine, and only 5 with 20 mines. Once every safe tile is open, the round ends automatically at that setting’s top multiplier.
Not at all. It only picks a closed tile for you, saving you the decision. The chance of that tile hiding a mine is exactly the same as if you had picked it yourself.
The game’s multiplier goes up to 10,000x, which only appears with extreme-risk settings and an almost fully opened grid. The cap in money depends on your stake and the limits shown in the game sheet.
No. The Sport Welcome Bonus is wagered 5x on accumulators of three or more selections priced from 1.5 to 10, which leaves casino games out. Always check the terms of the current promotion before betting bonus funds.
Yes. Spribe supplies a single version of the game, with the grid fixed at 5×5 and the mine range fixed between 1 and 20. What varies are the account’s bet limits, the currency and the promotions around it.
As long as you like: unlike timed games, there is no clock running, and you can think between taps. That freedom is deceptive, because a session can chain dozens of rounds in a few minutes without feeling like much time.
Neither is better in terms of theoretical return; only the way the risk is spread changes. Few mines give long rounds and small wins; many mines give big jumps and rounds that almost always end quickly.
