Free Mines simulator: gems, multipliers and probability
This Mines demo gives you a 25-tile board and virtual credits to practise with. Each round hides between 1 and 24 mines. Reveal a gem to unlock cashout, keep playing to increase the potential return, or hit a mine and lose that round’s stake. The board is generated once at the start; it does not move a mine after you choose a tile.
How to use the Mines simulator
Choose a stake that your practice balance can cover and select the number of mines. Starting a round deducts the stake once and locks these settings until the round ends. Click or tap a hidden tile, or use the random-pick button. Random pick chooses from all unrevealed tiles, including mines; it does not improve your odds. Cash out after at least one gem, or reveal every safe tile to collect automatically.
How mine count changes your odds
With 3 mines there are 22 safe tiles. Your first pick has a 22/25, or 88%, chance of finding a gem. After one safe pick, 21 of the 24 remaining tiles are safe, so the next-pick chance is 87.5%. The probability of surviving both picks is 22/25 × 21/24 = 77%. The on-board percentage describes the next pick; the probability table describes the whole sequence up to that many gems.
More mines leave fewer safe tiles. With 24 mines, only one of the 25 tiles is safe: the first-pick chance is 4%. A successful pick clears the board and settles the round. Each new board is independent; previous results do not identify where the next board’s mines will be.
Understand the cashout multiplier
This simulator uses a custom total-return multiplier of 0.97 divided by the probability of reaching your safe-pick count. The multiplier includes the original stake. With 3 mines and 2 gems, that is 0.97/0.77, approximately 1.2597×. A 10-credit stake returns 12.59 credits after rounding down, leaving a net gain of 2.59 credits. Hitting a mine returns zero.
A larger displayed multiplier comes with a lower chance of reaching it. It does not mean the next tile is likely to be safe. The available-return amount shows what you can collect now; it is only added to your balance when you cash out or clear the board.
What the 97% model means
Before credit rounding, the probability of reaching a fixed cashout point multiplied by its return multiplier equals 97%. Actual returns are rounded down to 0.01 credit, which can lower the expected return slightly, especially for small stakes. This is a property of our practice model, not a quoted RTP for any provider’s Mines game. Short sessions can finish far above or below this average.
Review your practice results
The session summary includes completed rounds only, so an active round is not recorded as a loss while you are still playing. History records the stake, number of safe picks, outcome and amount returned for each completed round. The session net is total returned minus total staked. You can reset to 1,000 virtual credits between rounds; resetting clears the current history.
A simulator, not a Mines predictor
There is no winning tile pattern supplied by this tool. Its random board, mine count and payout calculation belong to this browser-based practice session. It does not connect to a casino, reproduce a provider’s official game or verify another game’s fairness. Virtual credits cannot be bought, withdrawn or exchanged for money. Use the displayed probabilities to understand risk rather than treating a past sequence as a signal for the next round.
This tool’s practice model, not a commercial RTP
Multipliers and survival probabilities on this page belong to the practice model already documented in the tool, including its target return. That figure is not a published RTP for a commercial Mines game. This simulator also cannot verify a provably fair operator round. For a fuller explanation of that limit, see the Aviator / Crash Simulator.
This is a free practice tool that uses virtual credits. It is not a way to make money, and it does not change the odds of any real-money game. If you gamble with real money, set a limit and use your local self-exclusion or support services if play stops being fun.
