Stake Mines Calculator: Multiplier Chart, Probability and Cash-Out Maths

Mines Calculator: Multiplier Chart and Probability

This Stake Mines calculator takes the mine count and the house edge and returns the full payout table. The chance column is your Mines probability of reaching that many safe tiles from the start, not the odds of the next pick alone.

Mines Multiplier Chart for 1, 3, 5 and 10 Mines

This Mines chart shows the multiplier and, in brackets, your chance of reaching that many safe tiles from the start. Mines odds and payouts are both worked out at a 1% house edge on a 25 tile board.

If a casino pays less than the chart at the same tile count, its edge is higher than 1%. The gap between two rows is the extra multiplier you earn for taking on one more pick.

How to Use a Mines Calculator

Set the mine count and the house edge, then read the multiplier and probability for each number of safe tiles. Three inputs are all you need.

1. Mine count. Choose how many mines the game uses, from 1 to 24.
2. House edge. Enter the edge the casino states, usually 1%.
3. Safe tiles. Find the row for the number of picks you plan to make, then compare its multiplier with the one the casino pays.

Stake Mines Calculator: Does It Match?

This calculator matches Mines games on a 5x5 board that run a 1% edge, which is how Stake and many other crypto casinos describe their version. Check the return the casino publishes before you rely on any calculator.

Compare one payout against the chart above. If the multiplier at the same mine count and tile count is lower, the casino is running a higher edge than the one you entered.

How Mines Multipliers Are Derived

A multiplier is one divided by the chance of surviving that far, with the house edge taken off. That is the whole calculation, and it means a casino cannot set payouts freely without changing its stated return.

On a 25 tile board with three mines, your first pick is safe 22 times in 25, which is 88%. Surviving two picks is 22 in 25 multiplied by 21 in 24, or about 77%. Invert that and take off 1%, and the two tile multiplier is roughly 1.29x.

Because the payout follows from the odds, a Mines game advertising a 99% return has no room to be stingier on one setting than another. Where the numbers do not match the table above, the edge is higher than 1%.

Why the Odds Are Not Independent

Every tile you open changes the odds of the next one, which separates Mines from dice or coin flip. Revealing a safe tile removes it from the pool, so the remaining mines are concentrated among fewer unopened squares.

With three mines on 25 tiles, your first pick carries a 12% chance of losing. By the time you have opened fifteen safe tiles, ten remain and three of them are mines, so the next pick loses 30% of the time.

That rising risk is why the multiplier curve steepens rather than climbing in a straight line. The payouts get dramatic precisely where the game gets dangerous.

Where to Cash Out in Mines

Every cash-out point has the same expected value, so there is no mathematically correct place to stop. The multiplier rises exactly as fast as your chance of reaching it falls, and the edge is applied evenly across the whole curve.

What changes is variance. Cashing at two or three tiles wins often for a small amount, and pushing toward the end of the board wins rarely for a great deal. Both give back the same fraction of what you stake over enough rounds.

The genuinely useful decision is the same one that applies at dice and crash. Set a session loss limit before you start, because that is the only choice here that changes an outcome.

Mine Count and Risk Compared

More mines means fewer safe tiles, sharper multipliers and a shorter run before the odds turn against you. These are the first-pick numbers at a 1% edge.

Run your own stake through the bankroll calculator to see how many rounds a bankroll survives at each mine count, and price the edge on every pick with the house edge calculator.

Mines Predictors and Hacks Do Not Work

No Mines predictor can tell you where the mines are, because the board is fixed by seeds you cannot see until the round is over. Tools that claim to predict it are either scams or guesses presented as software.

The server seed stays secret until you rotate, so there is nothing to predict from. The only check that works is the one that runs after the round, when you recompute the board from the revealed seed. Our provably fair guide shows how.

Verifying a Mines Round

Mines uses the same commitment scheme as the other originals, with the server seed published as a hash before you play. The digest seeds a shuffle that places the mines, so one hash determines the whole board.

Shuffle implementations differ between casinos, which is the usual reason a verification disagrees. Our provably fair guide covers where they diverge.

How to Verify a Mines Round Step by Step

The verifier above needs three values from the casino and nothing else. Follow these steps in order, because the hash check in step five is what proves the seed was not changed after you bet.

1. Before you bet, copy the hashed server seed from the casino's fairness panel.
2. Rotate your seed. The casino then reveals the unhashed server seed for the bets you made with it.
3. Copy your client seed and the nonce of the bet you want to check.
4. Paste all three values into the verifier above and run it.
5. Hash the revealed server seed with SHA-256 and confirm it matches the hash from step one. If it does not, the seed was swapped.
6. Compare the result with the one the casino showed. If only the result differs, check the casino's documented conversion before drawing any conclusion.

Worked Example With Test Seeds

Enter these placeholder values first to confirm the tool behaves as described. They are test seeds and do not come from any casino.

A match on the digest and the float means the verifier works. A match on the result as well means the casino uses the same conversion. Our provably fair guide explains where implementations diverge.

Best Mines Casino Bonuses

The multiplier is not the cost. Turnover is, and it is the multiplier applied to a base that varies by casino. The column below works out what clearing a $100 bonus actually requires at each mines casino in the register.

Check what clearing an offer costs with the wagering requirements guide and the cost-to-clear guide before you claim, and see the other crypto casino games we cover.

Two things inflate that figure further and neither is in the headline. Where terms say the requirement applies to deposit and bonus rather than bonus alone, the base doubles. And where slots count 100% toward clearing but table games count 10%, the same requirement takes ten times the turnover on blackjack.

Mines FAQs

How are Mines multipliers calculated?

Each multiplier is one divided by the probability of surviving that many picks, with the house edge deducted. The odds come from the board, so the payouts are derivable rather than chosen.

What is the best number of mines to play?

None is better in expected value terms. Fewer mines means frequent small wins, more mines means rare large ones, and both return the same fraction of what you stake.

When should you cash out in Mines?

Mathematically it makes no difference, because the multiplier rises exactly as fast as your chance of reaching it falls. Choose based on how much variance you want rather than on value.

What is the house edge on Mines?

Commonly 1% at crypto casinos running their own version. You can check by comparing a payout against the calculator above, since a higher edge shows up as a lower multiplier at the same tile count.

What is the probability of hitting a mine?

On your first pick it equals the mine count divided by 25, so three mines give a 12% chance. The chance rises with every safe tile you open, because fewer safe tiles remain.

What is the maximum multiplier in Mines?

With 24 mines, one safe pick pays 24.75x at a 1% edge. Other mine counts reach far higher multipliers only when you clear many tiles in a row, and the odds of doing so are small.

Is there a way to predict Mines?

No. The board is set by a server seed that stays hidden until you rotate seeds, so a predictor has no data to work from.

Is Mines provably fair?

Usually, at casinos running it as an original. The mine positions come from a shuffle seeded by a hash committed before you play.
