TL;DR
- Default 3-mine Mines: clearing all 22 safe tiles pays 2,477.7x with a 1-in-2,300 probability.
- At 24 mines, a single safe tile pays 24.75x with a 4% hit rate.
- The 1% house edge is constant at every mine count and every cashout point.
2,477.7x. That is the multiplier for clearing all 22 safe tiles on Stake Originals Mines at the default 3-mine configuration. The probability of reaching it without triggering a mine: 1 in 2,300. The same game at 24 mines has a single safe tile paying 24.75x with a hit rate of 1 in 25. The configurable mine count is what makes Mines the most flexible originals game in the catalogue.
Cash out early at low mine counts. The multiplier curve is slow and the EV inversion point arrives before most players expect it.

Mines house edge at every mine count and every cashout point. EV = stake x 0.99 always.
The Multiplier Formula
The multiplier at Mines after n successful reveals with m mines placed on a 25-tile grid is:
Multiplier = 0.99 x C(25, n) / C(25 - m, n)
Where:
- C(a, b) = a! / (b! x (a-b)!): the binomial coefficient
- n = number of safe tiles revealed so far
- m = number of mines in the game
- 0.99 = the factor that embeds the 1% house edge
The multiplier grows faster when more mines are in play, because each reveal has a higher probability of hitting a mine and surviving becomes more valuable in EV terms.
House edge verification: at any cashout point, EV = P(surviving to n reveals) x multiplier x stake = stake x 0.99. The 1% house edge is constant across all mine counts and all cashout points.
Multiplier Curves by Mine Count
3 Mines (Default): 25 Tiles
| Reveals (n) | Multiplier | Probability of reaching this point |
|---|---|---|
| 0 (start) | 1.00x | 100% |
| 1 | 1.13x | 22/25 = 88.0% |
| 2 | 1.28x | (22x21)/(25x24) = 77.0% |
| 3 | 1.47x | 67.00% |
| 5 | 2.18x | 50.40% |
| 7 | 3.54x | 37.70% |
| 10 | 9.31x | 23.90% |
| 15 | 78.06x | 9.48% |
| 20 | 2,477.7x | 1.52% |
| 22 (all safe) | 2,477.7x | 1/2,300 = 0.0435% |
Cashout at reveal 20 (5 safe tiles remain) pays 2,477.7x with a 1.52% probability of reaching that point. Clearing the final 2 tiles to "all safe" reduces the probability to 1/2,300 (0.0435%) with the same 2,477.7x payout. The EV of the final two reveals is neutral. The marginal variance is extreme.
The most important number in this table is not the 2,477.7x. It is the 88.0% probability on the first reveal. That is the first reveal working as expected value says it should. The multiplier at 1.13x barely covers stake. Most players see this and keep going. The curve accelerates slowly; 9.31x at reveal 10 still carries a nearly 1-in-4 chance of termination. The patience required to reach 15 reveals (78.06x) is real.
5 Mines: 25 Tiles
| Reveals (n) | Multiplier | Probability of reaching |
|---|---|---|
| 1 | 1.24x | 20/25 = 80.0% |
| 3 | 1.97x | 55.00% |
| 5 | 5.07x | 35.80% |
| 8 | 18.71x | 18.50% |
| 10 | 50.91x | 11.30% |
| 12 | 171.8x | 6.44% |
| 15 | 1,551.9x | 2.60% |
Five mines accelerates the multiplier curve. The 50.91x at 10 reveals with 5 mines compares to 9.31x at 10 reveals with 3 mines: nearly 5.5 times the multiplier for a meaningfully higher per-step risk.
At 5 mines the break-even variance shift occurs around reveal 8-10. Reaching 18.71x (reveal 8) requires surviving 8 consecutive successful reveals against 5 mines on a 25-tile grid. The survival probability drops from 80% on the first reveal to 18.5% for the full run to reveal 8. Session bankroll erosion happens quickly when mine-hit frequency increases.
24 Mines: 1 Safe Tile
| Reveals (n) | Multiplier | Probability |
|---|---|---|
| 1 (only possible) | 24.75x | 1/25 = 4.0% |
At 24 mines, a single safe tile remains. One reveal pays 24.75x. The probability of finding it: 1 in 25 (4%). This is the highest-risk, highest-single-step multiplier configuration. The EV is 0.99, consistent with the 1% house edge.
The 50,000x Max Win: Szymool's $600K
The 50,000x maximum win on Stake Mines requires very high mine counts combined with an extended streak. Szymool's documented $600,000+ win involved high mine counts and a long survival streak; the specific bet details are in the Stake bet history. At high mine counts, the multiplier per successful reveal increases rapidly, and each additional reveal compounds the multiplier geometrically.
The probability of the specific combination of mine count and streak that produces a 50,000x outcome is in the single-digit millionths per session. The win is real. It happened. It is verified on-chain. It is the upper tail of a known distribution, and the distribution produces results like it once in millions of bets.
The Szymool win is not a strategy template. It is a data point.
On 24 May 2026, a Stake Mines player recorded a $788,980.50 USDT payout. The win is logged in the verified big wins feed at /casino/big-wins/. The bet is on-chain. The house edge on every game played before and after that session was 1.00%.
Probability of Clearing All Safe Tiles
P(clear all) = C(25-m, 25-m) / C(25, 25-m) = 1 / C(25, 25-m)
| Mine count (m) | Safe tiles | Probability of clearing all | Odds (1 in) |
|---|---|---|---|
| 1 | 24 | 1/C(25,24) = 1/25 | 25 |
| 3 | 22 | 1/C(25,22) = 1/2,300 | 2,300 |
| 5 | 20 | 1/C(25,20) = 1/53,130 | 53,130 |
| 10 | 15 | 1/C(25,15) = 1/3,268,760 | 3,268,760 |
| 15 | 10 | 1/C(25,10) = 1/3,268,760 | 3,268,760 |
| 24 | 1 | 1/C(25,1) = 1/25 | 25 |
C(25,22) = C(25,3) = 25!/(3! x 22!) = (25 x 24 x 23)/(6) = 2,300.

Mines Variants
Stake Originals Mines (Reference)
25-tile grid, 1-24 mines, multiplier formula 0.99 x C(25,n) / C(25-m,n). 1% house edge. Full provably fair verification. Cashout available at any point after the first reveal.
Thrill.com Mines Variant
Thrill's implementation differs from Stake in specific payout curves. The house edge and provably fair mechanics are comparable, but multiplier steps at specific reveals are calibrated differently. Check Thrill's published game maths before switching strategies from Stake.
Third-Party Mines (e.g. Spribe)
Third-party versions are RNG games, not provably fair, with house edges typically between 2-5%. The mechanics are similar, but the maths are not equivalent to Stake Originals at 1%.
The Single Biggest Mistake: Cashing Out Too Late on Low Mine Counts
At reveal 20 on a 3-mine game, any further reveal has a 3/5 chance of hitting a mine for a marginal multiplier increase. The EV of those final reveals is mathematically neutral. The risk is not.
At low mine counts (1-3 mines), the multiplier curve is slow and the risk-to-reward ratio favours early cashout. At 3 mines, consider reveals 15 to 22: at reveal 15, the multiplier is 78.06x with a 9.48% probability of reaching that point. Continuing from reveal 15 to the full clear at 22 requires surviving 7 more reveals, each reducing the probability by one remaining-safe-tile fraction.
Many players continue because the multiplier "only needs a few more reveals." The EV of those final reveals is mathematically neutral. The risk is not. It is concentrated in a narrow range where mine exposure is highest. Cashout at 10-15 reveals on a 3-mine game consistently outperforms chasing the full clear across many sessions.
Responsible Gambling
Mines at 1% house edge is one of the best-value casino games in the catalogue. High mine counts and deep reveal chains create large potential losses in a single session. Set a session budget. Decide your cashout point before you start.

FAQs
- Does the mine placement change based on how many tiles I have already revealed?
No. Mine positions are fixed at the start of the game by the provably fair seed combination. They are placed before your first click, not adaptively after your choices. You cannot influence mine placement by revealing in a specific order or pattern.
- Is 3 mines or 5 mines better value?
Both run 1% house edge: the EV per session is identical in expectation. The choice is about variance. Three mines has a slower multiplier curve, longer expected survival run, and smaller but more frequent typical cashout. Five mines accelerates the multiplier faster but increases mine-hit probability per reveal.
- What is the lowest stake available on Stake Originals Mines?
The minimum stake is $0.01. At $0.01 per game, you can run hundreds of sessions before material losses accumulate, making it the most accessible originals game for learning the multiplier curve without significant exposure.
- Can I see where the mines are before I cash out?
No. Mine positions are revealed only when you hit a mine or cash out. At cashout, the full board is revealed consistent with the provably fair seed. You cannot see or predict mine positions during active play.
