Mines has the shortest rulebook in Tonza Originals: a grid of tiles, a chosen number of hidden mines, and one decision repeated over and over — open another tile or take the money. What confuses people is the payout curve. Three mines move the multiplier by pennies, fifteen mines pay more than 2x on the very first tile, and both numbers fall out of one formula.
The round, step by step
You set two things before the deal: the stake and the mine count, which is yours to pick. The layout is locked when the round starts and does not react to where you click, because the arrangement is already baked into a result you can verify afterwards.
A safe tile raises the multiplier. A mine ends the round and the stake is lost. The payout is the stake times the current multiplier, and Originals accept stakes from 0.1 to 10000 in your account currency.
Where the multiplier comes from
A multiplier is an inverted probability with the house edge taken out. On a board of N tiles holding m mines, the chance of opening k safe tiles in a row is a ratio of combinations: p = C(N − m, k) / C(N, k). The multiplier is the game's RTP divided by that probability, and Mines on Tonza runs at a stated 98% RTP, so the coefficient comes to roughly 0.98 / p.
The figures below use a 25-tile board to keep the arithmetic concrete. They illustrate the formula rather than reproduce a paytable, so read the grid and the coefficients off the game in front of you. Three mines, three tiles opened: p = (22/25) × (21/24) × (20/23) ≈ 0.6696, and 0.96 / 0.6696 ≈ 1.43.
The same formula produces a detail worth noticing. With a single mine on 25 tiles the first safe tile pays just 1.02x, because the chance of avoiding it is 24/25, or 96%, and the margin consumes almost all of it. The curve only starts climbing on the second tile.
Mine count, streak length and expectation
Theoretical multipliers on that 25-tile board at 98% RTP, rounded.
| Mines | 1 tile | 3 tiles | 5 tiles |
|---|---|---|---|
| 1 | 1.02 | 1.11 | 1.23 |
| 3 | 1.11 | 1.46 | 1.98 |
| 5 | 1.23 | 1.98 | 3.36 |
| 10 | 1.63 | 4.95 | 17.34 |
| 15 | 2.45 | 18.78 | 206.6 |
Growth is exponential in both directions, because the survival odds collapse just as fast. Reaching five tiles with fifteen mines on the board is roughly a 1-in-211 event, and the payout reflects that rather than rewarding it.
Every combination of mine count and cash-out point returns the same expected value: 98% of the stake. One mine cashed at 1.11x, fifteen mines chased towards 207x — identical expectation, completely different session.
What changes is variance. Low mine counts give frequent small wins and the occasional painful loss. High counts give long droughts punctuated by rare big hits. A good run on one setting tells you nothing about the other, and the same bankroll behaves nothing alike under the two regimes.
Verifying the layout
Mines is provably fair. Before the round the server publishes a hash of its seed, you can set your own client seed, and the mine positions are derived from both seeds plus a nonce that counts the rounds. Afterwards the server reveals its seed and the board can be recomputed by hand, which is what proves the layout was fixed before the first click. The provably fair page walks through the procedure.
What a strategy can and cannot do
Rules such as always open three tiles, or double after a loss, leave the round's math untouched; they redistribute outcomes over time and nothing more. Martingale is a particularly bad fit here, since with a high mine count losing streaks are routine and the sequence reaches the stake ceiling or the end of the balance long before it turns.
The one real decision is when to stop, and it selects a risk profile rather than a return. A structurally different case is PvP duels, where the stake goes against another player instead of a paytable. The rest of the catalogue is under all games.
