Mines is a grid game where you reveal safe tiles and avoid hidden mines. You may cash out after any safe reveal. One mine ends the round. The long-run cost comes from the operator's published house edge and payout formula, while the mine count you choose changes short-run bust risk.
Grid and mine count
Common builds use 25 tiles (for example a published 5×5 layout). You pick how many mines are hidden, often between 1 and 24 on that grid. Each safe reveal increases the offered cash-out multiplier. One wrong tile loses the stake.
Published operator RTP
Figures in the mines table come from operator-controlled pages in the originals research record. Empty gaps mean RTP Ledger could not fetch a published edge.

Survival probability (standard grid)
On a fair grid with M mines and T tiles, the chance the next pick is safe after k successful reveals (no cash-out yet) is (T − M − k) / (T − k) when 0 ≤ k < T − M.
| Safe reveals so far (k) | Next pick safe chance |
|---|---|
| 0 | 22/25 = 88.00% |
| 1 | 21/24 = 87.50% |
| 2 | 20/23 ≈ 86.96% |
This arithmetic describes mine placement risk only. The cash-out multiplier curve sets RTP together with the published edge. Related grid-style risk appears in Plinko path length and in keno hit tables.
Verification limits
Some operators publish mine placement as Fisher–Yates over a fixed tile pool. The provably fair guide explains what a recomputation proves. No legitimate verifier should claim to predict the next safe tile before the server seed is revealed.
Mines RTP FAQ
What is mines game RTP?
Mines RTP is the theoretical return on a mines grid game where you reveal safe tiles and cash out before hitting a mine. Published operator figures in RTP Ledger often show about 99% RTP (1% house edge) on several in-house builds.
How does mine count change risk?
More mines on the same grid raise the chance the next reveal hits a mine. RTP from the operator still comes from the payout curve and published edge, while mine count mainly changes volatility and bust frequency.
Are mines outcomes provably fair?
Several casinos document Fisher–Yates mine placement from published seeds. RTP Ledger documents Stake’s published mine event algorithm in the provably fair guide. Verification still does not predict the next tile.
Does cashing out after one safe tile change RTP?
Early cash-out changes how often you finish a round and how large the multiplier is. On a fixed published edge, that choice mainly changes volatility, not a free improvement in long-run RTP.
Higher mine counts increase bust frequency. RTP Ledger does not publish prediction tools or exploit instructions.
