1win Mines Calculator
Use this 1win Mines calculator to estimate survival odds, bust risk, payout and profit for this version of the game. The 94% RTP preset on this page is not taken from marketing copy — it was derived and cross-checked against all eleven multipliers published in the game interface.

Choose bet size, bomb count and safe picks to estimate the chance of reaching a cashout point, the bust risk and the 94% RTP-adjusted multiplier. The engine is the same one used across MinesCalc; only the preset changes.
Fair multiplier = 1 / P

Calculated values are mathematical estimates. Real casino values may differ because of rounding, RTP settings, max-win caps, bonus rules or platform-specific payout tables.

The last column reproduces the interface rounding rule, so it matches the multiplier strip shown in the game one to one.

How the 94% RTP was verified
The game interface publishes a multiplier strip for the selected bomb count. Dividing each published value by the fair mathematical price of the same target gives the implied return, and a single consistent rule should explain every entry. It does.
Eleven values, one rule
All eleven multipliers displayed at 3 bombs — from 1.06x at one pick to 5.93x at eleven — match the formula fair × 0.94 truncated to two decimals, without a single exception.
Alternatives ruled out
The same test rejects 93%, 95% and 96%: each of those rates fails on at least one published value. The implied returns cluster tightly between 93.3% and 94.0%, exactly the spread truncation produces around a true 94%.
Rounding is downward
The interface truncates rather than rounds, which shaves up to 0.01x off each value. The effective return is therefore marginally below 94% — a small, honest footnote most version reviews miss.
How the 1win version differs
Only four bomb settings
The selector offers four fixed settings, from 2 up to 7 bombs — no single-bomb low-volatility mode and none of the extreme 10–24 bomb setups found in other builds. The risk range is deliberately narrow.
Lower RTP than most versions
At a derived 94%, the return sits below Roobet's 96%, Spribe's 97% and the 99% in-house builds. On identical setups, estimated multipliers here are the lowest in the cluster.
A currency cap, not a multiplier cap
The win limit is $50,000,000 in currency. The effective multiplier ceiling equals that amount divided by your bet — at everyday stakes it is unreachable, even on a full 7-bomb clear worth about 451,858x.
| Version | RTP used on MinesCalc | Mine / bomb range |
|---|---|---|
| 1win in-house | 94% (derived) | 2 / 3 / 5 / 7 |
| Roobet | 96% | 1–24 |
| Spribe (provider) | 97% | 1–20 |
| Stake in-house | 99% | 1–24 |
| BC.Game in-house | 99% | 1–24 |
| Duel | 100% up to limits | 1–24 |
Bet limits and payouts
The published game rules define the wagering boundaries reproduced below. Payout equals bet multiplied by the reached multiplier; a bomb before cashout ends the round and forfeits the bet.
Provably fair in the 1win version
Hash first, salt after
The board layout is generated server-side at round start and committed as a hash. After the round, the hash is stored in your bet history together with a salt, and the pair can be checked in the built-in verifier or any third-party hash calculator.
Verification looks backward
The scheme lets you confirm a finished round was not altered mid-play. It does not leak anything about boards that have not been played — the general mechanics are covered on the Provably Fair Mines page.

FAQ
What RTP does 1win Mines use?
The derived figure is 94%: every multiplier published in the game interface at 3 bombs equals the fair price multiplied by 0.94 and truncated to two decimals. Competing rates of 93%, 95% and 96% fail that test.
How many bombs can be set in the 1win version?
Four options: 2, 3, 5 or 7 bombs on a fixed 5x5 board. Other builds usually allow anywhere from 1 to 24.
Why is the game multiplier lower than the fair value in the calculator?
Two effects stack: the 94% return setting and downward rounding to two decimals. For example, five safe picks at 3 bombs have a fair price of 2.0175x, while the game shows 1.89x.
What is the maximum win?
$50,000,000 in currency, with bets accepted from $0.10 up to $1,000,000. The multiplier itself is not capped — the ceiling is the currency amount divided by your bet.
Is the game provably fair?
The version commits a hash of the round layout at the start and reveals the salt in bet history afterwards, so completed rounds can be verified. Verification confirms the past; it cannot predict future boards.
Why do estimates here differ from the Stake or Spribe pages?
Different presets: this page models 94% with truncation and a 2/3/5/7 bomb selector, while other pages apply 99% or 97% with wider mine ranges. Identical targets therefore price differently on each page.
