Rainbet Mines Calculator
Use this Rainbet Mines calculator to estimate payout, profit, survival odds, bust risk and multipliers. The 96% preset reproduces the live payout math — a figure we verified in-game on every one of the four selectable board sizes.
Rainbet Mines calculator: payout, odds and multiplier
The widget uses the shared MinesCalc engine with the default set to 96% RTP, so the adjusted values match the multipliers shown on the live 5x5 table — the numbers a player actually sees on screen.
Fair multiplier = 1 / P
Rainbet-style estimate = Fair × 0.96
Rainbet Mines Calculator
Choose bet size, mines, safe picks and RTP to compare odds, payout, profit and multiplier estimates against the live 5x5 table.
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.

What this calculator shows
The tool covers the questions players actually bring here: payouts, the chart and table views, odds, multipliers and RTP. It is an independent math reference, not an official Rainbet tool.
Payout estimates
Enter a bet amount to estimate gross payout and net profit for the selected mine count, safe-pick target and RTP setting.
Odds and bust risk
The odds output shows the chance of reaching the selected number of safe picks before hitting a mine. Bust risk is the opposite side of the same setup.
Multiplier math
The multiplier starts from survival probability. With the 96% preset, the estimate matches the live payout values before rounding.
Table view
The table view helps compare cashout depths without recalculating each setup manually. Always compare estimates with the live game display.
Check the live Mines table on Rainbet
The game pays from a clean 96% multiplier table on every board size — a figure this page verified against ten live readings. Before playing, pick your board, compare the live multipliers against the estimates above, and remember that a larger board changes the odds, not the pricing.
Rainbet Mines RTP: 96%, verified on every board size
Rainbet does not print an RTP figure on its game page, and secondary catalogs circulate 96.5%. So we read the number straight from the live game on July 10, 2026: ten multiplier points across all four boards, every one of them equal to fair math × 0.96.
| Board | Setup (2 mines) | Fair multiplier | Fair × 0.96 | Shown in-game |
|---|---|---|---|---|
| 5x5 (25) | 4 gems | 1.4286x | 1.3714x | 1.37x |
| 5x5 (25) | 5 gems | 1.5789x | 1.5158x | 1.52x |
| 5x5 (25) | 7 gems | 1.9608x | 1.8824x | 1.88x |
| 5x5 (25) | 8 gems | 2.2059x | 2.1176x | 2.12x |
| 6x6 (36) | 4 gems | 1.2702x | 1.2194x | 1.22x |
| 6x6 (36) | 5 gems | 1.3548x | 1.3006x | 1.30x |
| 7x7 (49) | 5 gems | 1.2431x | 1.1934x | 1.19x |
| 7x7 (49) | 6 gems | 1.3023x | 1.2502x | 1.25x |
| 8x8 (64) | 10 gems | 1.4088x | 1.3525x | 1.35x |
| 8x8 (64) | 11 gems | 1.4630x | 1.4045x | 1.40x |
Four board sizes: how 6x6, 7x7 and 8x8 change the math
Rainbet is the only version among those we have verified that lets you pick the board: 25, 36, 49 or 64 tiles. The pricing rule stays fair × 0.96 everywhere; what changes is the probability side. The general formula is P = C(N − M, s) / C(N, s), where N is the board size.
Same mines, safer clicks
Two mines on 64 tiles are much easier to dodge than two mines on 25. That is why 10 gems at 8x8 pay only 1.35x, while 7 gems at 5x5 already pay 1.88x.
Bigger boards, slower curves
A larger board stretches the multiplier curve: each safe pick removes a smaller share of the remaining tiles, so growth per click is flatter and deep runs take longer.
How to model non-5x5 boards
The calculator on this page models the 25-tile board. For 36, 49 or 64 tiles, apply the general formula above with the 0.96 factor — the verification table shows worked examples for every size.
Odds model: how mine count shapes risk
The odds here follow the same 25-tile probability model used by the general Mines calculator. Mine count and safe-pick target define the chance of reaching a cashout point.
Mine count sets the risk curve
A lower mine count gives each click a higher chance of being safe, but the multiplier grows more slowly. A higher mine count creates faster multiplier growth and higher volatility.
Safe picks compound risk
Each safe pick changes the remaining board. The calculator measures the cumulative chance of reaching the selected safe-pick target, not just the chance of the next tile.
Bust risk is the inverse view
If the survival chance is 40%, the bust risk before that target is 60%. The calculator keeps both numbers visible so the payout is not evaluated in isolation.
Assumptions used by this calculator
This page defaults to the 25-tile board with 96% RTP, matching the pricing verified in the live game on every board size. Custom RTP stays available for modelling other assumptions.
Fairness: what the "provably fair" badge covers
The live game carries a fairness badge, and Rainbet's page states that provably fair technology backs every round. As always, the scheme proves the past, not the future.
What verification proves
When a board is committed before your first click, the casino cannot change it after seeing your picks. After a seed rotation you can recompute finished rounds and confirm they matched the commitment.
What it does not enable
The unrevealed server seed cannot be recovered from its hash, so no tool can compute future boards from the fairness data. The full reasoning — with an interactive demonstration — is on the Mines Predictor & Hacks page, and the verification walkthrough is on Provably Fair Mines.
How to use the calculator
Start with mine count
The mine count controls the risk curve. Fewer mines create a higher chance of surviving each click and slower multiplier growth.
Choose a cashout target
The safe-pick target is the number of safe tiles you want to reveal before cashing out. Each additional safe pick increases payout and lowers the chance of reaching that target.
Pick the board deliberately
Board size is a risk control of its own: the same mine count plays very differently on 25 and 64 tiles. Choose the board first, then set mines and the cashout target.
Risk profiles by mine count
Low mine count
With fewer mines, the multiplier grows slowly because the selected path is easier to survive. Shallow targets on the 99% table produce modest payouts with frequent wins.
Medium mine count
A middle setup shows the trade-off clearly: each extra safe pick raises the payout while compounding the chance of ending the round on a mine.
High mine count
High mine counts create sharp multiplier jumps because the survival window is narrow. On larger boards the same effect needs proportionally more mines — 2 mines on 8x8 is a low-risk setup, not a high-risk one.

FAQ
What RTP does Rainbet Mines use?
96%. Rainbet does not publish the figure on its game page, so we verified it in-game on July 10, 2026: ten multiplier readings across all four boards each equal fair math × 0.96.
Is the 96.5% figure from casino catalogs correct?
Not according to the live game. Every multiplier we checked computes to exactly fair × 0.96 — a 4% house edge. The 96.5% value circulating in aggregator catalogs is not confirmed by any in-game reading.
What board sizes are available?
Four: 5x5 (25 tiles), 6x6 (36), 7x7 (49) and 8x8 (64), selectable before each round. The pricing factor is the same 0.96 on every board; only the probabilities change with size.
What RTP does this calculator use?
The default preset is 96%, matching the verified live pricing, and it models the 5x5 board. For larger boards, apply the general formula P = C(N − M, s) / C(N, s) with the same 0.96 factor — worked examples are in the verification table above.
Can this calculator predict safe tiles?
No. It cannot predict safe tiles, reveal mine positions, decode future rounds or bypass the game. Boards are generated server-side before your first click; the math of why no tool can beat that is demonstrated on the Mines Predictor & Hacks page.
What are the bet limits and maximum win?
Rainbet does not publish exact figures; its page says limits suit both casual players and high rollers, and we checked the game at $0.10 stakes. Confirm current limits and any win cap in the in-game info panel for your currency.
Why can live values differ from this calculator?
Rounding (the live display rounds to two decimals), possible win caps, board-size selection, currency-specific limits or interface updates. Always compare with the live game screen before playing — and note the in-game "profit" label shows total return, not net profit.
