Gamdom Mines Calculator

The verified multiplier check

In a live round with 2 mines and 5 safe picks, the game displayed a multiplier of x1.5632, with x1.7368 next. Fair math for that spot is C(23,5) / C(25,5) = 0.6333 survival, so the fair multiplier is 1.5789.

1.5632 ÷ 1.5789 = 0.990. The next step checks out the same way: 1.7368 ÷ 1.7544 = 0.990. Every displayed multiplier is the fair value multiplied by exactly 0.99 — a classic 1% house-edge payout table.

Where the missing 1% goes

Gamdom's zero-edge program returns that 1% as instant rakeback on the first $5,000 wagered per day. Within the allowance, your effective long-term return is 100% — but it arrives as a separate credit, not inside the round payout.

Per Gamdom's own terms: after the daily limit is fully used, a 1% house edge applies to all bets (99% RTP) until the next reset. The bet limit is $500,000; the daily zero-edge allowance is $5,000 wagered.

The top multiplier

The highest-paying standard target is a 24-mine board cleared for its single safe tile: fair math prices it at 25.00x, and the 99% table pays 24.75x.

Where the cap starts

$2,500,000 ÷ 24.75 ≈ $101,010. Any bet above roughly $101,000 on that configuration hits the win cap before it hits the full multiplier.

What a max bet really pays

At the $500,000 maximum bet, the cap limits the realizable multiplier to 5.00x — regardless of what the payout table shows. High rollers face a very different effective table.

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.

What the panel proves

Because the server seed hash is committed before your first click, Gamdom cannot change a board 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.

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.

Mind the allowance and the cap

Within the $5,000 daily allowance your effective return includes the 1% rakeback; beyond it, the 99% table is the full story. For large bets, check the $2,500,000 cap math above.

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. The possible return can be large, but the path to reach it is mathematically fragile — and above ~$101,000 bets, capped.
