Roobet Mines calculator
Roobet’s Mines is another hugely popular take on the crypto classic, and a “Roobet Mines calculator” lets you see exactly what each pick is worth before you make it. Set the number of mines and the safe tiles you intend to reveal below to get the multiplier, win probability and payout instantly.
Like every crypto Mines game, Roobet Mines runs on a 5×5 grid of 25 tiles, so this calculator models a Roobet round with the same accuracy it models any other. Only the house edge varies between sites — the multiplier maths and the odds are shared.

How Roobet Mines works
Roobet Mines drops a number of hidden mines — you choose how many — onto a 5×5 board. Each safe tile you uncover raises your multiplier; reveal a mine and the round is over. You can cash out your current payout at any point before that happens.
As with all provably fair Mines, the board is decided before you click, so the order you pick tiles in does not change the outcome — only how far up the multiplier ladder you climb before cashing out. That makes the true odds, not a “predictor”, the only thing worth studying.
Using this as a Roobet Mines calculator
Punch in the mine count and safe-tile target you would use on Roobet and the multiplier and win chance shown here apply directly. The payout uses SatoshiMines’ flat 1% edge, so it is exact here and a close estimate for Roobet, where the edge may differ slightly.
Prefer to play where you can check the fairness of every round yourself? SatoshiMines is a Bitcoin-native, provably fair home for the same Mines game, with that flat 1% edge and free credits to get started.
Want the underlying maths in full? The main Mines calculator breaks down the multiplier formula step by step, and the multiplier explainer works through the probability behind it. There is no predictor or pattern that beats a provably fair board — knowing the true odds is the only edge.
Roobet Mines calculator FAQ
Does this work as a Roobet Mines calculator?
Yes — Roobet Mines is the same 5×5, 25-tile game, so the multiplier and odds calculated here apply to a Roobet round. Only the house-edge-adjusted payout can differ slightly if Roobet’s edge isn’t the flat 1% used here.
How are Roobet Mines multipliers worked out?
For k safe tiles revealed on a 25-tile grid with m mines, the fair multiplier is the product of (25 − i) ÷ (25 − m − i) for i from 0 to k − 1, then trimmed by the house edge. The win chance is simply the reciprocal of that fair multiplier.
Is there a Roobet Mines predictor?
No. Roobet Mines is provably fair, so the mines are fixed by a seed before you pick and no predictor or hack can reveal them. The real odds — which this calculator shows for every step — are the only edge you can actually use.
What is a good Roobet Mines alternative?
SatoshiMines offers the same provably fair Mines game in Bitcoin, with a flat 1% house edge and free starter credits, so you can verify each round and play without depositing first.
