Mines pattern generator

It draws a random 25-tile layout in your browser. The Random pattern panel shuffles the positions 0–24, marks the first batch as mines, the next batch as diamonds and leaves the rest unmarked. The multiplier beside the board comes from the page's own 99% RTP formula for the two counts you set — 2.00x at the opening 3 mines and 5 diamonds. No casino feed is read and nothing is uploaded.

No. A live Mines board is derived from the casino's server seed, your client seed and the bet's nonce: Shuffle's provably-fair documentation draws the mine positions from HMAC-SHA256 floats mapped onto the 25 spaces of the board, and says that while a game is active the server seed stays hashed, so neither player nor operator can read it. This page shuffles tiles with the browser's own Math.random and never touches those inputs.

No. The chance of clearing a set number of tiles depends on how many mines sit on the board and how many tiles you reveal, not on where the marks land. With 3 mines, five safe reveals work out at 49.57% whichever of the 25 positions the shuffle picked, and the panel prints the same 2.00x for every one of those layouts.

Because the diamond count is also a reveal count. The figure is what the same 99% RTP formula returns for clearing that many safe tiles on a board holding that many mines — 0.99 divided by the probability that every reveal misses a mine. The arrangement never enters it, so 3 mines and 5 diamonds reads 2.00x on every shuffle. The full grid of combinations is on the Mines calculator.

They are the tiles the shuffle left blank — 25 minus the mines minus the diamonds — and the line under the board counts them, reading "3 mines · 5 diamonds · 17 unmarked" at the opening settings. In a live round every tile that is not a mine is safe, so the diamonds here stand for the tiles you would choose to reveal and the unmarked ones for safe tiles left covered.

Mines 1 to 24, diamonds 0 to 24, and the two counts together no more than 25. Anything else is refused rather than trimmed: both number boxes shake with a red border for about half a second and the panel reads "Need 1–24 mines and 0–24 diamonds that fit on 25 tiles." The board keeps the layout it already had, and the multiplier falls back to the counts of that last valid pattern.

5148297.00x, at 12 mines with 13 diamonds — or 13 mines with 12 — which is every safe tile on the board cleared. That figure is the tool's own arithmetic, and the cash such a multiplier could return is capped separately: Shuffle limits a single Mines round to $500,000 with a $20,000 maximum bet, and says a bet whose size and multiplier together exceed that cap cannot be placed.

Each press of Generate runs a Fisher–Yates shuffle of all 25 positions, taking its numbers from the browser's Math.random, so every position has the same chance of being drawn as a mine. That source is pseudorandom rather than cryptographically secure — the scripts call no Web Crypto function — so a layout is a practice board, not a recorded casino round.

Not from this page. Generate calls the shuffle with no seed argument, so each press takes a fresh draw from Math.random, and neither the layout nor a seed is written to browser storage or into the URL. Copy or screenshot a layout you want to keep. The underlying function does accept an integer seed for repeatable output, but the interface exposes no field for one.

The calculator does the maths; this page draws one arrangement of it. The Mines calculator takes mines, gems revealed and a bet, then returns multiplier, win chance and payout, with a clickable grid and a full 24 × 24 payout table. The pattern generator takes mines and diamonds and returns a single random 25-tile board plus the same multiplier — no win chance, no bet field, no table.

The board does. Shuffle's documentation describes "the 25 tiled mines board" with its spaces numbered 0 to 24, and our verifier implements Stake and BC.Game Mines on the same 25 tiles with 1 to 24 mines. How each casino derives a layout differs: BC.Game shuffles a fixed 25-value permutation twice, where Stake and Shuffle draw positions one at a time from HMAC-SHA256 floats.

Only for bets you can already verify. The Mines Pattern Finder on our provably-fair verifier takes your client seed and a revealed server seed, lets you click the tiles that must be mine-free, and scans up to 10,000 nonces for a board that fits, for Stake, Shuffle or BC.Game. A server seed is only revealed once you rotate the pair, so it reaches settled bets only.

No. After the page loads, the counts, the shuffle and the rendered board exist only in that browser tab — the generator makes no network request and writes nothing to browser storage, so a layout is gone once you reload. The multiplier is arithmetic done in the same script, not a lookup. Every calculator on the tools hub works this way.
