How the result is calculated
float[i] = HMAC_SHA256(server_seed, "client_seed:nonce:cursor"), 4 bytes per number 0 ≤ f < 1 Tile order: for i = 0…23 take float[i] and pick position floor(float[i] × (25 − i)) among the tiles not yet picked. The first N picked positions are mines. Tiles are numbered left to right, top to bottom: 0…24. Multiplier after k safe tiles = 0.99 × C(25, k) / C(25 − N, k).
How to play
- Choose your bet and the number of mines — 1 to 24.
- Press “Play” or just click any tile — the round starts with your current bet.
- Every safe tile raises the multiplier. Its value shows right on the revealed tile.
- “Cash out” pays bet × multiplier. Hit a mine and the bet is lost.
- After a round, click the grid to play again with the same bet. You can change the bet and mines anytime; changes apply from the next round.

RTP 99%: multiplier = 0.99 ÷ the probability of revealing that many safe tiles in a row. Bet up to $10,000 ÷ multiplier, at most $5,000. The rail stops at the last step that is still no higher than ×10,000, and the round closes with a payout.
