🛡️ Provably Fair

Every result at Polygon Casino is generated from three values: a server seed (secret, its SHA-256 hash is shown before you bet), your client seed (you can change it any time) and a nonce (bet counter).

Random numbers = HMAC_SHA256(server_seed, client_seed:nonce:round). Each 32-byte output gives 8 floats between 0 and 1 (4 bytes per float). When you rotate your seed pair the old server seed is revealed, so you can check that its hash matches and recompute every past result with our verifier or your own code.

Rumus engine

• Dice: roll = floor(f₀ × 10001) / 100
• Limbo / Crash: result = floor(100 × RTP / (1 − f₀)) / 100 (min 1.00)
• Roulette: pocket = floor(f₀ × 37) (38 untuk Amerika, 37 = 00)
• Kartu (blackjack, baccarat, hi-lo): card = floor(fᵢ × 52), rank = card mod 13 + 1, suit = ⌊card / 13⌋
• Video poker, mines, keno, tower: Shuffle Fisher–Yates dengan fᵢ
• Plinko: setiap baris ke kiri jika fᵢ < 0.5, jika tidak ke kanan
• Slot: setiap sel adalah pilihan berbobot dengan fᵢ (gulungan demi gulungan, dari atas ke bawah)
• Wheel: segment = floor(f₀ × 30)
