🛡️ 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.

엔진 공식

• 다이스: roll = floor(f₀ × 10001) / 100
• 림보 / 크래시: result = floor(100 × RTP / (1 − f₀)) / 100 (min 1.00)
• 룰렛: pocket = floor(f₀ × 37) (아메리칸은 38, 37 = 00)
• 카드 (블랙잭, 바카라, 하이로우): card = floor(fᵢ × 52), rank = card mod 13 + 1, suit = ⌊card / 13⌋
• 비디오 포커, 마인즈, 키노, 타워: fᵢ를 이용한 Fisher–Yates 셔플
• 플링코: 각 줄에서 fᵢ < 0.5이면 왼쪽, 아니면 오른쪽
• 슬롯: 각 칸은 fᵢ를 이용한 가중 추첨 (릴별로 위에서 아래로)
• 휠: segment = floor(f₀ × 30)
