🛡️ 可证明公平

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.

引擎公式

• 骰子: roll = floor(f₀ × 10001) / 100
• Limbo / Crash: result = floor(100 × RTP / (1 − f₀)) / 100 (min 1.00)
• 轮盘: pocket = floor(f₀ × 37) (美式轮盘为 38，37 = 00)
• 纸牌（21点、百家乐、猜高低）: card = floor(fᵢ × 52), rank = card mod 13 + 1, suit = ⌊card / 13⌋
• 视频扑克、扫雷、基诺、Tower: 使用 fᵢ 进行 Fisher–Yates 洗牌
• Plinko: 每一行若 fᵢ < 0.5 则向左，否则向右
• 老虎机: 每个格子都是基于 fᵢ 的加权抽取（逐轴、从上到下）
• 转盘: segment = floor(f₀ × 30)
