獎勵層級是純數學！已添加到智能合約： fn calculate_reward(luck: u8, random: f64, price: u64) -> u64 { let thresholds = get_thresholds(luck); match random { r if r <= thresholds.dud => 0, r if r <= thresholds.rebate => price / 2, r if r <= thresholds.even => price, r if r <= thresholds.profit => price * 3 / 2, _ => price * 5, // 頭獎 } } 更高的運氣 = 更好的門檻 = 更多的勝利 ...隨機數字是不可觸碰的
