## FC3D Basic Rules / 福彩3D基础规则|

### 玩法说明|

| 玩法 | 规则 | 奖金 | 概率 |
|------|------|------|------|
| **直选** | 三位数字与开奖号码完全一致（顺序相同） | 约1040元/注 | 1/1000 |
| **组选3** | 三位数中两个数字相同，不计顺序与开奖号码一致 | 约346元/注 | 3/1000 |
| **组选6** | 三位数字各不相同，不计顺序与开奖号码一致 | 约173元/注 | 6/1000 |
| **直选和值** | 三位数字之和等于目标和值（覆盖该和值全部号码）| 按覆盖注数计 | 按和值注数 |

- 每注金额：**2元**
- 开奖时间：每天一期，约21:15公布
- 号码范围：百位、十位、个位各取0-9|

## 12 Analysis Algorithms / 12大分析算法|

### Algorithm 1: Frequency Heatmap / 频率热力分析|

**原理**：统计各位（百/十/个）每个数字(0-9)在历史开奖中出现的次数和频率。|

**分类标准：**
- 🔥 **热号**：出现频率 > 平均频率×1.2
- 🌡️ **温号**：出现频率在平均频率±20%区间内
- 🧊 **冷号**：出现频率 < 平均频率×0.8|

### Algorithm 2-12 Summary|

| # | 算法 | 核心思路 | 推荐策略 |
|---|------|---------|---------|
| 2 | 遗漏值分析 | 遗漏值=间隔期数，冷号回补 | 搭配1-2个极冷号（遗漏>20）|
| 3 | 奇偶比分析 | 三位数字奇偶组合 | 优选「两奇一偶」或「一奇两偶」（合计75%）|
| 4 | 大小比分析 | 0-4为小，5-9为大 | 优选「两大一小」或「一大两小」（合计75%）|
| 5 | 和值分析 | 百位+十位+个位，范围0-27 | 黄金区间10-17（约52%概率）|
| 6 | 跨度分析 | 最大值-最小值，范围0-9 | 优选跨度5-7（约52%）|
| 7 | 012路分析 | 除以3余数分类 | 避免某路数字全部缺失 |
| 8 | 质合比分析 | 质数vs合数 | 与奇偶、大小联合过滤 |
| 9 | 重号分析 | 三位是否存在相同数字 | 主攻组选6型（无重号，72%）|
| 10 | 连号分析 | 三位是否存在连续数字 | 可覆盖一组连号组合 |
| 11 | 号码形态矩阵 | 奇偶+大小+质合三维过滤 | 三维缩水 |
| 12 | 蒙特卡洛+多维过滤 | 随机生成+多条件过滤 | 高质量候选注数 |

### Monte Carlo Python Code / 蒙特卡洛Python代码|

```python
import random

def fc3d_filter(hundreds, tens, units):
    """福彩3D多维过滤函数"""
    nums = [hundreds, tens, units]
    # 1. 奇偶比过滤（排除全奇全偶）
    odd_count = sum(1 for x in nums if x % 2 == 1)
    if odd_count == 0 or odd_count == 3: return False
    # 2. 大小比过滤（0-4小，5-9大）
    big_count = sum(1 for x in nums if x >= 5)
    if big_count == 0 or big_count == 3: return False
    # 3. 和值过滤（10-17黄金区间）
    if not (10 <= sum(nums) <= 17): return False
    # 4. 跨度过滤（5-7优选）
    if not (5 <= max(nums)-min(nums) <= 7): return False
    return True

def monte_carlo_fc3d(n_output=10):
    results = []
    while len(results) < n_output:
        nums = [random.randint(0,9) for _ in range(3)]
        if fc3d_filter(*nums):
            results.append(nums)
    return results
```
