+# Regicide - 单人卡牌游戏
+
+基于 Phaser 3 + boardgame-core 框架实现的 Regicide 合作卡牌游戏单人模式。
+
+## 游戏简介
+
+Regicide 是一款合作奇幻卡牌游戏，使用标准扑克牌进行游戏。玩家需要击败12个强大的敌人（4个J、4个Q、4个K）来取得胜利。
+
+## 游戏规则
+
+### 目标
+按任意顺序击败城堡牌堆中的所有12个敌人（J/Q/K）。
+
+### 设置
+- **城堡牌堆**: 12张敌人卡（4J、4Q、4K）
+- **酒馆牌堆**: 所有数字牌（2-10）和A
+- **初始手牌**: 8张
+- **小丑牌**: 2张（用于重抽手牌）
+
+### 敌人属性
+| 敌人 | HP | 反击伤害 | 分值 |
+|------|----|----------|------|
+| J    | 20 | 10       | 10   |
+| Q    | 30 | 15       | 15   |
+| K    | 40 | 20       | 20   |
+
+### 花色效果
+- **红桃 ♥**: 从弃牌堆回收卡牌到酒馆牌堆
+- **方片 ♦**: 抽取等量卡牌
+- **梅花 ♣**: 攻击力翻倍
+- **黑桃 ♠**: 减免反击伤害
+
+### 游戏流程
+1. **出牌阶段**: 打出一张或多张同点数的牌（总点数≤10）
+2. **伤害结算**: 对敌人造成等同于牌面点数的伤害
+3. **反击阶段**: 如果敌人未被击败，它会反击
+4. **抵消反击**: 弃置点数总和≥反击伤害的牌
+
+### 特殊规则
+- **敌人免疫**: 每个敌人免疫与其花色相同的卡牌效果
+- **组合牌**: 可打出多张同点数牌，但总点数不能超过10
+- **小丑牌**: 可弃光手牌并重新抽取8张（整局限用2次）
+
+### 胜利等级
+- 🥇 **金胜利**: 未使用小丑牌获胜
+- 🥈 **银胜利**: 使用1张小丑牌获胜
+- 🥉 **铜胜利**: 使用2张小丑牌获胜
+
+## 运行游戏

+
+## 技术栈
+
+- **Phaser 3**: 游戏引擎
+- **boardgame-core**: 状态管理（Preact Signals + Mutative）
+- **boardgame-phaser**: Phaser 集成框架
+- **Preact**: UI 组件
+- **TypeScript**: 类型安全
+- **Vite**: 构建工具
+- **Tailwind CSS**: UI 样式
+
+## 开发说明
+
+### 命令系统
+游戏使用 boardgame-core 的命令系统：
+- `setup` - 初始化游戏
+- `play <cardId>` - 打出单张卡牌
+- `combo <cardIds>` - 打出组合牌
+- `yield` - 放弃回合
+- `counterattack <cardIds>` - 反击时弃牌
+- `useJester` - 使用小丑牌重抽
+
+### 状态管理
+游戏状态使用 MutableSignal 响应式系统，通过 `game.produce()` 进行不可变更新。
+
+### 场景系统
+GameScene 继承自 GameHostScene，使用 `spawnEffect` 和 `effect()` 实现响应式渲染。

+# Regicide 快速入门指南
+
+## 🎯 游戏目标
+击败所有12个敌人（4个J、4个Q、4个K）
+
+## 🃏 出牌规则
+
+### 基本操作
+1. **点击手牌** - 出牌攻击敌人
+2. **反击时点击手牌** - 弃牌抵消反击伤害
+
+### 出牌方式
+- **单张牌**: 造成牌面点数伤害
+- **组合牌**: 多张同点数牌，总伤害=点数总和（需≤10）
+- **放弃**: 不出牌，直接承受反击伤害
+
+### 花色特效
+- ♥ 红桃 - 回收弃牌
+- ♦ 方片 - 抽取新牌  
+- ♣ 梅花 - 伤害翻倍
+- ♠ 黑桃 - 减免反击
+
+## ⚔️ 敌人信息
+
+| 敌人 | 生命值 | 反击伤害 |
+|------|--------|----------|
+| J    | 20 HP  | 10       |
+| Q    | 30 HP  | 15       |
+| K    | 40 HP  | 20       |
+
+**注意**: 每个敌人免疫与其花色相同的卡牌效果！
+
+## 🃏 小丑牌
+- 可以**弃光手牌**并**重新抽取8张**
+- 整局限用**2次**
+- 使用次数影响胜利等级
+
+## 🏆 胜利等级
+- 🥇 金: 未使用小丑牌
+- 🥈 银: 使用1张小丑牌
+- 🥉 铜: 使用2张小丑牌
+
+## 💡 游戏提示
+1. 合理使用花色特效
+2. 保留高点数牌应对强敌
+3. 注意敌人的花色免疫
+4. 谨慎使用小丑牌
+
+祝你好运，勇者！⚔️
