The Midnight Cake Mystery午夜蛋糕之谜
B1 Speaking Game · 说英语游戏🍰 The Case 案件
Last night someone ate the whole birthday cake in the school kitchen! 🎂 Be a detective. Ask your classmates questions in English to find out:
WHO 谁 did it · WHERE 哪里 they hid · WHAT 什么 they used
📖 游戏说明（中文）
这是一个 “大侦探”推理游戏。昨晚，有人把学校厨房里的整个生日蛋糕吃光了！🎂
你要当侦探，用英语向同学提问，找出三件事：
🕵️ 是谁干的（WHO） · 🏠 藏在哪个房间（WHERE） · 🔦 用了什么（WHAT）。
每人用自己的电脑加入同一局：输入相同的游戏码和相同顺序的名单，再选“我是谁”。 你的屏幕会显示几张秘密卡牌——这些卡不是答案，而是帮你排除嫌疑人（别人看不到你的屏幕）。 关键：答案就是没有人手里有的那 3 张牌，所以别人手里的每张牌都可以划掉。
按顺序轮流：轮到你时，用英语大声说出你的猜测（例如 “I think it was Miss Rose, in the Library, with the Flashlight.”）， 然后问下一位同学：“Do you have any of these cards?” 对方必须用英语回答——有就只给提问的人看那张牌，没有就说 “No, I don't have any.” 一边玩一边在侦探笔记上打勾（✓ 安全 / ✗ 排除）。 第一个正确说出“谁 + 哪里 + 什么”的人获胜！🏆

Everyone plays on their own laptop but joins the same game. Just type the same Game Code and the same list of names. 每人用自己的电脑，输入相同的游戏码和名单，就能加入同一局。
- Teacher picks a Game Code (any word) and reads out the class list, in order. 老师选一个游戏码，并按顺序念出名单。
- Everyone types the same code and the same names, then chooses "I am ___". 大家输入相同的码和名字，再选“我是___”。
- Your laptop shows your secret cards. They are NOT the answer — the answer is the 3 cards nobody was dealt (one suspect, one room, one object were hidden as the crime). So the game is about marking SAFE (✓) every card you can prove is in a hand. 你的电脑显示你的秘密牌。它们不是答案——答案是没发给任何人的那 3 张牌（一名嫌疑人、一个房间、一件物品被藏起当作作案组合）。所以游戏就是把能证明在别人手里的牌全部标为安全（✓）。
- On your turn, say a guess out loud in English — a suspect + room + object — and ask the next player: "Do you have any of these cards?" You're not guessing randomly; you're testing those 3 cards to see if they're in someone's hand. 轮到你时，用英语大声说出猜测（嫌疑人＋房间＋物品），并问下一位：“Do you have any of these cards?” 你不是乱猜——你是在测试这 3 张牌是否在别人手里。
- What the answer means 👉 YES = they show you one card (only you see it) → it's in a hand → mark it SAFE (✓), it can't be the crime. NO = none of the 3 are theirs → ask the next player, and keep going around the circle. 回答的含义👉 YES＝给你看一张牌（只有你看）→ 在别人手里 → 标为安全（✓），不可能是答案；NO＝这 3 张都不在他手里 → 问下一位，继续绕圈。
- How you find the answer 🎯 When a card goes all the way around and nobody can show it (and it isn't in your own hand), it must be part of the crime. When only one suspect, one room and one object are left without a ✓, you've solved it — first to name that WHO + WHERE + WHAT wins! 🏆 怎么找出答案🎯 当某张牌绕一圈都没人能出示（也不在你手里），它就是作案的一部分。当每类都只剩一张没打✓时，你就破案了——第一个说出这个“谁＋哪里＋什么”的人获胜！
2–6 players. Everyone must type the names in the same order. 2–6 人，顺序必须一致。
🔁 Turn order 出牌顺序
When the current player finishes, anyone taps this to pass the turn — so player 2, 3… know they're up. Everyone keeps it in step over the call. 当前玩家说完后，点这个把回合传给下一位，让 2 号、3 号…知道轮到自己了。大家在通话里保持同步。

These are NOT the answer — they help you rule people out. Others can't see your screen. 这些不是答案，用来排除。别人看不到你的屏幕。
🔎 Build your guess 组装你的猜测
If they say "No", ask the next player, and keep going around the circle until someone shows you a card. 如果他说 No，就问下一位，绕圈一直问，直到有人给你看一张牌。
🧠 How the detective logic works 侦探逻辑（重要） ▾
The big secret 🔑: the answer is the 3 cards that NOBODY has. Before the game, one suspect, one room, and one object were taken out and hidden — that's the crime. Every other card was dealt to a player. So any card in someone's hand cannot be the answer. 最大的秘密🔑：答案就是没有人手里有的那 3 张牌。开局前，一名嫌疑人、一个房间、一件物品被取出并藏起——这就是作案组合；其余每张牌都发给了玩家。所以，凡是在别人手里的牌，都不可能是答案。
So the game is elimination: prove which cards are in hands and mark them SAFE (✓ green) in your notebook. Whatever is left without a ✓ in each group must be the answer. 所以整个游戏就是排除法：证明哪些牌在别人手里，就在笔记里把它们标为安全（✓ 绿色）。每一类中最后没打✓的那一张，就是答案。
✅ Someone shows you a card → it's in their hand → NOT the answer → mark it SAFE (✓ green). 有人给你看牌 → 在他手里 → 不是答案 → 打✓（绿色，安全）。
❌ Someone has none → those 3 cards aren't in their hand → ask the next player. 某人一张都没有 → 这 3 张不在他手里 → 问下一位。
🎯 You go all the way around and no one can show a card (and it's not in your hand) → that card is the answer! 绕一圈都没人能出示（也不在你手里）→ 那张就是答案！
Smart moves 聪明技巧: Your own cards are already ruled out — mark them ✓. Mix a card you know with cards you're unsure about, so you learn exactly which one a player is hiding. Watch what others show, too. Only make a Final Accusation when just one suspect, one room, and one object are left. 你自己的牌已排除（打✓）。把已知的牌和不确定的牌混着问，就能判断别人藏的是哪一张；也要观察别人给谁看了什么。只有每类都只剩一张时，再做最终指控。
🗣️ When someone asks YOU 当别人问你
❌ No, I don't have any of them. 没有，我一张都没有。
If you have one of the 3 cards, tell only the asker which one (say it quietly / in a private chat). 如果你有其中一张，只告诉提问的人。
🕵️ My Detective Notebook 我的侦探笔记 ▾
This is your thinking sheet. As you learn things, tap a card's mark. Tap the same mark again to clear it. 这是你的思考表。学到新线索时点一下卡片的标记；再点同一个标记可取消。
How to use it 🧭: Your own cards start green ✓ (safe) automatically. Every time a player shows you a card, mark it ✓. When a whole group — Suspects, Rooms, or Objects — has only one card left without a ✓, that card must be part of the crime! 🎯 怎么用🧭：你自己的牌一开始就是绿色 ✓（安全）。每次有人给你看牌，就打 ✓。当某一类（嫌疑人／房间／物品）只剩一张没打 ✓ 时，那张就是作案的一部分！🎯
