How to Play

Game Overview

BluffJudge 瞞天估局 is a party deduction game for 3-9 players that tests your acting skills, reasoning, and psychological tactics.

In each round, a "Judge" reads out a topic, while other players act as "Knowers" or "Bluffers," aiming to confuse the Judge and each other during the conversation.

Role Descriptions

👨‍⚖️ Judge

Goal: Identify the Bluffer

The Judge reads the topic and truth description, then listens to all players' conversations and answers. At the end of the round, the Judge must vote for the player they believe is the Bluffer.

Tip: Pay attention to details, reaction speed, and changes in speaking patterns.

🕵️ Knower

Goal: Help the Judge find the Bluffer

Knowers receive the truth description of the topic at the start of the game. They can freely answer the Judge's questions, aiming to appear authentic enough for the Judge to believe them.

Tip: Provide reasonable details and maintain a consistent story. The Bluffer will try to mimic your answer style.

🤥 Bluffer

Goal: Deceive the Judge into thinking you are a Knower

The Bluffer does not know the truth and must make up a story based on the Judge's questions and the Knowers' answers. The Bluffer needs to mimic the Knowers' style and maintain a consistent lie.

Tip: Listen carefully to the Knowers' details and stay consistent with your fabricated story. Contradictions will reveal your identity.

Tips & Strategy

As a Knower: Stay authentic and consistent, providing specific details. Watch for unnatural pauses or vague answers from the Bluffer.
As a Bluffer: Start looking for clues immediately, stay calm, and don't over-explain. Pay attention to specific vocabulary used by Knowers.
As a Judge: Don't just listen to the content; observe body language and reaction times. Look for contradictions.
Questioning Techniques: Mix simple and complex questions. Give specific hints or leads to see if both respondents take the bait.

FAQs

What if the Knower and Bluffer give the exact same answer?

This is perfectly legal and a great strategy! The Judge will need to ask deeper questions to find subtle differences.

Can I change my answer?

Yes, but it might raise the Judge's suspicion. Consistency is key.

Can the Bluffer ask for clarification on the Judge's question?

Certainly. The Bluffer should act naturally, just like a real Knower, which includes seeking clarification.

Quick-Start Guide: Your First Game

If you are new to BluffJudge, don't let the rules intimidate you. This is a game of intuition, acting, and social deduction. Here is a simple step-by-step guide to get you through your first round:

Setup: Gather 3 to 5 friends. Open the game on your device and enter everyone's names. We recommend that the person most familiar with the rules acts as the Judge for the first round.
Role Check: Each player takes turns looking at the screen. If you are the "Knower," make sure to memorize the key details in the "Truth" description. If you are the "Bluffer," quickly scan the "Hints"—these are your only tools for fabricating your story.
First Round of Speaking: The Judge will ask a simple opening question, such as: "Where would you typically find this?" The Knower should give a vague but accurate answer, while the Bluffer should observe the Knower's reaction and try to provide a plausible response.
Deepening the Conversation: The Judge will follow up based on the answers provided. This is the most exciting part of the game where players can question each other, debate, or even intentionally mislead the Judge.
Final Verdict: After hearing everyone speak, the Judge must make a decision. Remember, it's not just about who has the right facts, but who reacts most naturally under pressure.

Common Beginner Mistakes and How to Avoid Them

Based on hundreds of games, we have identified several common pitfalls for new players. Avoiding these will significantly increase your chances of winning:

Knowers: Being Too Specific Too Early.
If the topic is the "Eiffel Tower" and you immediately say "It's a tall iron tower in Paris," the Bluffer now has everything they need to mimic you perfectly. Instead, say something like "It's a world-famous landmark made of metal" or "It defines the skyline of a major European city." Give the Judge clues without giving the Bluffer the answer.
Bluffers: Ignoring the Hints.
The hints are your lifeline. If a hint is "History" and you are talking about "Modern Technology," the Judge will immediately sense something is wrong. Even if you don't know the truth, build your lie around the provided hints.
Judges: Voting Too Quickly.
Many Judges want to vote after just one round of questions. This often leads to mistakes. Bluffers are usually very careful in the first round; the real cracks appear in the second or third round of follow-up questions. Asking "Why?" can often trip up a Bluffer.
All Players: Ignoring Silence and Hesitation.
In BluffJudge, silence is information. If a player hesitates too long before answering or gives an extremely short response, it's often a sign that they are piecing together a lie in their head.

Example Dialogue: Good vs. Bad Plays

Let's look at the topic "Eiffel Tower" (Truth: A wrought-iron lattice tower in Paris; Hints: Paris, iron, landmark, height, tourist) to see how different roles perform:

❌ Poor Knower Performance

Judge: "What is a defining characteristic of this?"

Knower: "It's made of iron and it's in Paris."

Analysis: Too direct! The Bluffer now knows exactly what it is and can easily fabricate stories about tourism or its height.

✅ Excellent Knower Performance

Judge: "What is a defining characteristic of this?"

Knower: "It's an architectural marvel that was originally intended to be temporary, but it became a permanent symbol of its country's engineering."

Analysis: This provides enough info for the Judge to see you know the truth (architectural marvel, engineering symbol) without handing the "Paris" or "Iron" keywords to the Bluffer on a silver platter.

✅ Excellent Bluffer Performance

Judge: "Why do people visit this place?"

Bluffer (using the hint "Landmark"): "It's an iconic landmark that offers an incredible view of the surrounding area. It's one of those 'bucket list' items for any traveler."

Analysis: This sounds professional and plausible. Even though they don't know it's the Eiffel Tower, "iconic landmark" and "incredible view" fit perfectly with the hints and the general nature of famous sites.

Judge's Detection Tips: How to Become a Top Detective

As a Judge, you don't need to know the truth; you just need to know who is acting. Here are some advanced techniques:

Watch for "Mirroring": The most common Bluffer strategy is to repeat what the Knower said. If Player A gives a detail and Player B immediately uses different words to say the same thing, Player B is likely the Bluffer.
The Pressure Test: Suddenly turn to a player and ask a very specific, unexpected question, such as: "You mentioned the view; is it better at sunrise or sunset?" Observe their immediate reaction. A Knower might be confused (since the truth doesn't specify), while a Bluffer might try to invent a poetic answer.
Look for Logical Gaps: Bluffers often lose track of their own lies. If they say it's an "ancient structure" in round one but then say it's "modern and high-tech" in round two, you've found your target.
Body Language: If playing in person, watch for shifting eyes, touching the face, or unnatural posture. These physiological responses are very difficult to fake when under the pressure of a lie.

Advanced Tactics Teaser

Once you have mastered the basics, you can try more advanced strategies, such as:

The Double Mislead: A Knower intentionally gives a slightly incorrect detail to see if the Bluffer follows suit.
The Aggressive Bluffer: A Bluffer who takes the initiative to question the Knower, trying to flip the script and make the Knower look suspicious.
