📖 Game rules

How well do you know your friends?

In Mystery Crew you answer questions about yourself in secret, and the others guess what you picked. You guess their answers too. Here are the full rules, in short.

The whole thing in a minute

  1. CrewCreate a group (friends, your partner, family or a class) and invite the others with a code or a link.
  2. Secret answersAnswer short questions about yourself. Nobody sees your answer.
  3. GuessingIn rounds, you guess each other’s answers. After your guess, the answer is revealed.
  4. Daily MysteryEvery day someone in the crew is the Mystery. Work out who it is from the clues.
  5. XP, streak, leaderboardEvery good guess earns XP. Find out who knows the others best.

1. The crew

The crew is your group. When you create it, you choose who you play with: friends, partner or family. Each crew has a 6-character invite code and an invite link. Anyone who gets it can join and start playing straight away.

2. Secret answers about yourself

On the Play tab you get short questions about yourself, e.g. “Where would you rather go? Seaside, mountains, big city, theme park”. Pick your answer and you’re done. Your answer is secret. It’s only revealed after the others have guessed.

Questions come from a bank of more than 500. With a Crew Pass, the crew can also write its own questions; everyone answers them, even without a Pass.

The more questions you answer, the more rounds can start about you, and the more clues there will be about you in the Daily Mystery.

3. Guessing rounds

Rounds are built from answers people have already given. There are two kinds:

🎯 What did they pick?

“What did Ben pick: seaside or mountains?” Everyone guesses except Ben, who already knows. After your guess, his answer is revealed.

🙋 Who said this about themselves?

A yes/no question, e.g. “Are you often late?” Tap everyone you think said yes. There can be more than one right answer.

When does a round close?

There’s no timer: everyone plays on their own phone at their own pace, so you don’t need to be together at the same time.

4. Who in the crew…? The secret vote

Roughly every fourth question is about the crew: “Who’s the funniest?”, “Who would you go on holiday with?” The options are the crew members, and you pick one in secret.

5. The Daily Mystery

Every day someone in the crew is the Mystery. Only the server knows who.

  1. CluesThe clues come from the Mystery’s own secret answers, e.g. “☀️ Summer” for “Which season is yours?”. They open one at a time.
  2. One guessWhen you think you’ve got it, make your guess. You get one guess a day, so think it through.
  3. The revealYou find out who it was, and how many in the crew got it right.

The fewer clues you need, the more XP you get. Even a wrong guess earns a little XP for taking part.

If you are today’s Mystery, you can’t guess. You can see which clues the crew got about you, and how many have guessed. Can you keep quiet? 🤫

6. Question of the day

Every day there’s one shared question that’s the same for every player, not just your crew. Answer it and predict what most people will pick. The next day you find out whether you were right, and how many people thought the same.

7. XP, levels, streaks, leaderboards

⚡ XP and level

You earn XP for good guesses, the Daily Mystery, voting and playing every day. Your XP adds up to your level.

🔥 Streak

Play every day and your streak grows, with bonus XP every week. The crew also has a shared streak: at least two of you need to play each day, or it runs out.

🏆 Leaderboard

Weekly, monthly and all-time leaderboards inside the crew. Who knows the others best?

🎫 Crew Pass

Seasonal rewards (avatars, frames, badges) and custom questions for your crew. It gives no advantage in the game, and the game is complete without it. Every Pass is free until 30 November.

8. Bonus: the “How well do you know me?” quiz

Once you’ve answered 5 questions about yourself, your own quiz is ready. Send it to anyone or post it to your story. People can take it in the browser, without downloading anything, and you see how well each of them knows you.

FAQ

Who can see my answers?
Only your crew, and only in the game: they are revealed one by one after guessing. In votes, nobody sees who you voted for, unless that person guesses it. In a class crew, the teacher only sees the totals (how many picked each answer), not who picked what.
Is it free?
Yes, downloading and playing are free. The Crew Pass (€2.99 / season) only adds extras. Every Pass is free until 30 November, and it’s not a subscription: nothing is charged afterwards.
Do I need to sign up?
No, you can play as a guest. In that case your XP and crews live only on that phone. Link your account to Google or Apple and nothing is lost when you change phones.
What if someone writes a nasty question?
Custom questions go through a profanity filter. Anyone can report one with the 🚩 button: it disappears for them right away, and for everyone after two reports.
Can we play without phones?
The app runs on iPhone and Android. Two things work in a browser, without installing anything: the “How well do you know me?” quiz, and a teacher’s quiz link, which students can take in the computer room or on a laptop.
Can I play with a school class?
Yes, with the Teacher Crew Pass, from year 7 (age 12+). The teacher is the game master: they write the questions, start rounds and see the results. For teachers →
