How the evening goes
InvitePick language, world and length, name the players. Everyone gets a link and tells us who they are, optionally with a photo. After three days at the latest your mystery and its trailer are ready.
Connect the phonesThe host shows each person their own QR code. Scan, you're in. Nobody sees anyone else's cards.
InvestigateEvery round opens with a played scene with a picture and a narrator. Then you read your secret card on your phone and see three leads. Phones away: for 15 to 20 minutes you question each other. Then you vote on a lead and anonymously tap who did it. From round 2 the opening shows what the chosen lead found.
AccuseAt the end everyone accuses. Solution, points and leaderboard, rate the story. The host plays too and does not know the solution.

You stay yourselves, with your names, roles and quirks. Only the place changes.






















What makes it different
Everyone has a secret
Each person gets one they would rather keep, and a reason they look suspicious tonight. Confess and you are cleared. Keep quiet and you score.
Play, don't read
Three minutes on the phone, then 15 to 20 minutes of talking, asking, confronting. Then you decide where the investigation goes.
Written for you
Your places, rituals and quirks live inside the motives, secrets and clues. From your photos the AI draws your characters.
Fair to the end
Every revelation comes with a picture. The solution follows from clues that were on the table. Not even the host knows it.

A murder mystery game with nothing to print
A classic murder mystery kit has fixed characters and one solution for everybody. Here the story is made fresh, with your names, quirks and secrets. There is nothing to print, cut out or read aloud. One phone per person is enough.
Murder mystery for companies, team events and Christmas dinners
As a team event or company party, a murder mystery gets people talking who rarely sit at the same table. The story takes up roles, places and in-jokes from your team. It suits a Christmas dinner, a team evening or an outing, for 3 to 12 people.
Murder mystery for a birthday
For an adult birthday the game fills the part of the evening between the aperitif and dessert. The birthday person can play too, because even the host does not know the solution. If you like to dress up, use the costume ideas that come with the story.
Detective game for a child's birthday
For children and families there is the child mode: nothing violent, and instead of a murder something goes missing and the kids find out who took it. A detective game for a children's birthday or a family evening, played on the phones and in conversation.
