Somebody at your Halloween party is a murderer.

Four to ten guests play suspects. At a bigger party the next six play witnesses: named characters with a costume and a secret, who saw something and cannot be the guilty one. Anyone beyond sixteen, and anyone who would rather not act, plays a detective: they question the suspects and vote at the end. Up to 40 phones can join one party.

Yes. After you pay, choose "Buying this for someone else?" and send them the host link. Whoever opens it first becomes the host. You can still join their party as a guest.

The story still works. Every mystery is written so the important clues never depend on a guest who might not come. If a guest with a key character leaves, another player takes that character over with one tap. Late arrivals join as detectives.

No. They open a link or scan a QR code and type their first name. It runs in the phone's web browser.

No. Characters, clues and voting are all on the phones. If you have a TV, you can put the evidence on it for the whole room.

No. The app deals the characters and keeps the answer hidden until the reveal, so the host plays like everyone else. The host might even be the culprit.

In the two Halloween mysteries, no. Each has three possible culprits, and the game picks one when your party starts. The evidence everyone sees is the same each time. The private clues and the ending change, so a guest who has played before cannot be sure. The other mysteries have one culprit each.

Yes. They are written with AI. Software then checks each one: for every possible guest list, every innocent suspect can be cleared and the clues point to one culprit. The ready-made mysteries are also given to AI test readers one round at a time, without the answer, to see whether they can be solved. The About page has the details.

About an hour with up to eight suspects: three rounds of 12 to 15 minutes, then the vote and the reveal. With a full table of ten suspects and six witnesses, allow about 75 minutes. The host moves things along, so you can stretch it over dinner or keep it quick.

Yes. The Case of the Missing Marrow is free for 4 to 6 players and takes about 34 minutes. No payment and no account: start it from the Free mystery page and share the link. It is shorter and simpler than the full mysteries, which play with up to 16 characters.

Yes. Every mystery has its own page and its own buy button, and you get the one you pick. Nothing is random. If you change your mind before your party starts, the host screen lets you swap to another ready-made mystery at no cost.

The family mysteries have no murder, nothing scary and short, simple clues. They work well from about age 7, with a grown-up nearby to help younger readers. The grown-up mysteries are PG-13: a comic murder, no gore.

One party: a private party code, every character and clue for up to 40 guests, the host controls and the reveal. It is one payment for the whole group, not per person. You can swap to a different ready-made mystery free of charge any time before your first game starts.
