How it works

A murder mystery party on one screenand a phone per player

The Last Signal is a cooperative murder mystery party game built around two screens: the shared screen — a TV or laptop everyone can see — is the room you're investigating, and every player's own phone is their character, holding the secrets only they know. Neither is enough alone.

What you need

One shared screen

A TV, monitor or laptop with a browser — it plays the room.

A phone per player

Any modern phone browser. One character per phone.

Six minutes of setup

Host picks a story, players type the room code. That's it.

How a game night runs

  1. The host picks a story

    On the shared screen, the host chooses a story and a difficulty. Every story carries a timing guide the whole room can see, so you always know how far through the night you are.

  2. Phones join with a room code

    The shared screen shows a six-character code. Each player opens the site on their phone, enters the code, picks a name, and is assigned a character. No app, no accounts, nothing to install — it all runs in the browser.

  3. The shared screen is the room

    The TV or laptop shows the scene everyone is in: the storm-lit locations, a sweeping torch that the room controls together, evidence as it reaches the board, and the act's clock. Everyone at the table sees the same room.

  4. Each phone is a character

    Your phone holds things only you can see: private clues you found, sealed tasks, and your own suspicions. Clues on the shared board are public — but a clue in your pocket is yours until you choose to share it, which is where the real party conversations start.

  5. Investigate, interview, and vote

    Between scenes you compare notes, sweep locations for evidence, and — in some stories — question a witness together. The witness has a limited budget of answers shared across the whole table, so you decide as a group which questions are worth it. When the evidence is laid out, everyone makes their accusation.

  6. The dawn reveal

    After the vote, the host walks the room through what actually happened: the verdict, how everyone voted, the true sequence of the night, and what each character contributed. Private material stays private — the debrief reveals what was earned, not what was hidden.

Why the second screen matters

Most party mysteries hand everyone the same booklet. Here, information is split on purpose: the shared screen shows what the group discovers together, while each phone holds a private layer of clues and intentions. To solve the mystery you have to talk to each other — and decide what to hold back. Play solo and the empty roles are filled by companions the game runs for you; play with up to five and every secret at the table belongs to a real person.

Questions party planners ask

How many players do you need?
One to five human players. Solo, the game runs your character's companions for you; with a full table, every role is a person.
Does anyone need to download or install anything?
No. The shared screen and every phone use the browser. The host creates a room, players join with the six-character code, and you're in.
How long does a story take?
The pilot story runs five acts at roughly 30–45 minutes, with a pacing timeline visible to the whole room so you can pace your evening.
Is it competitive?
It's cooperative: the room wins or loses together on the final accusation. The secrets and private objectives are there to create debate, not to declare a single winner.
