How to Play

Full rules for all six games. Jump to any of them below.

๐Ÿš€ The Crew

Overview: A real-life version of the hidden-impostor genre. Most players are Crewmates completing tasks; a smaller number are secret Impostors trying to blend in and take the group down without getting caught.

Objective
Crewmates: complete every task, or find and eject every Impostor. Impostors: equal or outnumber the remaining Crewmates.
Players
4โ€“10 recommended, minimum 3.
Setup
Add every player's name, set the minimum and maximum number of Impostors, and optionally add a task checklist. Each player privately taps through the app to see their role.

Gameplay

  1. Crewmates work through their task checklist during normal party activity.
  2. Impostors quietly fake the same checklist to blend in.
  3. Anyone can hit the buzzer to call an Emergency Meeting โ€” for suspicion, or because someone was "caught."
  4. The group discusses out loud, then votes to eject a suspect.
Winning
Crewmates win the instant every task is completed, or once every Impostor is ejected/eliminated. Impostors win if they ever equal or outnumber the remaining Crewmates.

Tips

  • Keep the task list short for faster games โ€” 3 to 5 tasks works well for most groups.
  • Give each crewmate only a subset of tasks instead of the full list for a longer, less predictable game.

๐Ÿ”ช Mafia

Overview: The classic night-and-day social deduction game, with roles you define yourself. The phone privately runs every night action, so there's never a human "narrator" who knows everyone's secrets.

Objective
Town: eliminate every Mafia member. Mafia: equal or outnumber the Town.
Players
5โ€“12 recommended, minimum 3.
Setup
Add players, then define roles: a name, a team (Town or Mafia), an optional night action (Kill, Save, or Inspect), and how many of that role to include. Unassigned players become plain Villagers.

Gameplay

  1. Everyone privately learns their role during the reveal phase.
  2. At night, everyone closes their eyes. By default, the phone privately visits every player in turn โ€” even ones with nothing to do โ€” so no one can tell who has powers just by who gets called up.
  3. Mafia members privately agree on a shared kill target. Doctor-type roles privately choose someone to protect. Detective-type roles privately investigate someone's team.
  4. At dawn, the app reveals who (if anyone) died. Discuss out loud, then vote publicly to eliminate a suspect โ€” their role is revealed.
Winning
Town wins when every Mafia member is eliminated. Mafia wins the moment they equal or outnumber the surviving Town.

Tips

  • For a first game, keep it simple: one Mafia, one Doctor, one Detective, rest Villagers.
  • The "everyone gets a turn" night setting is slower but keeps the game fair for longer โ€” worth it for sharper groups.

๐ŸฆŽ The Chameleon

Overview: A category and a secret word are chosen. One player โ€” the Chameleon โ€” sees the category but not the word, and has to bluff a convincing clue anyway.

Objective
Everyone else: catch the Chameleon without letting them guess the word. Chameleon: avoid detection, or guess correctly if caught.
Players
3โ€“8 recommended, minimum 3.
Setup
Add players and pick which built-in word categories to use, or write your own. Each round picks a random category, a random secret word, and a random Chameleon.

Gameplay

  1. Everyone privately sees the secret word (or, for the Chameleon, just the category grid).
  2. In turn order, each player says one word or short clue related to the secret word โ€” specific enough to prove they know it, vague enough not to give it away.
  3. After everyone's spoken, discuss out loud and vote for who you think the Chameleon is.
Winning
If the real Chameleon is caught, they get one public guess at the word โ€” guessing right steals the win back. If they're not caught, they win automatically. Scoring: Chameleon win = 2 points; everyone else wins = 1 point each.

Tips

  • Write your own category if the built-in word lists feel too easy or too hard for your group.
  • As the Chameleon, a slightly vague but plausible clue works better than an overly specific guess.

๐Ÿ•ต๏ธ Secret Missions

Overview: No rounds, no voting โ€” everyone gets a private social task to complete sometime during the party, and quietly checks in on their own progress whenever they want.

Objective
Complete your mission without getting noticed doing it.
Players
3 or more.
Setup
Add players and choose which built-in missions to include, or write your own โ€” some target a specific other player, others can be completed with anyone.

Gameplay

  1. Everyone privately learns their mission during the reveal phase.
  2. Missions run in the background for as long as the party lasts โ€” there are no turns.
  3. Check in privately anytime (same pass-and-hide pattern as the reveal) to mark your mission Completed or Caught.
  4. Whenever the group is ready, end the game to reveal every mission and status at once.
Winning
Scoring only: Completed = +2 points, Caught = โˆ’1 point, never attempted = 0.

Tips

  • Run this alongside another game โ€” it doesn't need everyone's full attention.
  • Mix open and targeted missions so no single type of mission gives away who has one.

๐Ÿงจ Bomb Pass / Infection

Overview: Two fast, high-energy modes under one game. Bomb Pass is a hot-potato elimination game; Infection is a hidden-spreader tag game.

Objective
Bomb Pass: be the last player standing. Infection: as Patient Zero, quietly infect as many players as possible before time runs out.
Players
3 or more for either mode.
Setup
Bomb Pass: set a min/max explosion window in seconds. Infection: set a round length in minutes.

Gameplay โ€” Bomb Pass

  1. Everyone stands in a circle. The phone arms a hidden timer that will go off at a random, unknown moment.
  2. Pass the phone hand to hand around the circle.
  3. When it explodes, whoever's holding it is out. Arm the next round with whoever's left.

Gameplay โ€” Infection

  1. Everyone privately checks their status โ€” one random player is secretly Patient Zero, everyone else is clean.
  2. Set the phone down as a stationary timer. Patient Zero discreetly tags others to infect them; tagged players can keep spreading it.
  3. When time's up, everyone reveals whether they're infected.

Tips

  • Bomb Pass works best with music playing to add urgency.
  • For Infection, agree in advance what counts as a valid "tag" so there's no dispute mid-game.

๐Ÿ’ฃ Two Rooms and a Boom

Overview: Two secret teams split across two physical rooms, trading hostages each round while a President and a Bomber try to steer the outcome.

Objective
Bomber's team: get the President into a room where their team has the majority by the end of the game. President's team: avoid exactly that.
Players
4 or more โ€” you'll need two separate rooms or spaces to actually play.
Setup
Add players, set the number of rounds and minutes per round. The app splits everyone into two teams and assigns one President and one Bomber.

Gameplay

  1. Everyone privately learns their team, role (if any), and starting room, then physically splits into two spaces.
  2. Each round has a timer. Each room privately discusses and agrees on who to send to the other room as hostages โ€” the number required goes up each round.
  3. Carry the phone to each room in turn to record the picks. The exchange happens at the same time โ€” sent players physically swap rooms.
Winning
After the final round, check the President's room. If their team's opponents (the Bomber's team) have more people there, the bomb goes off and that team wins. Otherwise, the President's side wins.

Tips

  • Keep the two rooms far enough apart that neither can overhear the other's discussion.
  • The Bomber's goal isn't to hide โ€” it's to maneuver the President into the wrong room by round's end.
