Sus Party
Open Game

How to Play

Phones guide it. The game happens in your house.

Sus Party is a real-world social deduction game. Crewmates move between rooms finishing physical tasks. Intruders blend in, eliminate people quietly, and try to survive the vote. If you have played Mafia or Among Us, this is the live-action version.

Short version: move, do tasks, watch people, call meetings, vote carefully.

The 30-second version

Everyone walks around the house doing real-life tasks on their phone. Players write the task list themselves at the start (Quiplash style), so every game is different. A few players are secretly intruders trying to sabotage and "kill" the rest. Find a body? Call a meeting, argue, vote someone out. Crew wins by finishing every task or voting out all intruders. Intruders win by surviving and thinning the crew.

  • Crew: do your tasks, stay alert, debate hard in meetings.
  • Intruder: blend in, fake tasks, "kill" by tapping a player's card on your phone when you're alone with them. Watch out: intruders also get ability cards that can tilt the game in their favor.
  • Meetings: anyone alive can call one. Talk it out, vote, eject. The ejected player is out for the round.

That's the whole game. Everything below is just detail.

Before You Start

Good setup does most of the teaching for you.

New players understand the game much faster when the host points out the space first: where meetings happen, where tasks happen, and whether meltdown mode is on.

Meeting area

Pick one central room where everyone returns when a meeting is called. A living room, kitchen, or other easy gathering point is ideal.

Task list

Make a list of short physical tasks around the venue. Players mark them complete on the honor system after they actually do them.

Optional reactor

If you want meltdown mode, put a laptop in a different room from the meeting area. People should have to travel to reach it.

Good first-game setup

  • Use 5 to 16 players. Around 8 to 12 usually feels best.
  • Keep tasks short, obvious, and spread across several rooms.
  • Make sure every player has a phone and knows how to swipe a task complete.

Explain these two rules out loud

  • Intruders kill by tapping a player and quietly telling them they are dead.
  • If you die, wait for the next meeting. When the meeting starts, your phone will show an "I'm Dead" button — you MUST press it then. The game tracks deaths from that button, and skipping it breaks scoring and end-game logic.

Roles

Every player gets a secret job.

Your phone tells you whether you are a Crewmate or an Intruder. Keep that role private.

Crewmate

Keep the house moving and catch the killers.

Crewmates spend the game finishing tasks, staying alive, and building enough suspicion to vote intruders out.

  • Follow the task on your phone and do it in real life.
  • Swipe when you finish to get the next task.
  • Notice who was where, who was alone, and who is acting strangely.
  • Report bodies or call a meeting when something feels off.
Intruder

Blend in long enough to thin the crew.

Intruders look like normal players, but their goal is to quietly remove crewmates and stay alive through the meetings.

  • Walk with purpose and fake the rhythm of doing tasks.
  • Eliminate isolated players without witnesses.
  • Use cards to sabotage, misdirect, or pressure the crew.
  • Win by numbers or by forcing a successful meltdown.

Round Flow

The loop is simple once people understand the rhythm.

Most of the game is just alternating between moving around the house and gathering in one room to talk about what happened.

1

Move and do tasks

Crewmates see one task at a time on their phones. Go to the location, do it in real life, then swipe to confirm it. Intruders should copy that rhythm and look busy.

2

Kill quietly or find a body

If an intruder catches someone alone, they can tap that player and quietly tell them they are dead. Anyone who finds the body can call a meeting.

3

Return to the meeting area

When a meeting is called, everyone heads back to the central room. Do not start debating early. Wait until the phones say the meeting is live.

4

Discuss, vote, and repeat

Living players vote for one person or choose veto or skip. If nobody is ejected, everyone goes back out and the loop starts again.

The game feels best when people stay disciplined about the quiet periods and the meeting area.

Critical dead-player rule

If you are killed, stay quiet and leave your body where it was. You cannot mark yourself dead yet. The next time a meeting is called, your phone will show an "I'm Dead" button — you MUST press it during that meeting. The game uses that button to track who is alive, and forgetting it breaks voting, win conditions, and the end-game summary.

Meetings

Meetings are the whole game, so keep them clean.

The tension lives here. A good meeting is clear, timed, and honest about who is alive, dead, and ready to vote.

What happens during a meeting

  • Everyone goes to the meeting area and gets quiet.
  • Living players press Ready. Dead players confirm that they are dead.
  • Discussion starts and is usually timed to about 3 minutes.
  • Then the living players vote.

How ejection works

  • The top vote-getter is only ejected if they also clear the host's vote threshold. By default that is about two thirds of living players.
  • If more than half of living players choose veto or skip, no one is ejected.
  • Ties also mean no ejection.
  • After the meeting, surviving intruders may draw more cards, so stalled games get harder.
Important

If you are unsure, a veto is usually better than ejecting a crewmate by mistake.

Optional Meltdown

Meltdown is not required, but it makes the game much better.

Meltdown gives the crew a time pressure event and gives intruders a way to force movement, panic, and bad decisions.

How it starts

An intruder can trigger meltdown by physically triggering it at the reactor or with a sabotage card. When that happens, players receive a 4-digit code on their phones and have to move fast.

How to stop it

  • Everyone with a code rushes to the reactor laptop.
  • Codes have to be entered before time runs out.
  • The normal target is around 60% of living players within 60 seconds.
  • If the target is missed, the intruders win instantly.
Reactor rule

Put the laptop in a different room from the meeting area. If the reactor is right beside the meeting area, the mechanic loses most of its tension.

Intruder Cards

You do not need to memorize every card to start playing.

Just understand the kinds of pressure intruders can create. The exact deck can vary based on your settings and whether reactor or speakers are enabled.

Fake tasks

Intruders can send a crewmate on a fake errand. Fake tasks waste time and do not add to the crew's score.

Meetings and misdirection

Cards like Self Report let intruders create a meeting on their own and redirect suspicion after a kill.

Space control

EMP and area denial cards can interfere with devices or temporarily make a location unusable.

Reactor pressure

Some cards start meltdowns or shorten the time crews have to solve them, which makes late-game chaos much worse.

Late game gets sharper

Intruders start with cards and can draw more after meetings, so surviving intruders become more dangerous over time.

Winning

This is the part new players misread most often.

Tasks matter, but they do not finish the match by themselves. Voting is still what ends the game.

Crew wins by removing every intruder

  • If all intruders are voted out, the crew wins immediately.
  • If the task meter reaches 100%, the game reveals the intruders by name.
  • That reveal is powerful, but it does not end the game on its own. The crew still has to get the intruders voted out.

Intruders win by numbers or meltdown

  • Intruders win when the number of living crewmates is equal to or lower than the number of living intruders.
  • Intruders also win if meltdown succeeds.
  • Example: if 2 intruders are alive and only 2 crewmates remain, the intruders have already won.

Host Script

Use this as the 30-second briefing before game start.

If you only say a few things out loud, say these.

What every player needs to hear

  • Your phone gives you instructions, but the game happens in the house.
  • Crewmates do tasks and try to vote out every intruder.
  • Intruders fake tasks, kill quietly, and try to survive meetings.
  • If you die, stay quiet and wait. The "I'm Dead" button only appears on your phone during a meeting — press it then so the game knows.

The two reminders people forget

  • No talking when a meeting is called until everyone is back and ready.
  • Finishing all tasks reveals the intruders, but the crew still needs them voted out to finish the game.

Ready to Host?

Open the game, create a room, build a task list, and walk everyone through the host script once before you start.
