Imposter Game Ideas for Large Groups

Updated 14 October 2026

The imposter game is at its best when the room is full. More players means more clues, more suspects and more chaos when the vote comes in. But a group of 15 can also drag if nobody manages the pace. These imposter game ideas for large groups will help you keep a 10 to 20 person game moving, whether you are at a family gathering, a classroom, an office party or a big birthday.

Use more than one imposter

With one imposter among 15 players, the imposter is barely involved and the civilians have an easy time spotting the odd clue. Imposter Game recommends the imposter count automatically:

You can adjust it. If your group is experienced, try one more imposter than recommended. If it is a younger or newer crowd, stick with the default.

Multiple imposters change the feel of the game. In Undercover mode, all imposters get the same imposter word, so two imposters may hear each other's clues and think "at least someone agrees with me". That false sense of safety is a big part of the fun. Each round still has one vote: if an imposter is caught, the civilians score, but any imposter who stayed hidden still scores 2 points for surviving.

Keep the pace up

Use Quick Play and rename later

Typing 18 names before the first round kills the mood. Quick Play starts a game in two taps: pick the number of players and tap start. Players are named Player 1 to Player 18, and you can rename them as you go.

Turn on the timer

With many players, discussion can spiral. The optional timer (1, 2, 3 or 5 minutes) gives the debate a clear end. For 10 to 15 players, 2 or 3 minutes usually feels right.

One clue, short and sharp

Ask for one word or a short phrase. With 20 players, even 10 seconds per clue adds up to several minutes. Imposter Game shows a random first speaker and speaking order, so nobody argues about who goes next.

Choose broad, well-known packs

In a big mixed group, not everyone knows Bollywood or cricket. Food, Animals, Household Objects and Family Night work for almost everyone. "Random mix" keeps things varied. Browse all packs on the imposter game words page.

Voting with a crowd

Pass-the-phone mode has two voting styles:

• Group vote: the group discusses, agrees on a suspect and taps once. Fast, and good for big rooms where people point and shout anyway.
• Secret vote: the phone is passed again and each player votes privately. Slower with 20 people, but it stops loud players from steering the result and gives imposters a fairer chance.

A practical approach is to use group votes for most rounds and a secret vote for the final round of the night. Big rooms often split between two suspects or vote out an innocent player. That is where Keep playing after a wrong vote shines: the imposter stays secret, the voted-out player sits out, and the host can run another clue round instead of ending the game. With 8 or more players, the group gets several tries before the imposters can take over.

Split into tables, or go online

Splitting into tables

Pass-the-phone mode supports up to 20 players, but passing one phone round 20 people takes time. If you have two phones, split into two tables of 8 to 10. Each table runs its own game, and you can compare scoreboards at the end, or swap a few players between tables every few rounds to mix things up. Since the game runs in the browser, the second phone just needs to open the same link.

Online rooms for up to 15

If everyone has their own phone, an online room removes the passing entirely. The host creates a room and shares a 6-character code, an invite link or a QR code (great to put on a screen at the front of a room). Up to 15 players can join, everyone sees their word on their own phone, and everyone votes on their own phone. If someone's page refreshes, they rejoin the same seat. Online rooms need internet; pass-the-phone mode works offline after the first visit. Read more on imposter game online.

Big-screen mode

Playing in a living room or a classroom? Big-screen mode is designed for showing the game on a TV, so the whole room can follow along. Teachers will find more ideas on the classroom page, and team leads on the office page.

House rules that work well with big groups

• Two clue rounds for 15 or more. A second lap gives civilians more evidence and makes imposters work harder.
• No repeated clues. With 20 people, repeats creep in. Ban exact repeats and obvious synonyms.
• The accuser explains. Before the vote, anyone who wants to accuse someone gets one sentence to explain why. It keeps discussion focused.
• Loser adds a pair. Turn on the optional rule (off by default) where the loser adds a new word pair. Big groups produce some brilliant custom pairs, and you can share your custom pack with friends as a link afterwards.
• Strict mode for competitive groups. With so many hands on one phone, turn on Strict mode so each player sets a personal PIN before seeing their word.
• Last chance on. Keep the Last chance rule enabled. When an imposter is caught, the whole room goes quiet for their guess, and a correct one steals the win.

A sample game plan for 16 players

1. Open the game, choose Quick Play with 16 players. The game suggests 3 imposters.
2. Pick Food and Animals for the first rounds. Leave the timer on 3 minutes.
3. Play three rounds with group votes. Use "Play again" to deal a new pair instantly to the same players.
4. Switch to Movies or a themed pack once everyone knows the flow.
5. Finish with a secret-vote round and check the scoreboard. Civilians earn 1 point each per catch, imposters 2 for surviving and 1 for a correct last-chance guess.

A sample round: civilians have "Lion", imposters have "Tiger". Clues come in: "mane", "Africa", "pride", "king", "stripes". That last clue should get a lot of attention. But with three imposters, the others may have said safe clues like "big cat" or "zoo", and they can still slip through.
