Party game · 4–20 players

Everyone gets the same word. Almost.

Halfword is a pass-and-play party game for one room, based on the word game Undercover. Most of the table shares a secret word, a few players get a nearby one, and sometimes one gets nothing at all. Describe yours without saying it, then vote out whoever sounds off.

One phone is enough. No account, no internet.

How a round works

First the deal: the phone goes round, and each player sees their word in secret. Then the table plays round after round until one side wins.

  1. Describe

    One clue each, in turn. Never the word itself. Too vague looks suspicious, too exact gives it away.

  2. Discuss

    Whose clue didn’t fit? Talk it over. Nobody says their word.

  3. Vote

    Then everyone votes: in secret as the phone goes round, or on three by pointing. The phone counts every vote, or the host just taps who got the most. A tie gets one more clue from each tied player, then a new vote.

  4. Out

    The player with the most votes is out, and the phone shows what they were.

Caught Mr. White? They get one guess at the Civilians’ word. If it’s right, they steal the win.

How it ends

  • Five cyan circles, the Civilians, huddled together under a burst of light

    The table wins when every Undercover and Mr. White is out.

  • A giant rose triangle and Mr. White’s empty square next to the smug Half, with the last Civilian cornered

    The hunted win once as many of them are still in as the Civilians.

  • Mr. White’s empty square, saying the whole word in a speech bubble

    Mr. White wins on the spot by naming the Civilians’ word after being caught.

Three roles, three shapes

Your card shows only your word: Civilians and Undercovers aren’t told which they are. Only Mr. White knows his role. And colour is never the only clue: every role has its own shape.

  • The Civilians’ shape, shown when one is out: one big cyan circle among many small ones

    Civilian

    Circle, cyan

    Gets the word most of the table shares. Wins by finding everyone who doesn’t have it.

  • The Undercovers’ shape, shown when one is out: a tilted rose triangle hiding among rose dots

    Undercover

    Triangle, rose

    Gets a nearby word, tea while everyone else has coffee, and isn’t told it’s different. Wins by blending in.

  • The Mr. White card: an empty square on a dark card

    Mr. White

    Hollow square, paper

    Gets no word at all. Listens, bluffs, and if caught, gets one guess at the Civilians’ word.

The app suggests how many Undercovers and Mr. Whites suit your group, and you can change it, play without Mr. White, or put the Undercovers on the table’s side.

Eight special roles

Optional twists. Switch on any mix: six go to players on top of their role, and the Ghost and Mr. Meme change the rules for the whole table.

  • Goddess of Justice

    Breaks every tie, even after she’s out.

One phone, or everyone’s own

Play on one phone today. Later, everyone at the table will be able to use their own.

Now

Pass and play

One phone goes round the table, and the whole game runs on it.

  • Each player looks at their word alone, then passes the phone on.
  • No Wi-Fi, no mobile data, no account.
  • Scores add up over every game of the evening.

Coming later

Everyone’s own phone

One phone or tablet hosts the table. If a player’s phone drops out, they use the host’s screen and the game goes on.

  • Join by scanning the host’s QR code.
  • Phones on the same Wi-Fi talk to each other directly.
  • The rest go through an encrypted relay that can’t read a word.

Words written for each language

Word packs in English, German, Spanish, Russian, Belarusian and Ukrainian, each written on its own and never translated. Pairs rarely survive translation: clock and watch make a fine English pair, but German has Uhr for both.

Pick a difficulty from 1 to 5, and pairs your table played lately are skipped. The app itself comes in all six languages, and its language and the word language are set separately.

Close enough to share clues, different enough to slip.

What happens at the table stays there

No account. Names, words and scores stay on your phones. Game statistics are off unless you turn them on, and even then they carry no names, nothing anyone typed and no device ID.
