How to play Just One

  • 1
    One player has to guess a word they cannot see; everyone else writes a single clue for it.
  • 2
    Any clue that two of you wrote is thrown away before the guesser sees anything.
  • 3
    With the clues that survive, the guesser gets one try — you all win or lose together.

Full Just One rules

The goal

  • •
    You play 13 mystery words as a team. Guess as many as possible.
  • •
    Each round one player is the guesser; everyone else writes ONE secret clue word.
  • •
    The twist: identical clues cancel each other and the guesser never sees them!

Round flow

  • •
    Everyone except the guesser sees the mystery word and writes one clue.
  • •
    Duplicate clues are cancelled automatically; the team can also cancel near-duplicates (plurals, variants) before revealing.
  • •
    The guesser sees the surviving clues and gets exactly one guess.

Clue rules

  • •
    Exactly one word. No part of the mystery word, no translations, no sound-alikes.
  • •
    Be helpful but original — obvious clues will collide and vanish.
  • •
    With 3 players, each helper writes two clues.

Scoring

  • •
    Correct guess: +1 card. Pass: the card is lost.
  • •
    Wrong guess: the card is lost AND the next card is discarded too.
  • •
    13 is perfect. 11+ is legendary. Under 4… try again!

Tips to win at Just One

  • •
    Be wary of the first clue that comes to mind: if it is the obvious one, someone else wrote it too and both get erased.
  • •
    Look for an angle nobody else will take: if the word is "beach", "sand" will surely clash; "umbrella" or "towel" have a better chance of surviving.
  • •
    If you are guessing and unsure, pass: passing only loses the card, but a wrong guess loses the next one too.
  • •
    With 3 players each helper writes two clues: make one safe and the other more original.
