One Shared Word: Word Game Rules

One Shared Word game cover

2–12 players

Free, with no login or installation. Each player needs their own phone or computer and an internet connection. Share the room link or six-character code privately. New players can join only in the lobby.

Rules

  1. The game chooses a topic and a random turn order.
  2. On your turn, add a condition or association (80 characters), or choose “Ready to answer.” Add clues gradually rather than writing the answer itself.
  3. The host selects typed or spoken answers. Typed answers (40 characters) stay hidden until everyone submits and cannot be changed afterward.
  4. For spoken answers, say them together on the host’s count. Audio is never recorded or sent.
  5. Discuss whether the answers match, including different spellings. The host confirms a match or no match. Either result ends the attempt. Play again with a new topic or return to the lobby.

A cooperative word game

Imagine the topic is food. One player adds “something sweet,” then another adds “served cold.” When you are ready, everyone answers. “Ice cream” and “sorbet” are different answers: discuss the result and let the host confirm whether the group matched.

Play together, nearby or online

Each friend joins the same room on their own phone or computer. If you are apart, use your usual voice or video call for discussion; the game does not provide a voice call. Try the solo demo first to learn the controls, then create a room in English and share its invitation link.

Language and privacy

The room language is fixed at creation and applies to every player. Create a new room to change it. Your own text is never automatically translated. Use the general guide for room setup and reconnecting.
