What it does

The short version

  • Five different games in one, for up to twelve people in the same room.
  • Available in seven languages, chosen per game.
  • Built so nobody can peek at the answers early, even if they go looking.
  • Free to play, with an optional paid tier for bigger rooms and longer games.

Built with

The tools underneath. You do not need to know what any of these are; they are here for anyone who does.
