Host a Lobby
Run a live game for friends or a whole class. You get a code, everyone joins on their own device, and you all play the same game together.
Teachers: run a live game for your class from your class page. Students join from Classes on their own devices and you see their scores live. Classic Battle lobbies are real: up to 40 players, each on their own device (they need an account). Other modes are a demo that only runs in one browser.
