Chat commands None. This one runs through the lobby code and challenge button on this page, not through Twitch chat.
Setup
  1. Streamer: add this page to OBS as a Browser Source, or just keep the tab open to accept challenges.
  2. Viewers: open this same link, enter a name, and generate or enter a lobby code to play a friend, or challenge the streamer directly.
Known problems Lobby codes expire quicker than chat tends to read them, same as tic tac toe, if a code stops working just generate a new one.
