Current public information points players toward solo play, local multiplayer for up to four players, and Twitch-facing modes. Do not expect official online lobbies or a browser-play version.
The word online mixes several player intents. Keep them separate before planning a session.
The official listing does not present internet lobbies. Build plans around local play or streaming features.
The game-show format supports local sessions, so the safest expectation is players sharing the same setup.
Streamer-focused modes and Twitch voting/chatter features are closer to remote participation than normal online multiplayer.
Players may experiment with Discord audio routing, but that is a workaround topic, not an official online mode.
Pages advertising play-without-download should be treated as separate websites unless they link clearly to official sources.
Remote-session experiments can expose recording, playback, and virtual device issues faster than local play.
Short answers for online and multiplayer searches.
Start with the gameplay guide for modes, then use troubleshooting if Discord, virtual audio, or playback creates problems.
