Step into a neon 3D karaoke (KTV) private room with friends!

How to play

• Join a room: enter the public lounge, or type a code to open a private room for up to 8 people.
• Chat: press Enter to type; messages appear in the chat log and above your avatar.
• Sing: paste a YouTube / Bilibili video link or BV id right in the song menu, or search by keyword; add to the queue, insert as next song, play now or skip, all synced for the whole room. Press "📺 Cast to big screen" to show the video on the room's big screen.
• Shared web: a separate shared-web panel opens google.com by default; enter a URL and everyone in the room browses the same page; it can also be cast to the big screen.
• Live screen + audio share: press "📡 Live share screen + audio" and share a browser tab; everyone in the room sees your actions live and hears the page's sound; turn on "🖱️ Co-control" and everyone's cursor, clicks, scrolling and typed text appear on the shared screen for the whole room.
• Synced back / forward / reload: the shared-web history is shared by the room; anyone can press them and it syncs for everybody.
• Voice & mic controls: turn on your mic and everyone in the room hears you (if a direct link fails, voice is relayed through the server automatically); adjust chat, singer, music and your own mic volume separately, with ear monitoring, reverb and key (pitch) up/down.
• One menu everywhere: web mode and VR share the same tabbed menu (🎵 Songs, 📋 Queue, 🌐 Web, 🎙️ Mic, 💬 Chat/More); open or close it with the top-right "☰ Menu" button or the M key, and press Enter to chat.
• VR big-screen video: in VR the YouTube song video plays in sync on the room's big screen (Bilibili plays audio only in VR).
• VR: WebXR headsets such as Meta Quest 2 can enter VR mode with the "🥽 Enter VR" button at the bottom right after joining a room; press the controller ☰ menu button or B / Y to open a floating menu, point and pull the trigger to search songs, manage the queue, open web pages, adjust the mic and chat; left stick moves, right stick turns.

Controls: WASD / arrow keys to move, drag the mouse to look, press 👏 to cheer the singer.

The interface is in Traditional Chinese.
