TCB Companion

About

TCB Companion is the official side-panel companion for Tokyo Cam Bingo (TCB). Keep your game docked next to whatever you're doing, get a nudge the moment it's your turn or someone shouts BINGO, and jump back into any room with a single click — no account required.

Click the toolbar icon and the side panel opens instantly (there's no popup to fuss with). Paste a room code and you're in.

What it does

🎮 One code, instant connect — Paste any room code and the panel figures out the rest: it knows whether you're a player or a spectator, and whether you're the host. Works across every TCB mode: Bingo, Tournaments, Scoreboard, Bro vs Bro, and Mini-Games.

🔔 Live desktop notifications — Never miss the moment, even when TCB isn't your active tab:

🎯 "It's your turn" — fires only when the turn actually swings to you
⏱️ "Time's up" — when the round timer expires
🎉 "Bingo!" / "You won!" — with the winning condition
🏆 "Tournament finished" — with the winner
🏁 "Game finished" — so you always know when a match wraps
🎛️ Host control deck — Run the room without switching tabs. Your host controls live right in the docked panel.

⚡ One-click quick-resume — Your recent rooms are remembered locally, so hopping back into a game (or reconnecting after a drop) is a single tap.

📌 Always-on side panel — Dock it beside your work, stream, or chat. It stays put and stays live.

Built to be lightweight & private

No account needed. TCB uses a simple code + PIN model — there's nothing to sign up for.
Anonymous by design. The extension reports only a random, rotating ID for basic usage counts. It never collects personal data.
No video, ever. Despite the name, TCB Companion is about the games — it never embeds or accesses any camera or video feed.
Minimal footprint. A focused side panel and a background connection — that's it.
Permissions, briefly

Notifications — to deliver the turn/win/finish alerts above.
Side panel — the entire UI lives here.
Storage — to remember your recent rooms for quick-resume.
Clipboard (read) — so you can paste a room code in one tap.
Site access (tcb.wtf) — to connect to your TCB games in real time.
