Players join on their phones

When everyone is in the lobby, the host taps Start game. Questions and videos appear on the TV; players tap A, B, C or D on their phones.

Reveal and score
After each question the host reveals the correct answer. The first correct answer gets the most points; wrong answers score nothing. The live leaderboard updates on the TV after every round.

QR & room-code troubleshooting
Most setup issues are resolved in under a minute. Find your symptom below.
The room code is not found+
Room codes are only active while the host screen is open. Make sure the host has started a room and that you typed the four letters exactly as shown. The code is not case-sensitive, but it does not include the numbers 0, 1, 2, 5, 8 or the letters B, I, O, S, Z.
The QR code will not scan+
Hold the phone steady and make sure the whole QR code is visible on screen. Bright sunlight or a reflective TV can confuse the camera. If scanning fails, tap the room-code box and type the four letters manually.
A player cannot connect or keeps disconnecting+
The host and players both need an internet connection. Mobile data works fine. If one player drops, they can re-join with the same nickname and the same room code; their score is preserved for the current game.
The TV screen is too small to read+
Use a full-HD TV or projector and run the host in a modern browser. On most TVs you can press F11 on a keyboard or pinch-zoom out on a tablet to show the whole page. For the biggest text, use a laptop connected to the TV via HDMI and hide the browser toolbars.
No sound from the videos+
Check the TV volume and that the browser is not muted. Some browsers block sound until the user interacts with the page; tap the host screen once after the first video loads.
Scores are not updating on the TV+
Scores update after the host taps Reveal. If a player answered but their score did not change, check that the host screen is still on the same room and that the player joined with the correct code.
Can I run this without a smart TV?+
Yes. Any device with a browser and an HDMI output works — laptop, tablet, or desktop. Connect it to a TV or projector, open /tv, and start the room.
