📺 Hosting a livestream quiz

With QuizWitz Live, it’s easy to host a fully interactive livestream quiz on platforms like Twitch, YouTube Live, or Facebook Live — even for large audiences. This guide walks you through setup, delay handling, and presentation best practices.

🧭 If you're new to the Quizmaster app, start with the Quizmaster startup guide.

🎤 The quizmaster setup​

The quizmaster is the heart of your event. They control the pacing, present the questions, and keep your audience engaged.

Use the Quizmaster app to run the game. Launch QuizWitz Live from the quiz editor by clicking Start QuizWitz Live.

💡 The Quizmaster app is a web app — there’s no installation. Just go to quizwitz.tv on your presentation device and enter the Master Code.

We recommend using a tablet or smartphone so the quizmaster can move freely during the show.

🧩 Choosing the right game mode​

When starting QuizWitz Live, you’ll be asked to choose a mode:

  • Regular mode — Players or teams each receive a unique code. Useful for pre-registered team events.
  • Ad-hoc mode — One shared Game Code for all players. Best for livestreams with open registration.

For livestreams, always choose Ad-hoc mode and click Start ad-hoc game.

Once the quiz loads, the Quizmaster app will display:

  • Master Code — for the quizmaster
  • Jury Code — for reviewing open questions
  • Regie Code — for controlling visuals/audio
  • Game Code — for players to join

Your game screen now shows the Connect screen, which is what you should stream to your audience.

🎥 Streaming to Twitch (or others)​

To stream your quiz, use broadcasting software. We recommend:

  • OBS Studio (Open Broadcast Software) — free and powerful
  • Alternatives: Streamlabs, vMix, or native options for Zoom/Meet

If you're using meeting software like Zoom or Google Meet:

  • Simply share your screen
  • Press Start in the Quizmaster app
  • Players can participate in near real time

For Twitch, YouTube Live, or Facebook Live, you’ll experience a streaming delay (aka transcoding delay).

✅ We recommend Twitch for best results — it consistently offers low-latency performance and good viewer sync.

⏱️ Setting the QuizWitz player delay​

To compensate for stream delay, use the player interaction delay in the Jury app.

Here’s how:

  1. Start your stream preview — no need to go live yet
  2. Open the Jury app by entering your Jury Code at catlab.tv
  3. Go to Game control
  4. Open your livestream in another window, with sound
  5. Use a stopwatch
  6. In the Jury app, hit the Buzzer button and start timing
  7. When you hear the buzzer on the livestream, stop the stopwatch
  8. Round up the delay (in seconds) and enter it in the Player interaction delay field
  9. Click Confirm setting

🎯 It’s better to slightly overestimate the delay. This ensures players see the answer options only after you’ve finished reading the question.

🚀 Going live​

Once the delay is set and your players are connected:

  • Start your Twitch stream
  • Use the Quizmaster app to launch the quiz
  • QuizWitz will handle timing in the background — no need to pause between questions

💡 Livestream presentation tips​

  • Do not let the quizmaster watch the delayed stream — they should use only the live Quizmaster app to avoid awkward pauses.

  • To interact with the audience, monitor live comments on a separate screen — not the video feed.

  • Want to switch OBS scenes automatically? Use:

  • Want to trigger MIDI devices during the game? Try:

  • Looking for more tools? Visit regie.catlab.eu — a central hub with additional utilities for automation, scene switching, effects, and more.

All tools require your Regie Code from the Quizmaster app.

You're ready to go live! Twitch offers a smooth, responsive platform for hosting large-scale quiz events. Combine that with QuizWitz Live — and your quiz night is set to impress.
