Can I use my own questions?

Yes — add them one at a time, paste a whole list in the Import tab, or import a JSON file you exported earlier. You can also load a built-in template to start fast.

How long can the timer be?

Pick 5, 10, 15, 30, or 60 seconds, or type any custom length. You can pause, resume, and restart the countdown during a question.

Yes. Marking a question correct awards points to the team whose turn it is (more for harder questions), and you can adjust any score by hand. The leader gets a crown.

Is it free and private?

Completely free with no ads. Questions and scores are stored only in your browser via localStorage — nothing is sent to a server.
