Marble race simulator FAQ

How does the marble race simulator work?

Each marble is a physics body with gravity, bounce and friction. They start behind a gate, roll and collide down the track, and the first to cross the finish line wins.

Can I replay a race?

Yes. Every race has a seed: the same racers, track and seed always run the same race, so you can replay it or export it again in another format.

How long is a race?

Usually 15 to 60 seconds, depending on the track and the number of marbles. You can end the race when the winner or the top three finish.

Can I make a marble race video?

Yes. Export the race with countdown, leaderboard, results and synthesized sound as an MP4 in 9:16, 1:1 or 16:9, free and without a watermark.

Is the marble race simulator free?

Yes. No sign-up and no limits. It runs in your browser.
