Are Viafocus lessons free?

Yes — every lesson in the library is free to play in the browser, with no account required. A free account lets you save lessons and see results.

Can I run a lesson live with my class?

Yes. Start a live session from any lesson — students join with a code on their own devices, and their answers land on your dashboard in real time.

Who creates the lessons?

Teachers in the community and the Viafocus studio team. Lessons built by the Viafocus studio carry a blue verified mark next to the byline.

Can I use a lesson someone else made?

Yes. Any published lesson can be played, shared with a class, or copied into your own library so you can adapt it before teaching it.

The Jam That Came Back

A queue on the ring road with no accident, no roadworks and no cause. Drive one car in a circle of fourteen, tap the brake once, and watch what you made travel backwards through everyone behind you until, a minute later, it arrives at your own bumper.
