How it works

The estimate adds both players' base time and their assumed increments, then adds breaks between rounds. It assumes all boards play simultaneously. Extra moves, reconnections, explanations and late arrivals can extend the session.

Try it with a teaching pack

Choose a pack with two starting positions. Use the scheduler to pair your students, the calculator to plan the rounds, or the worksheet to collect their ideas before play. Review one decision from each game afterward.

Put it into practice

Prepare your material for free. When you are ready to teach live, Solo brings the board, chat and video into one workspace. Students enter through your private invitation links.
