Send me any lesson — a topic, a worksheet, or just ‘fractions, grade 4’ — and within 24 hours you get a custom interactive game built for your class, hosted at its own link on playbops.com. No installs, no student accounts: share one link or project the QR code. Works on any device in the browser. Includes one revision round. Full refund within 14 days if your class doesn’t love it.
