Frequently asked questions

Do I need to install anything to run Build & Play simulations?▾

No. Everything runs entirely in your browser — no downloads, plugins or accounts. Works in Chrome, Firefox, Edge and Safari; most simulations also work on mobile.

Can I use these simulations for teaching?▾

Yes — all content is free for educational use under CC BY 4.0. Link to any simulation directly or embed it in your LMS with an iframe; no API key required.

Are the models scientifically accurate?▾

They use the same mathematical formulations as professional software, integrated numerically in real time. Each simulation lists its algorithms, and many link to an article explaining the mathematics.
