Quantum computing you can play, build & learn — nothing to install.
Quantum games, LEGO and 3D-printed quantum computer models, and hands-on ways to learn. Open source, workshop-tested, built by the RasQberry community.
Play →
Build circuits with your hands, order coffee with a circuit, steer a runner with quantum gates — and try to beat a quantum computer at coin flipping.
Learn →
Take the official courses, keep coding in ready-made environments, prepare for the Qiskit certification, run real Qiskit code in your browser — and build your own quantum games.
🪙 Quantum Coin Game →
A gentle first look at superposition and interference — play it right in your browser, no account needed.
🧸 Qutie →
Palm-sized quantum computer models, 3D-printable in one piece. No electronics, no assembly — quantum for your desk.
🎓 CertiQ →
Get ready for the IBM Qiskit developer certification — guided path, drills, and a 68-question mock exam. Every question with code is checked by running it.
Play Quantum Runner
Steer the runner with quantum gates — an H gate puts you in both lanes at once.
Spin the model
Quantego Two, a LEGO model of IBM Quantum System Two — drag to spin it in 3D.
Launch a notebook from GitHub
Paste a link to a GitHub repository or notebook and run it in one click — Qiskit comes preinstalled.

One family, one idea: quantum computing is more fun hands-on
Fun with Quantum is the front door to a family of open-source quantum outreach projects that grew over years of talks, workshops, and conference booths: quantum games you play in the browser, quantum computer models you 3D-print or build from LEGO, and hands-on ways to learn and teach. Everything is open source and tested on real audiences, from school classes to IEEE conferences, and most of it runs without accounts or installs.
The family is built by Jan-R. Lahmann and the RasQberry community. Contributions are welcome in every repository — start at github.com/JanLahmann.
Running a workshop or event? We help you prepare it, free, as part of our open-source community work.
