FeynLab: the free advanced-physics game built on Feynman diagrams
FeynLab is our most advanced game, built for teens and enthusiasts who want the real thing. Learners read and assemble Feynman diagrams, work through fundamental interactions and conservation laws, and explore the Higgs and the exotic particle zoo. It's free, with no ads and no tracking of your kids.
What kids learn
- The visual grammar of Feynman diagrams: fermion, photon, gluon, weak, and Higgs lines
- How forces act by exchanging virtual carrier particles
- Quark content and charge of hadrons like the proton, pion, and omega
- Testing reactions against conservation of charge, lepton number, and baryon number
- Spin and statistics: fermions and the Pauli exclusion principle versus bosons
- The Higgs field and discovery — with hypotheses like supersymmetry clearly flagged as unconfirmed
How it works
FeynLab is a multiple-choice quiz built around a real Feynman-diagram renderer. Some questions ask you to read a diagram; a build mode has you fill each labeled slot with the correct particle or line; and conservation levels have you audit charge, lepton, and baryon ledgers to rule a reaction allowed or forbidden. Difficulty ramps within each run, and stars reflect accuracy.
A grown-up signs in once and adds a player for each kid, so FeynLab's stars and progress save to your account and follow you to any device.
