My favourite 6 educational physics games.

• Special relativity: Velocity Raptor, a relativistic puzzle browser game

• Quantum mechanics: Quantum Game with Photons, a quantum mechanical puzzle browser game

• Newtonian mechanics: Armadillo Run, a Newtonian mechanics puzzle game

• Orbital mechanics: Orbiter, KSP, CoaDE

~Bonus~ ~games,~ ~not~ ~educational,~ ~but~ ~one~ ~can~ ~build~ ~physics~ ~intuition~ ~with~ ~them:~ ~Portal~ ~games~ ~(including~ ~the~ ~Flash~ ~version),~ ~Red~ ~Remover,~ ~Tagpro~ ~and~ ~Transformice,~ ~and~ ~honestly~ ~any~ ~realistic~ ~vehicle~ ~sim,~ ~etc...~

If you haven't played the games above I recommend you do, half are free.

What are some other cool physics games you guys know of, whether simple or in-depth, big or small, educational or not?
