Drag race any two of 50,000+ real cars with physics-based simulation, tune them in a garage, compare 0–60 and quarter-mile times, and take on a new daily challenge.
Diagnose a broken engine with a virtual multimeter and wiring diagrams, the way trainee mechanics do. Scored against the clock.
Hundreds of small, clear simulations of physics, chemistry and earth science, from pendulums to tides.
A space colony game whose lab doubles as a playground of live physics simulations, from orbits to black holes and wormholes.
A gravity sandbox in the browser. Fling planets at each other, watch orbits settle or collapse, and get an intuition for the n-body problem by wrecking it.
Hundreds of physics, chemistry and biology simulations you can poke at — drag a mass onto a spring, mix a solution, build a circuit and watch it burn out.
An open-world driving game set in real cities, playable in the browser. Customise a car and cruise around with friends.
