-Pink: frame with with four black wheels.
-Brown: engine, turn the yellow key to start.
-Blue: a gear contraption with thee connected gears.
-Green: a gear contraption with an idle through-axle.
-Purple: a non-symmetrical gear contraption.
-Gold: a gear contraption with a through-axle connected to two gears.
The gears and axles have been color coded for easier identification of its function. The yellow gears connect to the outside. The white parts are through-axles. The cyan gears rotate freely around an exle. The red axles are blocked and cannot rotate at all.

For each challenge, you set up a set of gear contraptions. The object is to add, remove, turn or move gear contraptions such that the wheels spin in the forward direction when the engine key is turned. The challenges are front wheel drive, rear-wheel drive or four-wheel drive (hardest). The challenges are still under development.
