Wacky Challenge is a historic car-racing competition where the world's greatest scientists build and race their own invention-automobile.
The race represents 7-days racing within 24-hours around the world. The game consists of completing the 7 sets of races with multiple tracks each. Each track consists of playing through the traps set by all players among them.

Although all cars compete at the same time, there are separate classes and features. Any kind of mechanical feature is being permitted. The racing competition is won by the car that covers the greatest distance within the 7 days. Racing cars must balance the demands of speed with the vehicle' ability to function for 24 hours without mechanical failure.
