In this game you are working in a car workshop. Cars will arrive. The first thing you need to do is to place the car you're going to work on in the working area. Click on the car and then on the working area to do so. Each car will have a bubble above it. The picture in the bubble represents the service this car needs. It can be refueling, changing tires or mechanical works. Click on the corresponding area on the screen, wait until your character walks there and takes the needed object. Then click on the car to provide the service. Do it before the car's timer runs out or you'll lose a customer.
