Engineer: Cars is a puzzle game based on the concept of perspective and optical illusion. The object is to assemble a series of different-sized pieces, so that they form a full-size model of a car, such as a Ferrari 360 Spider, a Honda Civic Type R, or a Toyota RAV4. The pieces are arranged on the screen in a manner that makes it seem as though the model is in front of you, even when it is not.

This puzzle game is based on the concept of perspective, which means that the distance between the object and the camera is proportional to the size of the object. For instance, if the object is close to you, the image will appear to be small, and if it is far from you, the image will appear to be large. This makes it possible to challenge yourself, by assembling the pieces in order to form a larger-sized object. It is also possible to challenge your friends, by creating a game with them and see who is the best at assembling the pieces.
