The objective of the game is given as it is in the name of the game, which is parking car. All you need to do is to park your car at the designated area in the parking lot. Sure, it sounds easy to do, but trust me on this as you will need a skill to park your car correctly.
Parking a car means not hitting any other car on the parking lot or you will be in big trouble. Aside from getting in trouble yourself, your car will also be damage and that is something you might not want to happen.
