Taxi Simulator is different from normal taxi driving simulation games because of more modes and steps. In the Work Mode, you can accept customers' orders and transport them to the destinations at each level. When you earn some cash, you can unlock another 9 vehicles in the garage. After you complete some levels, you can unlock more maps in the Free Mode. Follow the blue arrow and pass the checkpoints while driving, refuel in the gas station when you are out of gas.
