In Sim Taxi, you have to carry your customers to where they want to go. What a beautiful job, isn't it?
You have to be quick and CAREFUL. Transport them as fast as you can but do not involve any trafic accident. Unless you don't have to pay extra money and repair your car. If your car's gas is about to running out, find and visit the gas station immediately. Controls are very similar to GTA 2's gameplay. Use Up Arrow key to accelerate and press Left/Right Arrow keys to turn your car left / right. If you want to repair your car and buy gas use "Space" on relevant spots.
