Addictive; dont waste your diamonds

I started playing this with my 4 year old but it soon became my addiction. Im now at a point where I want to start over but cant. I wish I never wasted my diamonds on fuel and saved up for cars. Watching an ad doesnt always give you fuel. Great game but it needs more guidelines and definitions like what a kickback is.

need something to keep busy about Crazy Taxi City Rush, v1.6.4
