One free roll is awarded every five hours. Advance the time on your device by that amount, collect your gift, then repeat the process as many times as desired. Afterwards, set the time back to its correct value. You can only get new cars of any rank by rerolling until you get lucky. If you are just starting the game you can roll and then uninstall the game, reinstall, then try again until you get a rare car. Collect coins by racing to spend on rolls. Note: With luck you may get the Money Man Truck as a legendary car. It rewards you with five times the cash prize from races. After dying several times, you will be given the opportunity to watch a video advertisement to earn at least 20 coins. There is a daily limit to the number of ads you can view.
