You can participate in every race without purchasing anything.
We will offer you credits (our virtual currency) at the time of your registration, but also when you register for a race. You also win credits based on your ranking when you cross the finish line. Your virtual wallet can fill up on its own as you navigate and progress through the game.
If you wish, you can also purchase additional credits to fill your virtual wallet!
Please note: Certain "special" races may require the purchase of a Full Pack, such as the "Challenge the champions" events.
