Yes, of course!
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. We even buy unused cards back at the end of the race! 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!
