After each race, you will receive coins as a reward, which are earned during the race and paid to you by your sponsors. You also have the option to double the amount of coins by watching a video, but it is not mandatory.

To keep track of your progress in the tournament, you can refer to the leaderboard. Your final score and position on the leaderboard at the end of the tournament will determine the prize you receive. The prize is based on your ranking among the participants.

Remember, the tournament leaderboard and overall score are the key factors in determining your reward, rather than specific rankings in individual races.
