Mario Kart Tour continues the traditions of the series - during races, you can find question marks that give you bonuses. You can use them to gain advantage in that race. This page of the guide lists all the items available in the game.
During the race, you will regularly encounter question marks located on the track. When you drive through them, you will receive one out of the three available items. Their number depends on the character, as well as the track. At some point in the game, you will get access to vouchers that allow you to re-draw items after driving through a question mark.
