In Flag Rally, the more flags you turn in at once will give you a stacked bonus of points. For this reason, be mindful of how many flags you carry with you as you go to turn them in. Four flags will be all it takes to complete the match, and any less will make it more difficult. Playing on Easy, they will try to always turn in a flag if they acquire one, so you could always pick up a Vacuum power up, wait near the point, and suck it out of them. Acquire three flags (noted by three pennants flying behind your driver) and run into the goal to bank them, then repeat another time.
