When battling the Power, don't flip indiscriminately. This leads the ball to the middle and down the lower hole. Instead try to flip when the ball is below the black circles in an attempt to pull the ball upward and hopefully through the top hole. If the ball instead comes down the middle, grab it with one magnet, not both, as activating both magnets will cancel each other out. A gentle style works best. Also, keep flipping after the timer reaches 0, you have another few seconds before the magnets truly go dead, and defeating the Power during this time generally still counts.
