Rule 1: The game involves a ball (usually a basketball, rarely a tennis ball), a backboard, a hoop, and inner/outer fields. Your goal is to get the ball through the hoop or at least cross its middle.
Rule 2: Drag in the opposite direction of where you want to shoot to aim.
Rule 3: The longer the drag, the more powerful your shot. Aim for the backboard or directly at the hoop.
Rule 4: Each successful shot increases your score by 1 and spawns a new level. The inner field rotates, changing the direction the ball falls.
Rule 5: Avoid falling out of the map, as this will result in a game loss.
