This is a fingertip ball designed to teach you to bowl like the professionals. Insert your fingers in the holes as far as the first knuckle. Your fingers should be snug in the holes, not loose.  The EZBowler™ has two sets of finger holes - one set for larger fingers and a smaller set for smaller fingers.

When gripping the EZBowler properly, your little finger should be on the outside edge of the ball. Your thumb should be toward the center of the ball.

The larger finger holes rotate to improve how the EZBowler sits on your hand. The middle finger and the ring finger are often different lengths. By rotating the holes you can adjust the lines on the ball so they are square with your arm during the swing.

The ball is light enough that thumb holes are not necessary; however, if you feel you need a thumb hole, your local pro shop should be able to create one for you.
