Abstract: A basketball having a generally spherical exterior surface with a plurality of spaced apart grippable apertures disposed entirely around the exterior surface. The apertures define a convex surface therebetween. Each of the apertures are sized and configured to releaseably receive a portion of a fingertip or thumb tip of one of a hand. The depth and width of the apertures are selected to provide a firm grip, yet allow quick and easy release of the basketball as required for the successful execution of a one-handed dunk. The size and shape of the convex surface is selected to facilitate normal surface contact, thereby allowing the basketball to be dribbled, passed and shot as a standard basketball. Spacing of the apertures and convex surfaces allow players with varying finger spans and grip strength to securely guide the basketball with one hand through the rim of a basket while executing a one-handed dunk.
