A bowling target for use in a competitive bowling game with two or more players. The face of the target is on a plane inclined at an acute angle to the horizontal surface on which the target rests, with a groove on the face of an irregular circular shape in which the ball may roll and rest. A slight ramp is placed before the front portion of the groove to deflect the ball over that portion of the groove, into the central area of the target face, where a concave recess in the center of the target face will retain a ball which barely rolls into said recess. The rear of the target is fitted with shaped protruding end walls of a concave shape. Various sections of the target face are marked with premium or penalty points.
