A training game ball is described having cues for visually indicating the rotational alignment of the ball when it is thrown. If the ball is improperly thrown so that the axis of rotation does not stay perpendicular to the direction of flight, then the rotational alignment cue line will appear to wobble as the ball travels. The ball also has a rotational speed cue formed from a plurality of spaced panels arranged parallel with the alignment cue. If the ball is thrown with a high rotational speed, the panels will appear to the player as a solid line. Still further, the ball also includes hand alignment cues for assisting a player in properly positioning his or her hands for throwing the ball. Each of the cues may have a different appearance, so that they may be visually distinguished.
