发明名称 Drop gaming machine with varying symbol scoring zones and automatic bias prevention
摘要 A game machine which includes a playing field traversed by objects, such as balls or other traversing bodies. A preferred form includes a playing field with a maze, such as of deflectors, and plural drop zones which can be selected by the player that control where the balls are launched. Detectors indicate scoring positions assumed by the balls or other traversing objects. A payline display may be included to display scored events. A symbol selector is included to select symbols which are variably assigned to the scoring positions. To eliminate possible bias due to wear and other causes the detectors are assigned individual symbols in a manner that produces equal frequencies of appearance in each of the detection positions. Scored symbols may be displayed in one or more payline displays and affect winning or bonus play.
