Abstract
An electronic alphanumeric indicator is disposed at a target location on the playfield of a pinball machine. The electronic alphanumeric indicator, for example, is disposed just above and behind the target, or in the top portion of the target. For a drop target, the target is transparent and the electronic alphanumeric indicator is mounted on the back side of the target. The electronic alphanumeric indicator, for example, indicates the number of points associated with the target, or the time remaining for the player to complete a task on the playfield.
