An accessible pinball machine, often with the coin door open or removed, allows for unobstructed access to the playfield and internal mechanisms. This setup is commonly used for maintenance, repair, game development, and competitive play, providing the ability to directly manipulate the ball and other components. For instance, technicians might utilize this access to diagnose malfunctions, while tournament players could practice specific shots.
This open access provides a significant advantage in understanding the intricate workings of these machines. It allows for detailed study of the interplay between mechanics, electronics, and software that contribute to the gameplay experience. Historically, this type of access was crucial for developing new game features and refining existing ones. Furthermore, it fosters a deeper appreciation for the engineering and artistry involved in pinball machine design. Modern competitive pinball often benefits from this level of access, facilitating advanced techniques and strategies.
