Abstract: Systems and methods for deploying components within pinball machines. In some embodiments, a device may include a physical object coupled to an actuator via a flexible link, the physical object configured to interact with a pinball within a playfield of a pinball machine under control of the actuator. In other embodiments, a pinball machine may include a physical object configured to directly or indirectly interact with a pinball during a pinball game, the physical object coupled to an area within a playfield of the pinball machine other than a playable surface accessible to the pinball during a pinball game, the physical object suspended above the playable surface. In yet other embodiments, a pinball machine may include a plastic playfield cover configured to cover a playfield of the pinball machine, the plastic playfield cover configured to provide a player with access to one or more physical objects within the playfield.

Abstract: Pinball machines with modular components. In some cases, a method may include providing a cabinet having a first lateral portion and a second lateral portion; and assembling a pinball machine, at least in part, by sliding a physical object into or onto: (a) a support element of the first lateral portion, and (b) a support element of the second lateral portion. A pinball machine may include a cabinet having a first lateral portion and a second lateral portion, and a user-replaceable module coupled to an outside surface of the first or second lateral portions, where the user-replaceable module includes one or more controls or terminals configured to communicate with the machine via an interface. Moreover, the pinball machine may also include a user-replaceable magnetic decal coupled to a metallic outside surface of the first or second lateral portions.

Abstract: Pinball machines with controllable lighting components. In some embodiments, a method may include electronically determining a physical property of a ball, the ball configured to move within a playfield of a pinball machine during a pinball game, and modifying a characteristic of a light emitted by a pinball target in response to an evaluation of the physical property. In other embodiments, a pinball machine may be configured to identify a state or mode of a game, and to control a light emitted by a pinball target located within the playfield in response to the state or mode, thus providing a visual indication of the state or mode. In yet other embodiments, a pinball target may include a substrate configured to receive impact from a ball during a game and a light element embedded within the substrate, the light element configurable to emit a light having a controllable property.
