A flipper drain device of a pinball machine is provided, including a fixed rack and a drain and ball-striking assembly. The fixed rack is mounted in the pinball machine and includes guide rods. The drain and ball-striking assembly is mounted to the guide rods, such that the drain and ball-striking assembly is leftward/rightward movable but not rotatable on the guide rods. The drain and ball-striking assembly has a drain opening and a flipper provided at each of a left part and right part thereof. The drain and ball-striking assembly includes an operation table, which is provided with an operation member. The operation member controls the drain and ball-striking assembly to selectively move leftward/rightward. The operation table is provided with an operation button on each of a left part and a right part thereof for respectively controlling the flippers of the drain and ball-striking assembly to rotate.

A software type pinball game enable players to change the background picture of the playfield and also to configure the game functional components via a drawn picture. Players can draw the picture on a paper, captures into any electronic image device, or using an electronic drawing device or application software to draw that picture into an electronic format and send to the game for conversion of game components.

A modifiable pinball machine includes a processing device, a memory storing instructions executable by the processing device, a communications interface coupled to the processing device for receiving new music data from a source external to the pinball machine for storage in the memory, and a speaker coupled to the processing device for playing music retrieved from the memory. The new music data is provided with data useable by the instructions to cause the processing device to automatically retrieve from the memory the new music data in lieu of originally provisioned music data, for playing via use of the speaker, when the pinball machine is caused to operate in a predetermined operating state.

A display signal associated with a pinball machine display is received. The display signal is interpreted. A network message is transmitted via a network interface based at least in part on the interpretation of the display signal. A network message is received via a network interface. A maintenance signal associated with the network message is submitted via a communication interface, wherein the communication interface is coupled to a pinball machine coin door panel driver board.

A rotatable ball momentum transfer assembly for an amusement gam, such as a pinball machine includes an impact ball mounted to an inclined playfield and a shaft mounted to the playfield proximate to the impact ball. A travel ball is coupled to the shaft such that the travel ball rests against the impact ball during gameplay to receive momentum from the impact ball when the impact ball is struck by a game ball, causing the travel ball to at least partially rotate about the shaft. In one example, the travel ball rotates in a fixed arc towards one of two resting positions on either side of the impact ball. These two resting positions both open or close different shot paths available during gameplay.

One or more embodiments of the invention is a program for a game executed on an electronic device that accepts player inputs, the program causing the electronic device to execute: a screen display step of displaying a game screen including a player object that moves in a game field in which a virtual gravity is set, as well as collidable objects and an operated object that are disposed in the game field; an object control step of causing the operated object to be manipulated on the basis of a player input accepted by the electronic device; and a player-object control step of giving a movement velocity to the player object in a direction toward a target object, which is one of the collidable objects, on the basis of the player input accepted by the electronic device in the case where a predetermined condition is satisfied.

The objective of the present invention is to provide a game machine employing computer simulation. This game machine is provided with a display device in a casing, and includes a game processing unit which executes a game process, and a consumption information processing unit which causes the display device to display consumption information relating to a game.

A game machine 10 includes a game board 12 and a glass unit 15 disposed in front of the game board 12. The glass unit 15 contains a luminescent material that emits visible light having a wavelength of 380 to 780 nm by excitation light.

A strategy system is described that generates a strategy guide for a gameplay session at an arcade machine. To do so, the strategy system leverages a game-specific hash generated by a hashing system, which includes data describing a log of events that occurred during the gameplay session. The strategy guide includes a summary of the gameplay session curated based on a combination of a particular user associated with the gameplay session, a rulebook describing gameplay event scoring, and the specific event sequence described in the game-specific hash. The game-specific hash and the strategy guide are configured for output based on various considerations, such as display capabilities and network connections of the computing devices implementing the strategy system and/or the hashing system as well as characteristics of a computing device at which the strategy guide is output.

A light guide plate formed from a panel transparent to visible light has a first incidence surface provided to form a sidewall of the light guide plate that faces a light source configured to emit visible light, and a plurality of prisms provided in a predetermined region on one surface of the light guide plate. The prisms include a reflection surface that reflects the visible light emitted from the light source and entering the light guide plate from the first incidence surface toward another surface of the light guide plate. The predetermined region is divided into a plurality of local regions corresponding to a plurality of tones in the predetermined region when seen from a predetermined viewpoint, and in each local region, the orientation of the reflection surface of the prisms distributed in the local region is established in accordance with the tone corresponding to that local region.
