A structure of a solenoid of a claw includes a solenoid tube, which is provided with multiple coils that are arranged circumferentially on an outside surface at intervals. The coils have one end connected with a control switch and an opposite connected with a power supply source. A vertical tube is disposed in the solenoid tube and is provided therein with multiple magnetic elements to respectively correspond to the coils. A bottom of the vertical tube is pivotally connected to fingers of the claw. The control switch includes a chip electrically connection with multiple control elements that are connected to the coils respectively. A temperature switch is arranged on a wall of the solenoid tube to detect a temperature thereof. The temperature switch is electrically connected to the control switch. The power supply source is connected to the coils, the control switch, and the temperature switch.

A gaming machine and method include a monetary input device, a user interface configured to: enable a player to select a wager for a game of chance having a skill-based activity, to interact with the game of chance using a gaming input device. A processor is programmed to enable the player to win a prize based at least in part on input from the gaming input device, and to set at least one parameter of the skill-based activity or the gaming input device to a first difficulty for winning the prize during a first game of a gaming session including a plurality of games, and to adjust the parameter to modify the difficulty to a second difficulty for winning the prize during a subsequent game of the gaming session to maintain a predetermined percentage or percentage range of money or credits returned to the player (RTP) during the gaming session.

An arcade game permits a player to capture physical prizes using an electro-mechanical device, whereby the prizes are assigned point values, and the point values may be redeemed both to play the game and to collect awards, such as tickets.

A claw gaming machine may comprise a cabinet, a claw assembly, prize objects, and a shooter unit. The machine may be configured to: determine an outcome of a claw game; allow an input device to control the claw assembly; end the claw game when the claw assembly does not pick up a prize object and the determined outcome is a losing outcome; cause the claw assembly to move and release the picked-up object away from the shooter unit when the claw assembly does pick-up a prize object and the determined outcome is a losing outcome, cause the claw assembly to drop the picked-up object on the shooter unit when the claw assembly picks-up the object and the determined outcome is a winning outcome; and cause a winning game presentation display when the claw assembly does not pick up a prize object and the determined outcome is a winning outcome.

A dice shaker device and method for providing a randomized state of at least one die. The dice shaker device includes a dice plate, a dice plate actuator configured to apply a reciprocating force to the dice plate, a casing, a circumferential ridge surface extending around an outer perimeter of the dice plate, and a dice rolling space at least partly defined by the casing, the dice plate, and the circumferential ridge surface. The circumferential ridge surface can be arranged in parallel with an upper surface of the dice plate, and the circumferential ridge surface can have a width that is equal to or less than half a width of the at least one die that the dice shaker device is arranged to provide a randomized state of.

A “dual” gaming unit or machine is configured to implement both one or more traditional casino-style wagering games, such as games having outcomes determined primarily by chance and not skill, and one or more games which are traditionally not casino style games, such as amusement-type games or games having amusement-type game components, such as games where the outcome is determined substantially by skill. The wagering game portion of the gaming machine may award monetary awards to the player for winning wagering game outcomes, and the amusement portion of the gaming machine may be used to award promotional prizes to the player. A player rewards system may include such dual gaming units or other award dispensing mechanisms.

An arcade game includes a robot that can be controlled by a player to capture one or more items. The robot may include a stationary base, a lower member rotatably connected to the base to rotate about a first generally vertical axis, a torso member rotatably mounted to the lower member that rotates about a second axis that is generally horizontal; an arm member rotatably mounted to the torso member to rotate about a third axis that is generally parallel to the second axis. A hand portion may include hand-like pincers for grasping and releasing items and may include a sensor to sense contact with an item. A head portion may include a video screen that displays facial features. The head portion may include an image capturing device, such as a video camera.

A game machine having a display device in a housing includes a game processing portion performing game processing. The game processing portion calculates and displays a maximum monetary consumption amount per unit time by calculating using a maximum number of virtual game balls capable of being launched per unit time, a selected exchange rate and a base.

A claw gaming machine may comprise a cabinet, a claw assembly, prize objects, and a shooter unit. The machine may be configured to: determine an outcome of a claw game; allow an input device to control the claw assembly; end the claw game when the claw assembly does not pick up a prize object and the determined outcome is a losing outcome; cause the claw assembly to move and release the picked-up object away from the shooter unit when the claw assembly does pick-up a prize object and the determined outcome is a losing outcome, cause the claw assembly to drop the picked-up object on the shooter unit when the claw assembly picks-up the object and the determined outcome is a winning outcome; and cause a winning game presentation display when the claw assembly does not pick up a prize object and the determined outcome is a winning outcome.

A claw machine includes a chute and a sensor for detecting a won prize dropped to the chute. The sensor includes infrared units, a comparator, a calculating and judging unit, an actuating unit, an indicator, a controller, an integrated circuit board and a casing. Each of the infrared units includes an infrared transmitter for emitting an incident infrared beam with a carrier wave at a predetermined frequency and an infrared receiver for receiving a reflected infrared beam at the predetermined frequency. The controller instructs, controls, commands and manages the infrared units, the comparator, the calculating and judging unit, the actuating unit and the indicator. The infrared units, the comparator, the calculating and judging unit, the actuating unit and the indicator are supported on the integrated circuit board. The casing contains the integrated circuit board. The casing, which contains the integrated circuit board, is supported on a wall of the chute.
