This disclosure describes systems, devices, apparatuses, and methods of adjusting a center of gravity associated with a user device, such as a gaming controller. A movable weight may be moved to a first position associated with a first center of gravity of the user device and to a second position associated with a second center of gravity of the user device. The movable weight may be moved manually or automatically. The center of gravity may be adjusted based on a gameplay event or context or based on a user event or context. The user may receive feedback from an application via the user device.

A game processing device changes a movement direction of a moving object from a first direction, which is a movement direction of the moving object, to a second direction based on an operation direction of the controller if an operation of the controller in a direction that is different from the first direction is detected.

A game processing device changes a movement direction of a moving object from a first direction, which is a movement direction of the moving object, to a second direction based on an operation direction of the controller if an operation of the controller in a direction that is different from the first direction is detected.

A game processing device includes circuitry that is configured to set a state of an item in a game field, when a first operation of a controller in a first direction is detected, to being ready to start a game operation. The circuitry is further configured to start the game operation using the item when a starting condition of the game operation is satisfied; and cancel the state of the item when a second operation of the controller in a second direction, that is different from the first direction, is detected before the starting condition of the game operation is satisfied.

A game processing device determines a movement range of a moving object in a game field using movement range information indicating the movement range of the moving object in the game field. Further, the game processing device arranges a game medium operated by a player in the game field so that a relative position of the game medium with respect to the movement range satisfies a predetermined condition.

A game processing device determines, for a moving object in a game field, a first region in which a first operation performed on the moving object is valid. The first region is set in the game field in a movable region of the moving object. Further, the game processing device determines validity of the first operation based on the first region and a position of the moving object. In addition, the game processing device validates a second operation that is different from the first operation performed on the moving object if the first region reaches a second region that is within the first region.

The present disclosure relates to providing a game service using a location-based service in an electronic device, and the electronic device includes: a communication unit configured to communicate with at least one client; a memory configured to store a game management policy; and a processor configured to generate an event based on a location of the at least one client using a game service, and the stored game management policy, and the processor is configured to determine an amount of service use corresponding to the location while generating the event, and, when the amount of service use exceeds a reference value, to change at least a portion of the game management policy.

An information processing system generates at least one virtually arranged object based on at least one event log within a unit period of actual time among event logs about in-game events that occur based on in-game activities in a virtual game space, arranges one or more of the at least one virtually arranged objects in a virtual field which is a unit for generation of an output image to be shown on a display, stores the virtual field together with the one or more of the at least one virtually arranged objects as a past object based on arrangement of a reference number of the virtually arranged objects in the virtual field, and arranging one or more of the at least one virtually arranged objects in another virtual field when the reference number of virtually arranged objects are arranged in the virtual field.

A method for remotely directing a fishing tournament makes use of a data network over which participants transmit submissions indicating sizes of fish caught. The submissions may include digital images of fish, and size may be determined from a scale established using a reference object depicted in the image. The data network may also be used to register participants and provide them with tournament results. Participants may register for a fishing period, or multiple fishing periods of the tournament, and may be issued a code to be displayed in images of fish. Validation of entries may include an examination of metadata in submitted digital images.
