A location-based game system is provided. Such a system may take the form of any device (e.g., a wireless telephone) that includes a locating device (e.g., a GPS system). One such location-based game may operate such that the actual, physical location of a user on a physical playfield corresponds to the location of a virtual character on a virtual playfield. Such location based games are referred to herein as actuality games. In one multiplayer actuality embodiment, two game devices may communicate location, and other, information to a remote database such that the two user's may interact on different physical playfields, but play on the same virtual playfield. A number of wireless communications protocols, self-configurations, and auto-download software applications are also provided to optimize integration with, for example, a wireless telephone.

A system and method for providing peer recommendations in a network environment are provided. A set of activity data and user generated content (UGC) associated with the set of activity data may be stored in memory in a database. Such UGC may depict the activity. The set of activity data may be received regarding an activity that a user and at least one peer have participated in simultaneously on the network environment. Corresponding UGC may also be received. A user-peer indication may be identified based on identifying a peer with whom the user experienced a significant event during the activity. Such significant event may be based on one or more event factors. A peer recommendation may be generated based on the peer indication and such peer recommendation at least a portion of the UGC associated with the significant even may be provided to the user.

It is an object of the present invention to provide a game apparatus and a game system in which a player who operates a game apparatus without having a game program can obtain the same benefit such as an item which is originally obtained through a communication play, when the game apparatus which does not have the game program downloads a part of the game program from a game apparatus which has the game program and performs the communication play with the game apparatus having the game program.

Disclosed are a method for changing a game parameter and a client for performing same. The client comprises: a processor for executing a game program; and a transceiver for communicating with a blockchain node of a blockchain network storing a first blockchain, wherein the processor may authenticate a user account and perform a first event of the game program accessed by the user account, the transceiver may transmit, to the blockchain node, a completion signal of the first event including information about the client when the first event is completed and receive, from the blockchain node, a request signal for generating a second event, the processor may generate the second event on the basis of the request signal for generating the second event, and the transceiver may transmit, to the blockchain node, information about the second event.

The present disclosure provides a method of synchronizing an online game, and a server device, that do not require centralized information management, reduce the processing burden on each device during online communication, and allow for continuation of processing in an offline environment. A method, according to the present disclosure, of synchronizing an online game that allows for transmission and reception of information related to game processing between a first client terminal and a second client terminal via a server includes: receiving, from the first client terminal connected online, first information related to game processing on the first client terminal; determining whether the first information is information that determines a game status; and storing the first information on the server and transmitting the first information to the second client terminal when the first information is determined to be information that determines the game status.

A device for transmitting game data files between a plurality of smart devices through a short-range wireless communication network can be provided. The device comprises: a transmission and reception unit provided and operated in a smart device of a first user, transmitting a request for stored information of the game data files from the smart device of the first user to a smart device of a second user, and receiving the stored information from the smart device of the second user in response to the request for the stored information; and a processor for selecting at least one of the game data files to be received from the smart device of the second user, according to the stored information, and controlling the transmission and reception unit such that the transmission and reception unit receives the selected at least one game data file, wherein the game data file includes an executable file and at least one of resource files, the executable file is mapped to the at least one resource file according to a game scenario, the stored information includes a list of the game data files installed in the smart device of the second user, and the processor selects the at least one game data file by comparing the stored information with an executable file and/or a resource file installed in the smart device of the first user.

The present disclosure provides a method of synchronizing an online game, and a server device, that do not require centralized information management, reduce the processing burden on each device during online communication, and allow for continuation of processing in an offline environment. A method, according to the present disclosure, of synchronizing an online game that allows for transmission and reception of information related to game processing between a first client terminal and a second client terminal via a server includes: receiving, from the first client terminal connected online, first information related to game processing on the first client terminal; determining whether the first information is information that determines a game status; and storing the first information on the server and transmitting the first information to the second client terminal when the first information is determined to be information that determines the game status.

A communication play is performed between a master machine and a slave machine. The slave machine can obtain an item according to the result of the communication play and the item is deposited to the master machine. After the communication play ends, if a cartridge is mounted to the slave machine and the master machine and the slave machine perform communication, the item that has been deposited to the master machine is delivered to the slave machine.

Electronic devices can facilitate collective and accurate scorekeeping. A first electronic mobile device can communicate (directly or indirectly) with a second electronic mobile device. Respective users can use the devices to identify when and/or how a score is to be adjusted. The input can be processed at a mobile device or central server to determine whether and/or how to adjust a score. Score adjustment can depend on whether any other input includes inconsistent information. The score adjustments can be pushed to one or more mobile devices. In this manner, all mobile devices can display a consistent and current score.

A method or system for building a network between a plurality of portable computing devices to facilitate a multiplayer game includes each portable computing device: receiving an audio signal at a microphone at the device; matching the audio signal to one of a plurality of pre-stored games, each game associated with a game network identifier; creating a new network identifier utilising the matched game network identifier; and creating a network using the new network identifier if the network does not exist or joining the network using the new network identifier if the network does exist.
