A block chain system allows mining for new valid values in a system such as a computer game or computer-based trading card system. Instead of each new value being added to the block chain being equivalent, each new value is one of a plurality of possible choices.

Provided is a game machine in which pieces of music prepared in a music distribution service provided only to members can be utilized in game play. A game machine provides a music selection opportunity to select music for play, such that multiple pieces of music are included as options in a music distribution service, which is provided separately from music games as a service that distributes multiple pieces of music only to user terminal devices that have passed member authentication. In addition, the game machine acquires musical score data for play corresponding to music for play from a game distribution system connected via a network. Furthermore, the game machine acquires music data corresponding to music for play from a music distribution system connected via the network, such that a music game is provided according to the combination of the music data and the musical score data for play.

Systems and methods for maintaining contests including non-fungible tokens (NFTs), determining that an outcome of a contest indicates a tie, and establishing a placeholder are disclosed. The NFTs can be associated with attributes and may be stored on a blockchain. The system can receive a request and selections of NFTs for entering a contest. Each NFT can be associated with a player profile and satisfy a selection rule. The system can generate a fantasy sports lineup including NFTs and modify a restriction condition for each NFT. The system can determine that an outcome of a contest indicates a tie and calculate edition number totals to determine a winner of the tie. The system can determine that an NFT has been transferred to a player profile. The system can modify a lineup to include a placeholder in lieu of the NFT.

Disclosed are a game data verification method performed by an electronic device. The method includes: generating a target sequence of target nodes in response to a game start instruction; acquiring target game data corresponding to each of the target nodes, the target game data including game state data and encrypted state data; performing authenticity verification on the target game data of a current target node according to the encrypted state data of a previous target node and the game state data of the current target node; performing accuracy verification on the target game data of the current target node according to the game state data of the current target node and game logic; and after determining that all the target game data corresponding to the target sequence is authentic data and accurate data based on an authenticity verification result and an accuracy verification result, determining that the game verification succeeds.

Embodiments of the present invention monitor and dynamically allocate computing resources to a game service. A game service provides a remote gaming environments to which users connect over a wide area network, such as the internet. A game session runs a single instance of a game title. The game session runs the video game code responsible for creating the playing experience for the users. In another embodiment, the number of active game sessions is monitored and computing resources are allocated dynamically as the number of sessions increases or decreases.

An authentication system includes first and second terminals, and an authentication subsystem. The authentication subsystem: generates a first token based on reception of a code image authentication start request, generates and stores a code image key in association with the first token, generates and stores a code image including the code image key at a URL of the storage unit, transmits the first token and the URL to the first terminal, registers the received first token as a key in an information transmitting and receiving unit, checks whether a received ID of the second terminal is a unique ID, when the received unique ID of the second terminal is the unique ID, checks whether the received code image key is stored in the storage unit, and transmits a first response code to the information transmitting and receiving unit using, as a key.

Systems and methods for using reduced hops to generate an augmented virtual reality scene in a head mounted display. The head mounted display is used for game play via a game cloud system. The head mounted display includes a communications circuit for sending real-world media associated with a game program via a network. The real-world media is processed by the game cloud system and streamed directly from the communications circuit to the game cloud system. The head mounted display further includes a game processing circuit coupled to the communications circuit. The game processing circuit is used for decoding computer-generated interactive media received from the game cloud system via the network. The game processing circuit drives a portion of interactivity associated with the game program by superimposing the computer-generated interactive media on the real-world media. The computer-generated interactive media is generated based on the real-world media.
