Systems and methods for controlling an automated electronic networked central clearinghouse for clearing and reversing reversible exchanges of digital assets are disclosed. Exemplary implementations may: execute an instance of a game; receive an exchange request that indicates a first user offers a first digital asset for a reversible exchange on a fiat-currency-based online exchange platform; access a decentralized database to obtain asset-specific distribution rights for the first digital asset; generate publication information of the first digital asset for publication on the online exchange platform; receive exchange information regarding the reversible exchange; temporarily transferring the ownership of the first digital asset; determine whether to reverse the reversible exchange, and either (i) transfer the ownership of the first digital asset to the first user, or (ii) clear the reversible exchange by non-temporarily transferring the ownership to the exchanging user, and by distributing benefits in accordance with the asset-specific distribution rights.

A game controller is provided. The game controller includes a first handle, a second handle, and a function expansion module. The first handle and the second handle are connected to each other to jointly form an accommodating space. The function expansion module is disposed in the accommodating space between the first handle and the second handle. The function expansion module is connected to the first handle or the second handle.

The present application provides methods and corresponding systems for accessing services on a gaming device which, in certain embodiments, include the step or steps of receiving at least one item of identity verification data from a user of a gaming device; enabling at least one service, such as a wager-type game, on the gaming device based on a match between the at least one item of identity verification data received and at least one item of identity verification data obtained previously; displaying an interface screen comprising graphic objects associated with the wager-type game and at least one selectable element for the user to submit a gaming command and a wagering command during game play; obtaining at least one item of user change data from a user during game play; and prompting the user for identity verification data when a user change is suspected based on the at least one item of user change data.

A method for providing a single user multiple presence implementation may include providing access for a user identified by a user account to a virtual environment hosted by a computer. The method may further include generating multiple avatars for the user account to concurrently coexist and be operative within the virtual environment. The method may further include controlling the multiple avatars at least partly in response to input from the user. The method may further include communicating virtual environment data regarding more than one of the multiple avatars to at least one client operated by the user. An apparatus for performing the method may include a processor coupled to a memory holding encoded instructions for performing operations of the method on a computer configured as a network entity.

A method includes receiving, at a media device, a video game from a server via a network. The method includes installing, via the media device, the video game to a storage device associated with the media device. The method includes receiving, at the media device, a request to play the video game. The method includes sending an authorization request to the server from the media device via the network in response to the request. The method includes receiving authorization to execute the video game at the media device. The authorization is based on an identifier of the media device included in the authorization request being associated with rights allowing execution of the video game. The method also includes executing the video game via the media device in response to receiving the authorization.

A non-transitory computer-readable storage medium storing a program configured to cause a terminal device to execute a game in communication with a server device, the program includes: a first storing step of receiving from the server device at least one token generated and stored in the server device to store the token in a terminal storage unit; a transmitting step of transmitting to the server device information-to-be-transmitted including an updating instruction of game data of a user and encrypted information obtained by encrypting information-to-be-encrypted at least including the token; and a deleting step of deleting the token stored in the terminal storage unit, wherein the updating instruction includes a first instruction to update the game data stored in the server device when the token extracted by decrypting the encrypted information and the token stored in the server device are matched.

Methods for creating an interactive gaming environment are provided. In various embodiments, methods of the present invention may include initializing an interactive game application at a game server which is then characterized as having an active status, notifying a lobby server concerning the active status of the game server, registering the application with a universe management server via the lobby server, and allowing users to join the interactive gaming environment. The users joining the interactive gaming environment. may be identified by a server key obtained from the game server.

The present application provides methods and corresponding systems for accessing services on a gaming device which, in certain embodiments, include the step or steps of obtaining at least one item of identity verification data from a user of a gaming device; encrypting the at least one item of identity verification data; comparing the at least one item of encrypted identity verification data received and at least one item of encrypted identity verification data obtained and stored previously on an authentication device; enabling at least one service on the gaming device based on a match between the encrypted identity verification data, the at least one service comprising a wager-type game; and displaying an interface screen comprising graphic objects associated with the wager-type game and at least one selectable element for the user to submit a gaming command and a wagering command during game play.

An electronic gaming machine (“EGM”) includes a processor circuit, a port coupled to the processor circuit, and a memory coupled to the processor circuit. The port is configured to communicatively couple to a license dongle. The license dongle is configured to store a license associated with a game. The license is usable to allow the game to be played on the EGM. The memory includes machine-readable instructions that, when executed by the processor circuit, cause the EGM to perform operations. The operations include providing an identifier of the license dongle to a separate entity. The operations further include, responsive to providing the identifier of the license dongle, receiving an indicator of the license associated with the game. The operations further include initiating the game on the EGM using the license.
