A game system operates by: receiving character attribute selection data to be associated with a game character, wherein the character attribute selection data indicates a unique subset of a set of character attributes of a character attribute database; generating, based on the character attribute selection data, display data associated with the game character; facilitating, based on the display data associated with the game character, generation of a player token NFT associated with the game character; and preventing use of the unique subset of character attributes of the character attribute database in generating other game characters.

A game system operates by receiving a start game request for game corresponding to a game application having a player token NFT associated therewith; generating launch metadata; sending the launch metadata to a wallet associated with a user of a client device, the wallet containing a private key associated with the player token NFT; receiving, from the wallet, a launch response that is generated based on the private key; generating, based on the launch response, ownership check data; sending the ownership check data to a blockchain system that stores the player token NFT; receiving, from the blockchain system, an ownership validation response; enabling, via the game application, play of a game associated with the game application when the ownership validation response indicates ownership of the player token NFT is verified; and preventing, via the game application, the play of the game when the ownership validation response indicates the ownership of the player token NFT is not verified.

A non-fungible token (NFT) platform operates by: accessing, via a network interface, a plurality of game NFTs, each of the plurality of game NFTs including a playable instance of an associated game that is accessible by a user of a client device; generating, via a processor, display data associated with a customized collection display that contains the plurality of game NFTs; sending, via the network interface, the display data associated with a customized collection display to the client device for display via a graphical user interface associated with the client device; receiving, via the graphical user interface, a selection of one the plurality of game NFTs for play of the associated game; and facilitating, via the network interface, play of the associated game in conjunction with the client device.

Systems and methods to provide ledger-specific utilities for unique digital articles and other digital assets that are not fungible in an online gaming platform are disclosed. Exemplary implementations may execute instances of a game; manage user accounts associated with the users, including a first user account associated with a first user, wherein a first account inventory includes a first unique digital article; receive a first action request to use the first unique digital article in a first manner of usage; either permit or deny the requested first manner of usage, based on the type of unique digital article usage that is requested and on the type of decentralized ledger (or the specific decentralized ledger) on which the first unique digital article has been recorded.

Systems and methods for selling virtual items on multiple online sales platforms simultaneously are disclosed. Exemplary implementations may: receive a sales request that indicates the selling user will be offering for sale a particular virtual item through at least two online sales platforms simultaneously; assign ownership of the particular virtual item temporarily to a holding account; generate sales listings of the particular virtual item for publications on the at least two online sales platforms; effectuate the publications of the sales listings; receive indications of offers to purchase the particular virtual item; determine an accepted offer that is accepted; notify the at least two online sales platforms of whether the offers have been accepted or denied; identify a buyer's account of the buying user; effectuate assignment of the ownership of the particular virtual item to the buyer's account.

A system and method for tracking digital assets associated with video games. The digital assets may be in-game digital assets, such as in-game items or characters. The digital assets may be video game digital media assets representing moments of gameplay of a video game, such as video clips or images. The digital asset is created, and a distributed ledger tracking a history of the digital asset is created and stored across devices. A unique token for the digital asset can include a unique identifier and metadata identifying properties of the digital asset. Changes to properties of the digital asset, such as ownership, visual appearance, or metadata, can be identified in a request to update the history. A new block can be generated for, and appended to, the distributed ledger identifying the changes to the history of the digital asset. The new block can include hashes of previous blocks.

The present invention provides systems, methods and apparatus for a wearable band adapted to be worn by a user. The wearable band may include one or more biometric sensors such as a pulse monitor adapted to monitor a pulse of the user, and a transmitter adapted to wirelessly transmit pulse information from the pulse monitor to a mobile device such as a cellular telephone or PDA. The wearable band does not include a display for the biometric information. Numerous additional embodiments are disclosed.

A method for providing a puzzle game performed by a game server connected to a user terminal via a network includes the steps of: performing a user login process in response to receiving login information from the user terminal; and executing the puzzle game on the user terminal in response to receiving a game execution signal from the user terminal. Game action is performed in conjunction with player object groups if it is determined that a puzzle block elimination condition is satisfied according to a cumulative result of eliminating the puzzle blocks.
