Abstract: Described herein are systems and methods for synchronizing non-fungible token ledgers. The system can maintain a plurality of player profiles, with a first player profile identifying a plurality of non-fungible tokens maintained on a blockchain network. The system can provide a graphical user interface for display, including a plurality of slots corresponding to a first discard combination. The system can receive a request from a client device to discard a subset of the plurality of non-fungible tokens, with the subset corresponding to the plurality of slots. The system can determine that each non-fungible token of the subset satisfies a respective criteria of a respective slot of the plurality of slots. In response to determining that each non-fungible token of the subset satisfies the respective criteria of the respective slot, the system can store a respective identifier of each non-fungible token of the subset in a discard data structure.
