Abstract: 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.

Abstract: A wireless communication device communicates with an audio conferencing system via a wireless communication channel to initiate an audio conference hosted by the audio conferencing system. The wireless communication device includes a memory device that contains a contact list identifying a plurality of potential audio conference participants and their telephone numbers. A processor executes a wireless conferencing application and interfaces with the memory device to access the contact list, and transmits the contact list to a display for display to a user. An input device allows the user to select conference participants from the displayed contact list, and provide a selection signal to the processor indicative of the selected ones of the potential audio conference participants. The processor receives the selection signal and forms a conference list that identifies the selected ones of the potential audio conference participants and their telephone numbers.
