A gaming system includes a network accessible sports betting server that allows players to anonymously place wagers on sporting events using an anonymous account identifier that is not associated with any personal information of the player. The player may use the anonymous account identifier to access an available monetary balance for wagering, view, filter, and place wagers on sporting events using various wagering game machines, and continue to use the account identifier to track all associated wagering transactions while a remaining balance remains or pending wagering transactions are outstanding. The gaming system enables the player to use mobile devices and casino gaming machines to interchangeably interface with the anonymous account, viewing the remaining balance, place wagers, etc.
