Secondary gaming functionality is provided for a casino gaming machine (26) by a secondary controller (200) of the casino gaming machine. The secondary gaming functionality may function to provide a multi-game experience at the gaming machine or remotely at another gaming machine or other device, e.g., a smart phone (28), tablet, personal computer (32), and the like, via the casino gaming machine. The multi-game experience may comprise one or more secondary wager-based games in addition to the one or more primary wager-based game(s) provided by the primary gaming functionality of the gaming machine. The secondary controller functionality may cause the secondary wager-based game to be presented upon a single input player to the gaming machine which also initiates the primary game, whereby primary and secondary games are initiated seamlessly to the player via a single input.
