A non-transitory machine-readable storage device having instructions stored thereon, which, when executed by one or more processors of a mobile device, cause the mobile device to:

• scan a physical item associated with a secondary game from a physical game card, wherein the physical game card is associated with a wagering game separate from the secondary game;
• determine, by the one or more processors of the mobile device and based at least in part on the physical item, an electronic copy of a game code;
• transmit, via a network communication interface of the mobile device, a first electronic message to a gaming system, wherein the first electronic message includes the electronic copy of the game code, wherein the gaming system is configured to automatically verify that the electronic copy of the game code is valid for the secondary game, determine an electronic indicator for the game code associated with the secondary game based, at least in part, on the electronic copy of the game code, and generate an electronic indication of an outcome for the secondary game based, at least in part, on the electronic copy of the game code;
• receive, via the network communication interface of the mobile device, a second electronic message, the second electronic message including the electronic indication of the outcome for the secondary game;
• and
• provide a representation of the electronic indication of the outcome for the secondary game on a display of the mobile device.

A mobile device comprising:

• one or more processors;
