Novel gaming networks, devices, and systems for enabling game play on wireless, mobile gaming devices based on the location of the device are described. A mobile gaming device can be used for wagering game play when the device is physically present in an authorized game play zone in a gaming environment and is used by an authorized and verified user. A gaming environment is divided into zones wherein a zone either allows wagering game play on a device or does not. A zone has multiple transmitters that transmit security signals that are detectable by a mobile device at all times while the device is in the zone. An appropriate wireless communication standard can be used to transmit the security signal, such as near-field magnetic communication. The device has at least one user identification and authentication mechanism to ensure that only an authorized user is using the device.
