Abstract: A system is described for generating one or more rewards for use in a first application on a user processing device in response to user engagement of a second application on the user processing device. The system comprises a user processing device and a reward server arrangement. The user processing device stores instructions defining a first application and a second application. The user processing device further stores instructions defining a content delivery and reward implementation module. The content delivery and reward implementation module is operable to display on a user processing device content obtained from a content and reward delivery server arrangement comprising at least one server, to obtain one or more content viewing rewards from the content and reward delivery server arrangement, and to make the one or more content viewing rewards available for use in the first application. The user processing device further stores instructions defining a monitoring module and a reward module.

Abstract: A processing device is described storing instructions defining a first application and a second application. Engagement of the second application by a user is effective to generate one or more rewards for use in the first application. The processing device further stores instructions separate from the second application defining a monitoring module and a reward generating module. The monitoring module is operable to determine a measure of an engagement of the second application by the user. The reward generating module is operable to calculate one or more rewards in dependence upon the determined measure of engagement and to make the calculated one or more rewards available for use in the first application.
