An events agent core library of software functions, when executed by at least one processor of a client device, receives notifications of in-game events from game content software downloaded to the client device from a game supplier server and executing on the client device providing wagering game play to a user of the client device. Based on the notifications, the events agent core may report at least some of the in-game events to a front-end set of processor-executable instructions downloaded to the client device from a gaming operator server different from the game supplier server, the front-end set of processor-executable instructions being configured to cause the at least one processor of the client device to implement an out-of-game response based on at least one of the reported in-game events.
