Video game tasks are delegated using a sharing service. A first computing device is configured to execute a game application. The first computing device can receive a request from a first user to delegate play of the game application to a second user so that the second user can attempt to complete a game task on behalf of the first user by controlling the game application from a second computing device that is associated with the second user. Control of the game application can be made available from the second computing device to the first computing device via a sharing session that is created and managed by a sharing service to which the first computing device and the second computing device are connected.
