The "host device" is the central command station for your gaming adventure! This is the device on which you need to register the app using the licence key. You can designate a laptop, phone, or tablet as your host device. Just remember, during the game, this device is dedicated solely to leading you through the twists and turns of Outsmarted—so no sneaky text checking or this might disrupt gameplay! If you think you might need your phone during play, we recommend using a different device as your host.
