This app is designed with minimal interactions and navigations to focus you on an activity of guessing the order of four colored marbles. The game can finish is 6 or less minutes during a long public transportation commute. It will not add another layer of frustration to an already occupied mind. It only open a lightly engaging context to give you access to some unknown dimension.
