From the Super Mario Wiki, the Mario encyclopedia
The player must close all the application windows on a computer by using the stylus. Windows are closed in any order by tapping either the red "X" button on the top right corner or the "OK" button on the bottom, which sometimes pops up after attempting to close another window. Unlike most computer operating systems, in this microgame, all windows can be dragged from any part and tapping or dragging a window behind another window does not bring the tapped or dragged window to the front. If time runs out and any windows are still open, the player will lose.
