Tetris®

How many times did you tell your Tetris screen to give you the shape you needed to clear multiple levels at a time? Believe it or not, Tetris has real-world applications to teach people spatial orientation. You start with a blank screen. Then various shapes, composed of four smaller squares arranged in different patterns, start falling from the sky. Your job is to arrange the shapes so they fit together a certain way that fills in rows and columns at the bottom of the screen.

Your reward for getting good? The shapes fall faster! You earn points for each row you clear, and you get bonuses for clearing multiple rows at the same time. Today's kids might think this game is monotonous, but Tetris kept players busy for hours at a time with the challenge of getting better and faster.
