Tetris is a popular game in today's society.  Almost everyone plays Tetris.  Why are people so hooked on this game though?  BBC published a report that states that it's the game's ability to continually provide a frustrating piece for the players to deal with, followed by the gratification of putting a piece in the right spot that is so appealing and makes the player wants to continue playing.  As well, once the game is started, the player is compelled to complete it.   The reason why I chose the tag of Portable Computing is because many companies are creating apps which allows people to play Tetris via their mobile devices.  The reason why they create this is because so many people enjoy playing Tetris, so the companies create apps for people to play Tetris on the go.
