Tetris. Remember those days when your mom would threaten to smash your Game Boy because you wouldn’t stop playing that highly addictive game with blocks of various shapes falling from the “sky”?

This game is arguably the most popular game ever, and it has withstood the test of time. Created in 1984 by Alexey Pajitnov, Tetris has been distributed all over the world for practically all kinds of interfaces. From the personal computer to handheld consoles to mobile phones – anything that can be used to play a game has been used to play Tetris.

For some, Tetris may just be that – a mere game. For others, Tetris means so much more. Various studies have been done to study the effects of Tetris on the human brain. One study claims that playing Tetris – especially during the first few times – makes the brain more efficient. Another study has shown that general cognitive functions become better due to regular playing. Yet another study showed preliminary results that patients deal with traumatic events better when Tetris is used as part of their therapy.

Here’s a firsthand testimony as to what Tetris can do to a real person. Have you ever heard of James Clewett? He is the 1999 Tetris world champion and a certified Tetris addict. This guy has not let his addiction get in the way of pursuing the rest of his life goals, though. If anything, he has gone beyond what the average person does (though he has already done that by becoming world champion). Pretty soon, this Tetris world champion is going to be a doctor as well – in the Dr. Sheldon Cooper way, that is.
