If you're of a certain age, then one of your razor-sharp childhood memories may well be of unwrapping an original, brick-sized Nintendo Game Boy and playing its debut game, Tetris. (You may also remember the Tetris theme music -- which, it turns out, is actually based on a sad Russian folk song, "Korobeiniki.") Since that time, millions of man-hours have been devoted to those rotating Tetriminoes.
They weren't, it turns out, wasted hours: Jeremy Fordham, writing at The Beautiful Brain, recaps some of the research showing that Tetris actually transforms your gray matter, the 'plastic' part of your brain that changes as you learn. The main piece of evidence is a 2009 study showing that just thirty minutes of Tetris a day can produce positive changes in the brain. As Fordham explains, it's all about "the Tetris effect":
When a person initially starts to play Tetris, their brain consumes a huge amount of glucose in order to solve its fast-paced puzzles. Through consistent and limited daily practice, the brain begins to consume less glucose to perform just as well, if not better, at Tetris. After a few months the brain becomes so efficient at playing the game that it requires only a very small amount of fuel to perform the game’s rapid puzzle work.
The 'thickening' happens because the gray matter neurons become more interconnected: 'thicker' neural networks process Tetris problems faster. This isn't the only neurologically aspect of Tetris, either: In 2009, a study at the University of Oxford found that playing Tetris after a traumatic event might diminish traumatic flashbacks afterwards. Tetris, the lead author suggests, "specifically interferes with the way sensory memories are laid down in the period after trauma." I'll go out on a limb and speculate: Tetris is probably the sort of structured input that the brain responds to especially well. If only the rest of the world were as simple!
