From Wired:

Playing Tetris actually gives you more brain to work with, says a new study to be published later this week.

The study, funded by Tetris’ makers and authored by investigators at the Mind Research Network in New Mexico, shows that playing the classic puzzle game had two distinct effects on the brains of research subjects: some areas in the brain showed greater efficiency (the blue areas in the diagram above), and different areas showed thicker cortexes, which is a sign of more grey matter (red).

This, says the doctors who undertook the study, shows that focusing on a "challenging visuospatial task" like a videogame can actually alter the structure of the brain, not just increase brain activity.
