From Wikipedia:

According to Richard Haier, prolonged Tetris activity can lead to more efficient brain activity during play.

When first playing Tetris, brain function and activity increases, along with greater cerebral energy consumption, measured by glucose metabolic rate.

As Tetris players become more proficient, their brains show a reduced consumption of glucose, indicating more efficient brain activity for this task.

It sounds like Tetris really gives your brain a workout.
