Effect of Tetris on the brain
According to research from Dr. Richard Haier, et al. prolonged Tetris activity can also 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. Even moderate playing of Tetris (half-an-hour a day for three months) boosts general cognitive functions such as "critical thinking, reasoning, language and processing" and increases cerebral cortex thickness.
In January 2009, an Oxford University research group headed by Dr. Emily Holmes reported in PLoS ONE that for healthy volunteers, playing Tetris soon after viewing traumatic material in the laboratory reduced the number of flashbacks to those scenes in the following week. They believe that the computer game may disrupt the memories that are retained of the sights and sounds witnessed at the time, and which are later re-experienced through involuntary, distressing flashbacks of that moment. The group hopes to develop this approach further as a potential intervention to reduce the flashbacks experienced in posttraumatic stress disorder, but emphasized that these are only preliminary results.
Professor Jackie Andrade and Jon May, from Plymouth University's Cognition Institute, and PhD student Jessica Skorka-Brown have conducted research that shows that playing tetris could give a "quick and manageable" fix for people struggling to stick to diets, or quit smoking or drinking.

Research has shown that the CFS brain awake looks like the normal brain asleep. I heard that someone was having patients play videogames to wake up the brain, so I tried it, and saw noticeable improvement in my thought process. It has to be something like Tetris, where the game determines the speed, rather than something like Solitaire, where you can sit and stare at it for hours before making your next move.
