When I first got my hands on a computer, I couldn’t get enough of Tetris. I played it so much that my dreams were filled with those iconic, angular shapes dropping from above, maneuvering into place with each click. Even in my waking hours, I found myself spotting Tetris blocks everywhere, mentally arranging and stacking them amidst buildings on my way to work.
It’s been ages since I last played, but a new video series from PBS called “Braincraft” has reignited my interest by suggesting that Tetris could actually enhance our cognitive abilities. I mean, how could I have doubted it?
While I may not have believed Tetris was a brain booster back then, the evidence is compelling. Research indicates that individuals who engaged in Tetris for just 1.5 hours a week over three months experienced measurable changes in their brain structure. This isn’t too surprising, considering that sustained engagement in any activity can lead to such alterations. However, in this case, players showed a thicker cerebral cortex and improved efficiency in other brain areas, requiring less glucose for tasks that previously demanded more energy. Notably, those with PTSD saw a significant reduction in flashbacks after regularly playing the game, leading researchers to dub it a “cognitive vaccine.” It seems that Tetris occupies both our visual processing and working memory simultaneously.
The Addictive Nature of Tetris
So, what makes these games so addictive? It boils down to the “Zeigarnik Effect,” which explains our brains’ tendency to remember unfinished tasks better than completed ones. Tetris, alongside its colorful cousins like Candy Crush, satisfies our innate desire to organize, complete tasks, and achieve goals. The game is endlessly challenging yet gratifying. There’s something enchanting about a game that presents an unending stream of tasks while rewarding you with small victories. In Tetris, as the pieces hurry toward you unless you pause the gameplay, you have to act quickly, relying on your spatial judgment without overthinking. This keeps your brain engaged without the paralysis of analysis, allowing you to be both productive and active.
Weighing the Benefits Against Addiction
Does enhanced mental efficiency outweigh the potential for addiction? Like many players, I found myself dreaming in Tetris and subconsciously arranging my surroundings in more orderly ways, puzzled by my behavior. The simplicity of Tetris shapes seems to leave a lasting mark, as opposed to the fleeting enjoyment of Candy Crush, which disappears from my memory the moment I stop playing. One thing is for sure: it definitely doesn’t make me smarter.

In summary, engaging with Tetris may have cognitive benefits that extend beyond mere enjoyment. Its capacity to reshape brain structures, boost efficiency, and even help with conditions like PTSD makes it a worthwhile pastime, despite its addictive nature.
