When I first acquired a computer, I found myself engrossed in Tetris, often dreaming of the game’s iconic shapes falling into place, aligning perfectly with each click. Even during my waking hours, I would visualize Tetris blocks fitting into the spaces between buildings as I walked down the street. Though I haven’t played in years, recent insights from a PBS video series called “Braincraft” have reignited my interest in the game, suggesting that playing Tetris can enhance cognitive abilities.
Initially, I was unaware of any potential cognitive benefits; I simply enjoyed playing. However, the impact of Tetris extends beyond mere entertainment. Research indicates that individuals who engage in Tetris for just 1.5 hours per week over three months can experience actual changes in brain structure. This is not entirely surprising, as prolonged engagement in any activity can alter brain anatomy. In this case, participants demonstrated a thickening in their cerebral cortexes and increased efficiency in certain brain regions, leading to a decreased need for glucose during tasks that previously required more energy. Notably, individuals with PTSD reported a significant reduction in flashbacks when playing the game regularly, earning it the title of a “cognitive vaccine.” This phenomenon occurs because Tetris occupies the brain’s working memory and visual processing simultaneously.
What Makes Tetris So Addictive?
But what makes these games so addictive? Scientists point to the “Zeigarnik Effect,” which explains our brain’s tendency to remember unfinished tasks more than completed ones. Tetris, like other popular games such as Candy Crush, directly appeals to our innate desire to organize, finish tasks, and achieve goals. The game is both challenging and rewarding, providing a continuous stream of incomplete tasks while simultaneously offering small accomplishments. In Tetris, the looming presence of falling blocks forces players to act quickly, utilizing spatial reasoning rather than overthinking. This engagement keeps the brain active and productive, rewarding players through achievement, which is universally appealing, all while presenting a visually captivating yet uncomplicated experience.
The Balance Between Addiction and Cognitive Enhancement
So, does the enhancement of cognitive function outweigh the addictive nature of such games? Many, including myself, have experienced Tetris-related dreams and found ourselves mentally arranging objects in our environment, often without understanding the underlying motivation. There seems to be a lasting impression left by Tetris’s simple shapes that lingers in our minds, unlike other games, such as Candy Crush, which fade from memory once play ceases. I can confidently assert that Candy Crush does not contribute to cognitive enhancement in the same way.

Conclusion
In summary, Tetris not only provides entertainment but also fosters cognitive growth, making it a worthwhile activity to consider revisiting. The balance between addiction and efficiency in thinking highlights the game’s unique appeal and potential benefits, contrasting with other modern games that may not offer the same developmental advantages.
