The "Tetris Effect" is a phenomenon where people who play the game Tetris for extended periods start to see the game's shapes and patterns in their everyday lives. After playing, they might visualize Tetriminos—the colorful blocks used in the game—while doing mundane tasks, like walking or even dreaming. This effect highlights how immersive experiences can influence our thoughts and perceptions. This phenomenon isn't limited to Tetris; it can occur with other activities too, such as playing video games or engaging in repetitive tasks. The brain becomes so accustomed to the patterns that it continues to process them outside of the original context, showcasing the power of focused attention and memory.
