Tetris is one of the most recognizable and influential video games ever created. Developed by Russian software engineer Alexey Pajitnov in 1984, the game tasks players with manipulating falling tetrominoes (geometric shapes composed of four square blocks) to create horizontal lines without gaps. When such a line is created, it disappears, and the player earns points. As the game progresses, the tetrominoes fall faster, making the game increasingly challenging. Tetris has been scientifically proven to engage the brain in a unique way, potentially improving cognitive skills and spatial awareness.
