Tetris is a tile-matching puzzle where seven tetromino shapes descend into a rectangular well. You rotate and position these blocks to create full horizontal lines. When a line fills, it clears, freeing space and awarding points. The constant stream of pieces forces quick spatial decisions, refining pattern recognition and planning under gentle pressure.
