Game Description

Tetris is a classic puzzle video game where players manipulate falling tetrominoes (geometric shapes composed of four square blocks) to create complete horizontal lines. When a line is completed, it disappears and the player earns points. The game ends when the tetrominoes stack up to the top of the playing field and no more shapes can enter.
