Tetrises

Tetrises refers to a class of falling block puzzle video games that originated with the Soviet Union game Tetris. The core gameplay involves players rotating and manipulating falling geometric shapes called tetrominoes, aiming to create complete horizontal lines of blocks without any gaps. When a horizontal line is completed, it is cleared from the playfield, and the player earns points. As the game progresses, the blocks fall faster, increasing the challenge. The objective is to score as many points as possible before the blocks stack up to the top of the screen, at which point the game ends.

The original Tetris was created by Alexey Pajitnov in 1984 and has since been adapted and released on countless platforms, becoming one of the most recognizable and commercially successful video games of all time. Variations in gameplay mechanics exist across different Tetris titles, such as the introduction of special blocks, different scoring systems, and multiplayer modes. Some versions feature competitive play where clearing lines sends "garbage" lines to an opponent's screen, hindering their progress. The enduring popularity of Tetris and its many iterations has solidified its status as a classic in the puzzle game genre.
