Tetris
Overview
Tetris is a puzzle video game developed in 1984 by Soviet computer engineer Alexey Pajitnov. Blocks of seven shapes (tetrominoes) fall downward, and the player rotates and moves them to complete horizontal lines, which then disappear. With its simple rules and addictive gameplay, it achieved explosive worldwide popularity and is regarded as one of the most successful and influential works in gaming history.

The Birth of the Game and Its Creator
Tetris originated as a computer program implemented by Alexey Pajitnov while he was working at the Soviet Academy of Sciences. He named it 'Tetris', combining the ancient Greek word 'tetra' (four) with 'tennis', a sport he enjoyed. The early version ran on the black-and-white screen of the Elektronika 60 computer, and with the help of other developers it was later ported to various platforms such as the IBM PC, spreading widely.
Game Rules and Progression
Tetris takes place on a 10×20 grid. Seven types of tetrominoes—I, O, T, S, Z, J, and L—fall at random, and the player stacks them by moving left or right, rotating, and adjusting the drop speed. When a line is completely filled, it is cleared and the player earns points. Clearing multiple lines at once yields higher scores. The game ends when blocks pile up and reach the top of the grid, and the speed gradually increases, heightening the tension.
Cultural Impact and Copyright Disputes
Tetris became a worldwide phenomenon in the late 1980s when it was included as a bundled title with the Nintendo Game Boy. The Game Boy version sold millions of copies, and the game was later ported to virtually every gaming platform, with total sales estimated at over 500 million units. Tetris also established standards for modern puzzle games, including piece fall speed, next-piece preview, and the hold function. During this process, rights disputes arose among the Soviet government and various companies, often cited as one of the most famous copyright cases in gaming history.
Official Rules and Esports
The Tetris Association established official rules and has hosted the Classic Tetris World Championship since 2010. In the early years, competitors played the NES version, and as of 2024, various modes such as Tetris Effect: Connected and Tetris 99 have become active esports titles. In particular, Tetris, as a game that tests human limits, has seen the development of advanced techniques such as 'tapping' and 'hypertapping'.
Latest Trends
As of 2024, Tetris remains actively serviced. In August 2024, Tetris 99 gained great popularity as a Nintendo Switch Online exclusive. In 2025, a mobile version of Tetris introduced cloud-based multiplayer and a 128-player battle royale mode. In particular, in early 2025, AI researchers published results showing that reinforcement learning could achieve near-perfect play in Tetris, drawing considerable attention. Additionally, research continues on Tetris's effects on intellectual activity and brain health, exploring its potential as a cognitive training tool. Within the gaming industry, interest in the original Tetris has also been reignited amid the remaster craze for classic games.
