Every year on July 18, video game fans celebrate one of the world’s most famous puzzle games—Tetris. It was on this day in 1985 that the electronic version of the game was released, which later became an international hit and captivated millions of people. Although the game itself was created a year earlier, July 18 is considered its official birthday. Over the course of more than four decades, “Tetris” has not only remained on our screens but continues to be released on modern consoles, smartphones, and computers.
Today, it’s not just a game—it’s a true part of global culture. “Tetris” ranks among the most successful video games of all time, and even people who have never been into gaming recognize it.
How Tetris Came to Be
The game was created by Soviet programmer Alexey Pajitnov, who worked at the Computing Center of the USSR Academy of Sciences. He created the first version of “Tetris” on June 6, 1984. The idea came to him after he became fascinated by puzzles involving geometric shapes that had to be fitted together. Pajitnov decided to bring this concept to the computer screen.
He formed the game’s name from two words. The first part comes from the Greek word “tetra,” meaning “four,” since all the shapes consist of exactly four squares. The second part was borrowed from his favorite sport—tennis. At first, no one expected that a simple puzzle would become a global sensation. However, the game spread very quickly among programmers, and within a year it began to be released on various platforms.
What’s the secret to its popularity?
The rules of “Tetris” are so simple that you can understand them in literally a minute. Shapes of various forms fall onto the screen from above. The player must rotate them to fill horizontal lines without leaving any empty spaces. When a row is completely filled, it disappears, and the player scores points.
The game’s speed increases with every passing minute, so you have to make quick decisions. It is this simplicity that has made “Tetris” a universal game. It’s equally easy for both children and adults to play, regardless of age or experience.
How Tetris Conquered the World
After the release of the electronic version on July 18, 1985, the game began to spread rapidly beyond the borders of the Soviet Union. True global success came in 1989, when Tetris became one of the flagship games for Nintendo’s Game Boy handheld console. It was then that millions of people were introduced to the puzzle game for the first time. For many Game Boy owners, “Tetris” was the first video game they ever played.
Over time, the game appeared on virtually every possible device—from home computers and arcade machines to modern smartphones, tablets, TVs, and even smartwatches. Today, there are hundreds of official and unofficial versions of “Tetris,” but the core concept remains the same.
Interesting Facts About Tetris
"Tetris" is considered one of the best-selling video games in history. According to various estimates, mobile versions of the game have been downloaded over 500 million times, and the total number of copies across all platforms runs into the hundreds of millions.
Scientists have repeatedly studied the game’s effect on the brain. Some studies have shown that playing regularly can improve spatial reasoning, decision-making speed, and concentration. There is even what is known as the “Tetris effect.” This is a phenomenon in which, after playing for a long time, a person begins to mentally see familiar shapes or unconsciously imagines how to stack various objects around them.
Researchers have also explored the possibility of using “Tetris” as an adjunct tool to reduce intrusive memories following stressful events. However, these findings are based on individual scientific experiments and are not a substitute for professional medical or psychological care.
How Tetris Day Is Celebrated
This holiday has no official status, but it is happily celebrated by video game fans around the world. On July 18, many people relaunch their favorite game, tackle challenging levels, or compete with friends for a new high score.
Gaming communities host online tournaments, themed livestreams, and marathons. On social media, users share their own stories about how they first discovered “Tetris,” reminisce about old consoles, and post photos of the legendary Game Boy. Some video game and technology museums also organize exhibitions dedicated to the history of the puzzle game’s creation.
Why Tetris Remains Popular
Despite the vast number of modern games with realistic graphics and complex storylines, “Tetris” remains relevant to this day. Its success is due to simple yet highly addictive gameplay that never gets old, even after many years.
Each game lasts only a few minutes, but you almost always want to play again and beat your high score. That’s why Tetris has remained an icon of video games for over 40 years and proves that a truly great idea doesn’t need complex special effects or high-end graphics. "Tetris" is an example of how a simple puzzle game, created by a single programmer, was able to bring together millions of people around the world and forever make its mark on the history of digital culture.
