On this day, 41 years ago, June 1, 1984 (May 2, 1984 in the lunar calendar), the birth of Tetris was reviewed. Tetris (Russian: ¢Ü §Ö§ä§â§Ú§ã) is a popular video game console and handheld game console game around the world. It was invented by Russian Alexei Pakitnov, hence its name. The basic rules of Tetris are to move, rotate and place the various squares automatically output by the game to arrange them into one or more complete rows and eliminate points. Because it is easy to use and suitable for all ages, it has become a household name and is popular around the world. Due to its mathematical nature, dynamic nature and popularity, Tetris is often used as an exercise subject for game programming. The sensation and economic value that Tetris once caused can be said to be a major event in the history of games. It may seem simple but it is endlessly varied and addictive. I believe most users still remember the Tetris era when they were so obsessed with it. Tetris is extremely easy to get started, but it is difficult to master the operation and placement skills skillfully. As a well-known popular game suitable for all ages, its popularity can be said to be unmatched by any game in history. The charm of small squares lasts forever. As of 2009, Tetris has sold 125 million copies and is loved by players in more than 50 countries and regions. It is available in more than 50 languages and runs on dozens of game platforms, from handheld, arcade, personal computers, to mobile phones and PDAs. Rogers said mobile devices have become the new major platform for Tetris, with sales in the field exceeding 75 million units and growing rapidly. On the official North American and European websites of Tetris online version, more than 1 million people play the game every day. Who knows which god created such an excellent entertainment tool? As the name suggests, Tetris was naturally invented by the Russians. This great man was named Alexey Pazhitnov (§¡§Ý§Ö§Ü§ã§Ö§Û§±§Ñ §Ô §Ú§ä§ß§à§Ó English: Alexey Pazhitnov). The original name of Tetris is Tetris in Russian is Traveller (Tetris in English). The name comes from the Greek word tetra, which means "four", and the author of the game likes tennis best. So he combined the two words tetra and tennis into one and named them Tetris, which is where the name of Tetris came from. Journey review: In the early 1980s, I studied artificial intelligence in the computer laboratory of the Academy of Sciences of the former Soviet Union. It was one of the few Soviet institutions at the time that could communicate with the outside world, so people would occasionally send us new hardware. We would write simple programs to evaluate the performance of these hardware, which became an excuse for me to develop games. I have loved jigsaw puzzles since I was a child, especially five-frame jigsaw puzzles. Back then, three sets of these geometric games could be purchased in toy stores in Moscow for just a ruble. In June 1984, it suddenly occurred to me that maybe we could develop a computer game using the same concept. But getting 12 five-grid panels to rotate at any time was a bit too complicated, so I used a four-grid panel model. There are 7 types of squares. In addition, the Electronika60 computer I originally used when writing Tetris didn't have the right graphics and only had a display that could display text, so I used letters to combine the squares. Next, I designed how to operate these squares: select the squares, flip the squares, and rotate the squares. But it only takes 20 seconds for the entire screen to fill. And once you fill a row, it's dead. If that's the case, why leave it on the screen? So every time I fill a line, I make the corresponding line disappear automatically, which became the key to the whole game. I was a very good programmer at the time, and it took me about three weeks to achieve this effect on the screen. I pretended to be debugging my own program, but in fact, I was addicted to it. Others became addicted after getting started. This game is abstract, which is its quality. Everyone was attracted by it. I don't know how to promote it. I was worried that promoting the game would get me in trouble, but PC versions of Tetris have been smuggled into Hungary, and Western companies have started producing unauthorized versions. Then, institutional reform began, so I awarded the 10-year copyright to the game to the government. This also became one of the first software exported by the Soviet Union. The American company Spectrum HoloByte was responsible for developing an early version of "Tetris", and the company has also had a profound impact on the way the game is promoted. I think these dolls and churches are a bit tacky, but they really help sales. They chose the 19th century Russian folk song "Sellers" as the theme song. Nintendo later joined "Tchaikovsky's Nutcracker". This embarrassed me: When all children around the world hear this music, they shout,"Tetris! Tetris!" This is not good for Russian culture. I didn't make a lot of money at first, but I was happy because I mainly wanted to see people like my games. Tetris plays a very important role in breaking the depression of ordinary people sitting in front of computers. For non-professionals accustomed to paper and pen, it's a scary thing. But such a simple and beautiful thing appeared on the group screen, but broke this gap.
