One of the world’s first videogames, Tetris (俄罗斯方块), has turned thirty years old, and its brand is anything but old school. But what’s kept people swiping and clicking to ensure each row of blocks stays aligned and disappears into the virtual world since its development in 1984 Soviet Russia A combination of new platforms and an attracting psychological appeal. Maya Rogers, the CEO of Blue Planet Software, the sole agent of the Tetris brand, said the protection of the game’s core over the last three decades has aided its longevity. As mobile and social become two of the largest sources for gaming these days, Tetris isn’t showing any signs of losing its appeal. Currently appearing on over 50 different gaming platforms, from the 1983 Nintendo Entertainment System (NES) to smartphones, Tetris is sold on over 425 million mobile devices. More than 20 billion games of Tetris Battle have been played on Facebook, too. There’s something psychologically entrancing about the game, that’s kept people hooked through the years. "Play a game of Tetris," said Rogers, "and satisfy your craving to create order out of chaos." Plus, there’s the added quality of playing Tetris and never feeling wholly fulfilled. "There’s no correct move that you can make," said Neubauer, a loyal player of the game who work as a senior analyst at Saibus Research, an independent research and advisory firm, "The quest for the perfect move never ends." Tom Stafford, a professor of cognitive development and psychology at Sheffield University in the U.K., says that Tetris has been around so long because it transports garners into a different realm when they play. "It’s a world of perpetually generating uncompleted tasks," he said. As he’s said in the past, too, "Tetris is the granddaddy of puzzle games like Candy Crush saga—the things that keep us puzzling away for hours, days and weeks." "Tetris is pure game: there is no benefit to it, nothing to learn, no social or physical consequence," he added. "It is almost completely pointless, but keeps us coming back for more."
A.to imply that Teris is out of date and lost popularityB.to represent a specific group of attracting puzzle gamesC.to suggest that Teris is the inspiration of new gamesD.to declare that there are different types of Tetris
