We at TGD have found ourselves dreaming about those little falling blocks, so it comes as no surprise that Tetris is now the best-selling mobile game of all time.
More than 25 years after its birth, the horrifyingly addictive game is still going strong, and has clocked up an amazing 100 million downloads.
"Tetris on mobile will never go away," said Henk Rogers, CEO of Blue Planet Software, which manages the game's licensing. "As mobile devices get into the hands of more people, so does Tetris.
"People are always looking for ways to fill their time — be it in waiting rooms or on the bus — and with the advent of touch screens and improved platforms, our eyes are opened to a whole new way to develop games."
Created in 1984 by Russian-born mathematician Alexey Pajitnov, Tetris gained a whole new lease of life with the widespread advent of cellphones.
While many of us credit it with swallowing up our days and turning our brains to mush, it's actually been found to be good for you: last year, a study in BMC Research Notes showed that long-term Tetris players had increased efficiency and a thicker cortex in areas of the brain linked to critical thinking and coordinated movement.
