Tetris turns 30 today. Yes, you read that right. And yes, you are old.
The game hit the NES over two decades ago, but it was the Game Boy version in 1989 that cemented it as a staple of puzzle video games. It went on to sell over 30 millions copies on Game Boy alone, with over 170 million downloads on all platforms as of 2010.
Here's to you, Tetris. May you always have a line block at the ready.
