Tetris is the kind of game that you'll never forget your first experience playing. At first you'll ask yourself why anyone would find such a simple, basic game would be challenging or interesting. But then then pace of the game starts speeding up, and soon enough you realise that you can't keep up.
Blocks start piling up and you start panicking, making more and more elaborate mistakes. And then the dreaded words appear on the screen: Game. Over. You're frustrated and angry and naturally you start playing again to try and do better. That's Tetris, and it is back again in Tetris Ultimate to haunt your waking moments and even your dreams.
