Most versions of Tetris, including the iconic NES and Game Boy editions, simply keep increasing in speed until even the best players are forced to eventually give in to their fate. But Arika’s Japanese arcade version, Tetris: The Grand Master, sets itself apart with a “Master Mode” that can actually be beaten by those with preternatural reflexes. Watching the above video, you’ll notice how the blocks start off so fast that they’re practically warping to the top of the pile instantaneously, only to speed up even more after a few minutes. That’s nothing, though, compared to the final challenge where the blocks disappear altogether after being placed, forcing you to play by memory as the credits roll. If you complete this ridiculous mode, you can truly and proudly say that you actually beat Tetris.
