The guy must have a photographic memory to play invisible tetris. He probably memorized all the patterns of the game so its not like he processes it, but still pretty impressive.
... Invisible blocks ? hows that even possible. You'd have to memorize how the blocks are already laid out AND put the next block in the right spot.
Wow! ending is just simply amazing! Invisible blocks!? Like everyone said, you gotta memorize where you place your blocks....no life.
whooaaaaaaaaaaaaa!!! Look at that skill. That finesse. THAT SPEED! I think in case we ever get invaded by Russian Tetris terrorists that this is the only this man is our only hope of standing a chance.
