Lots of us here in Kotaku-land like Drop7, the randomized number puzzle game that we think is one of the best iPhone games. So we just had to share Daniel Walton’s video of his Lego Mindstorms NXT robot running up a ridiculous score of 5,205,955. We’ve never seen the video before, even though it’s from earlier this year. Even if you’ve never played Drop7, watching a machine do it is hypnotic and amazing. Scary, too.
