Think you're smarter than a mindless iPhone app? Think again! HEXPAWN is just that: a computer that fits in your pocket and knows almost nothing. What does it know? Only the moves a pawn can make in chess. Oh yeah, and one other thing. Like the proverbial elephant or your seventh grade algebra teacher, it never forgets. So play HEXPAWN. You'll probably win the first few games. But every time you win, HEXPAWN remembers. And it will never make the same mistake twice... which means eventually, HEXPAWN will be impossible to defeat. Don't believe me? Go ahead. Try. See how long you can last against this brainless robot. I bet it won't be long. Enjoy this small dip into the world of machine learning and the eventual domination of the human race at the hands of our machine overlords.
