It doesn't really seem to be very good at guessing at all, I kept with my number (77) and tried 5 times, the number never came up. Also, you might want to look at a way of preventing people from saying higher and lower to a point where it gets stuck, one thing I test was on 92, I said lower, 91, then higher, 92, and it was just stuck in a loop between them.
There's no audio and the text is very basic, you might get better results with a lower range as well, 1 to 1000 seems a bit wide, and unlikely to get results.
