Good guess! Thanks for testing. Everything seemed to work right, so the Real One is coming on my blog next. I think it will be, guess between 1 and 10,000. Should still be discoverable in about 13 guesses, but I don't think everyone will follow the optimal strategy!

You're math seems pretty dang close on the number of guesses it takes! I am taking the over though! :D

Your guess of 55 is CORRECT!!! Congratulations!!!

This is fun. Too bad I was late :/
