Warm/Cool Number Guessing (Posted on 2013-09-30) Difficulty: 3 of 5
Here's another number guessing game:

I randomly pick a number from 1 to 1000. After you make your first guess at the number I will only tell you whether it is warmer (closer) or cooler (farther) or neither, to a 'zeroth guess' of 500.

For successive guesses I will tell your warmer, colder, neither, to the closest of the previous guesses.

What is the minimum number of guesses that would guarantee that you win with an optimal strategy?

What is this strategy?

Question How does the game end? | Comment 4 of 6 |

If my first guess is the number you are thinking of, then is the game won, or do you just tell me "warmer"?
