How Many Guesses?
Sponsored by MindSumo

I am thinking of a number between 1-100 (exclusive) and want you to guess my number. For each guess, I will tell you whether you're too high, too low, or guessed correctly. What is the fewest number of guesses you can make to guarantee that I will say your number is correct?

Difficulty: 9/10
