Guess The Number

Guess The Number is a simple puzzle game where you must guess the hidden number.
Each level can be defeated within 10 attempts by guessing the correct number within a range (ie 1 to 100).
Each guess attempt results in 'too low' (guess was below hidden number) or 'too high' (guess was above hidden number).
The most common strategy to win is to divide the range in 2 each time so you can use a process of elimination where half the numbers are out of range with each guess. This can make guessing the correct number much easier.


Example guesses for hidden number '82':
50 = too low
75 = too low
87 = too high
81 = too low
84 = too high
83 = too high
82 = Winner!

There are 3 difficulty choices:
(easy: 1-50)
(medium: 1-100)
(hard: 1-500)
