About Number Guess
Number Guess hides a number between 1 and 100. Each guess gets a 'higher' or 'lower' hint. Crack it in as few tries as possible.
How to Play
- Type a number from 1 to 100 and submit
- Get a hint: too low or too high
- Use the hints to narrow your range
- Find the number in 7 guesses or fewer
Tips & Strategy
- Use binary search: always guess the middle of your range
- Start at 50, then 25 or 75 based on the hint
- You can theoretically find any number in 7 guesses or fewer
- Don't guess randomly — track your range
