Frequently Asked Questions
What is the best strategy for guessing the number?
The best strategy is called binary search: always guess the middle of the remaining range. For example, if the range is 1-100, guess 50 first. If the answer is higher, guess 75 next (the middle of 50-100). This way, you can find any number in 1-100 within 7 guesses.
What does the closeness meter show?
The closeness meter fills up as your guess gets closer to the secret number. A nearly full bar means you are very close. The bar also changes color from blue (far away) through yellow (getting warmer) to green (very close), giving you a visual sense of how near you are.
What age is this game for?
Guess the Number is fun for all ages. Easy mode (1-10) works well for kids ages 4-6 who are learning number concepts. Medium (1-50) and Hard (1-100) are great for elementary school kids practicing number sense and logical thinking. Expert mode (1-500) challenges older kids and adults.
How does this game help with math skills?
Guess the Number develops number sense, estimation, logical reasoning, and strategic thinking. Kids learn about number order, greater than and less than concepts, and narrowing down a range. The binary search strategy teaches an important computer science concept in a fun, intuitive way.
Are my scores saved?
Yes! Your stats (games played, wins, best score, best streak, and average guesses) are saved in your browser. They will persist as long as you use the same browser and do not clear your browsing data. Each difficulty level tracks its own best score.
What is a good score?
A perfect game on Easy is guessing in 1-2 tries. For Medium, 4-5 guesses is excellent. For Hard, anything under 7 is great (mathematically, 7 is the most you should ever need with the best strategy). For Expert, 9 or fewer guesses is impressive.
