What Is This Game?
Number guessing is the classic binary-search brain teaser: a random number is hidden inside a range, you guess, and the game tells you whether the real number is higher or lower. The challenge is narrowing it down in as few guesses as possible.
How to Play
- Pick a range (1–50, 1–100, 1–500 or 1–1000).
- Type a guess and press Enter or click Guess.
- Read the hint — too low or too high — and adjust.
- Find the number and see your attempt count. Start a new round anytime.
Tips
- Always guess the midpoint of the remaining range — it guarantees the fewest guesses (about 7 for 1–100).
- Track the live range the game shows you after each hint.
- Never guess the same number twice.
