Number Guess โ€” Logic Puzzle Game in Your Browser

Number Guess challenges you to find a secret number hidden somewhere between 1 and 100, and you have exactly 10 attempts to do it. After each guess the game tells you whether the target is higher or lower than what you entered, so every failed attempt still gives you useful information to narrow the range. The game ends when you either land on the correct number or exhaust all ten guesses โ€” at which point the target is revealed.

Your best score is recorded across rounds within the same session: it shows the fewest attempts you have ever needed to crack a round. A guess history panel below the controls shows every number you have submitted so far, making it easy to keep track of the range you have already ruled out. There is no time limit, so you can think carefully before committing to each guess. When a round ends, click 'New Game' to get a fresh hidden number and try to improve your best.

Yes, 100% free. No payment, no subscription, and no locked features of any kind.

No. The game loads in your browser instantly โ€” no account, no download, and no plugin required.

What is the optimal strategy to guess in the fewest attempts?
Use binary search: always guess the midpoint of your current possible range. Start at 50. If told 'too low', your new range is 51-100, so guess 75 next. If told 'too high', guess 25. Repeating this halving approach guarantees you find any number between 1 and 100 in at most 7 attempts.
