Play the free online Guess the Number game. Guess a random number from 1 to 100, use higher/lower hints to narrow the range, and win in the fewest steps.
Current Range: 1 ~ 100
Guess History
No guesses yet.
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
The game selects a hidden integer from an inclusive range: both minimum and maximum can be answers. Enter a whole-number guess; the result says higher, lower, or correct. The starting range is 1 through 100, and the guess limit starts at 10; both range and attempt limit can be edited.
Each valid guess narrows what you know. If 1–100 and a guess of 60 returns lower, the answer must be 1–59. A guess of 30 that returns higher narrows it to 31–59. This is a reasoning game, not a daily puzzle or a number picker.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Set a minimum and larger maximum. Choose 1–50 attempts. Changing a range or attempt setting starts a fresh round.
Enter a whole number inside the inclusive bounds. Decimals, out-of-range values, and guesses already used in this round are rejected without consuming a turn.
For higher, eliminate the guessed number and everything below. For lower, eliminate the guess and everything above. Continue until correct or attempts run out.
Use the new-game control to choose a new hidden number for the current range and review the round history and best result.
With bounds 1 and 100, guess 50. If the clue is higher, guess 75 to divide the remaining 51–100 range again.
Use cases
See how the tool fits into real work and everyday tasks.
Use the changing interval to practice integer bounds and see how a clue changes the possible answers.
Take turns and discuss which values each hint rules out. The attempt limit keeps the round bounded.
Play with the default range or make it smaller for a faster challenge. A new round selects a new answer.
Q&A
Find concise answers to common questions and confusing cases.
Yes. Minimum and maximum are eligible answers and valid guesses.
No. Empty, non-integer, out-of-range, or repeated guesses are rejected and do not enter history.
Changing a bound or the attempt limit clears the round and selects a new answer if the minimum is below the maximum.
Notes
Review scope, result limitations, and important precautions before use.
The answer is randomly selected for play and clues apply only to the current round. A midpoint strategy narrows an integer interval efficiently, but no chosen attempt limit guarantees a win. This is entertainment and practice; a score does not measure general intelligence or predict performance elsewhere.
