Number Quest

Guess a number between 1 and 30. Each wrong attempt costs a point, and the game remembers your best round until you reload.

What it does

A small JavaScript exercise built around the game loop: check a guess, update the score, end the round, and reset without reloading.

Keep score in JavaScript: The score and high score live in page-level variables. Replay resets the score but not the high score; no storage or server is involved.
Lock a finished round: After a win or loss, Check is disabled and the input becomes read-only until Try Again is pressed.

More on the implementation and challenges.

The Check button compares the entered value with the hidden number and responds with Too high, Too low, or Number is correct.

Each incorrect guess removes a point. Correct answers update the high score if the remaining score is better than the last successful round.

Try Again chooses a fresh number and restores the score, input and background. The current high score is retained in memory.

Problem: Continuing to guess after a win or a loss would change the completed round.

Solution: The script disables Check and makes the input read-only after success or after the score reaches zero.

Problem: Restarting should reset the round without wiping the best score from the current visit.

Solution: Try Again resets the target and current score, but leaves the high-score variable untouched. A full page reload resets it.
