This looks suspiciously like an answer for an exercise in my Learning Perl. {grin} Good job.

To turn this into a CGI, you have to maintain state between hits. I suggest a server-side database, although an appropriately encrypted hidden field with the right answer and number of guesses so far would also work.

I wrote an article about how to make online quizzes "cheat-proof". Check it out.
