in reply to setup of a small perl game

Sure, in pseudocode (or wishfulthinking code) it's a piece cake: 

print_greeting();
reset_score();

OUTER:
while ( 1 ) {
  my $current_question = ask_next_question();
 
  my $attempts = 0;
  while ( $attempts++ < $MAX_ATTEMPTS ) {
    my $answer = get_answer();
    last OUTER if $answer eq 'q';
    last if check_answer( $current_question, $answer );
    print_sorry_try_again();
  }

  if ($attempts < $MAX_ATTEMPTS ) {
    print_congratulations();
    update_score( 1 );
  }
  else {
    explain_correct_answer( $current_question );
    update_score( 0 );
  }
}

print_score();
print_good_bye();

    Thanks for your help! I tried using your method and got the following. It sorta works as it either says you got it right or wrong. However I don't know how to make it go back to the beginning if they got it right. It just sort of sits there until you make 4 more wrong guesses after you make it right.

    What do I need to do?

    while (1)
{
   
   ###########
   # Heart of the game- Choose and scramble a word
   ###########
   my $word = $words[rand @words];

   my @scramble = split(//, $word);

   @scramble = sort { (-1,1)[rand 2] } @scramble;

   print "\n\nGuess the scrambled word: ";
   foreach (@scramble) {print $_};
   print "\n\n";


   my $attempts = 0;

   while ($attempts++ < $max_attempts)
   {

      #####
      # Take their guess
      #####
      my $guess = <STDIN>;
      chomp($guess);

      if ($guess ne "$word")
      {
         print "$guess is incorrect.\n";
         $attempts++;
      }
      else
      {
        print "Congratulations!  The scrambled word was $word.\n\n";
      }
   }
   
}

      The quick fix would be to insert a last after the "Congratulations" line, like this: 

        {
    print "Congratulations!  The scrambled word was $word.\n\n";
    last;
  }

      but IMHO I would advice you to follow the structure I gave you more closely; I think you will find that your script is clearer, and more easily modified and debugged if you actually implement functions like check_answer(), etc., that I used in the "wishfulthinking code". The more your code looks like pseudocode, the clearer it will be.

        last; did fix it, thanks!

        You are probably right, functions might be easier to debug later. By functions do you mean sub routines? I could probably do that. I'm not too versed with self-made functions, however.
