This is a very popular game in japan, and yes if the answer is wrong they lose, if right they are asked if the want to continue, usually this means a bigger payoff.

Might consider adding:

if ($guess was right)
{
  continue();
}
else
{
  exit;
}

sub continue()
{
   ask user to enter y or n
   read in answer
   chomp answer
   lowercase input #or uppercase I just like lower
   default input to n unless it is y or n  #or y if you were a real hu
+ssler
   return answer
}

Yes my pseudo code has code in it, just the way I code :). Didn't read merlyn post before posting, so this was not meant as an opinion. My opinion on that is merely that this post asked for pseudo code so I gave pseudo code. Thought this was both because I really don't know who to do this, and I'm just weird.
