I'm rolling out a new feature for some of my Google Maps based quizzes for Premium Members - the option to show/hide the markers during the quiz. This gives you the option of hiding all markers except the guesses you have successfully made to add a bit of challenge to the quiz.
Premium members will now start seeing the 'Show/Hide Markers' option on quizzes such as US Largest Cities
