Quizzio is a PHP based application through which you can create a quizing website. Users can play and create quizzes. They can embed quizzes to their websites. By purchasing credits they can make a quiz exclusively embedded to single domain.
Introducing Premium Quizzes
Normally Quizzio gives users the option of embeding quizzes to their website. A user creates a quiz but there can be multiple users embedding that quiz to their websites, in addition to the quiz being available on Quizzio based website.
But by purchasing credits the user can make his created quiz “private”. The premium quiz can be embedded to a single domain of his choice. No user can embed that quiz, nor will the quiz be available on Quizzio based website.
The catch is that every time the quiz is played on the user website(where he embedded the quiz), 1 credit is consumed. So the user has to make sure that there are enough credits in his account so that the quiz remain premium.
