Code Monster is the most basic and, according to the website, is suitable for preteens and older. Next, Code Maven is slightly more advanced, though the format is the same. This is suitable for teens and adults. Finally, Game Maven offers the opportunity to explore more advanced JS concepts specifically for creating games, and is also suitable for teens and adults.
