There is no minimum age requirement to play "Herotopia" online. The game requires children to read and is geared for those age 6 and older, but children of any age can play with the assistance of a parent.
"Herotopia" is an award-winning educational game that allows users to create a superhero avatar and learn about geography, math, reading and foreign language. Kids are encouraged to practice social responsibility through battling bullies to create a "Bully-Free School," and to employ global heroship with a focus on embracing cultural diversity and protecting endangered species. Parents must help their children sign up for a membership, which costs $5.95 per month as of 2015.
