They say the site provides a protected environment in which the kids can browse the Web. They also have more than 500 Java enhanced games online, as well as 2 multi-player games. These lead to different areas of the site with lots of activities.
Several features show how in-depth the site really is.
Parents and Teachers have a special section, where many activities are geared toward group fun and learning.
