Poptropica is an educational website featuring games, stories and exploration that helps to teach literacy and problem solving skills. The website is completely secure and is intended for kids up to age 15. No personally identifiable information is provided from the kids, and the website is moderated for extra security. A limited version of the website is available for free; however, to take full advantage of everything Poptropica has to offer, a paid membership is required.
Full membership includes: early access to new islands, unlimited costumes and super-powers, a "costume closet" where you can save up to 30 custom creations and a photo album in which to save your adventures.
Membership is available in one-month, three-month, and six-month terms which automatically renews at the end of the term, as of 2015. The cost is $3.95 for one month, $10.95 for three months and $19.95 for six months. The longer the term you choose, the more value you get. A six-month membership works out to $3.32 per month, versus $3.95 when paying month-to-month.
