While kids can enter this world for free, they don't get the benefit of Elf Island's "Gaming for Good" without becoming a paying member. Only paying members can go on "Good Quests." Membership starts at $5.95 for a month, $29.95 for 6 months, or $57.95 for a year. Since the game is actually contributing money to the non-profit partners to do good in the real world, this membership cost makes sense. Plus this way, Elf Island is a site that has no advertising.
