ClubTuki

The site's interactive games are clever and fun to play -- creatures in a memory game make a face when you click on them, and cheers ring out when you pick the right letter in a word game. The kid-friendly videos are also entertaining and will help teach simple lessons about subjects like finance -- or will just make users laugh.

But ClubTuki has some drawbacks: Most of the videos were posted by just one person, and only a few have been commented on -- the site could definitely benefit from more user activity. And while it's a neat idea to teach kids about saving and spending by placing their Tuki Moola in a pretend bank account, Primo members are the only ones who'll get the full benefit of the lesson. You have to be a paid subscriber to place bids on the site's auctions; if you're not, there isn't really anything to spend money on -- and you probably won't care about tracking your virtual cash. However, there's plenty of good, clean fun to be had at ClubTuki without paying the membership fee -- and that's great news.
