I've been waiting a few weeks to post on this, but the site links haven't been working. Checked last night, and LO, they are good again.
Intelligence Test part 1
Intelligence Test part 2
Intelligence Test part 3
Intelligence Test part 4
These links will take you to 4 different "intelligence tests." I'm not sure how accurate they are in determining smarts, but they're a lot of fun. All are in this format:
24 H in a D = 24 hours in a day
Where you have to fill in the right side.
I've gone through the first three of these tests already, and haven't had one where I got all the answers myself. In fact, I don't think I've gotten more than 60 - 70 percent on my own. And that's part of what makes these so fun, because they're great to brainstorm over -- with coworkers, family, friends, etc.
Update: The links are working again... for now!
