Today I found out about a cool and challenging website thanks to Library Stuff’s blog post: Are You Smart Enough?. It features a 3,000-question puzzle and all the questions are riddles of some kind. So far, they don’t look like they’re technology related or anything, like SOME of these sites use. They’re mostly just riddles and word puzzles. But using Google may still help occasionally. :-)

One cool thing is that you can enter your latest correct answer on ANY screen and jump to your next one. So no remembering the path and all your answers–just your most recent one.

But with three THOUSAND questions, it will probably take a LONG time to work your way through it all. By the way, there are, in fact, prizes available along the way. Like 100 of them! So get going! :-)
