Logic Problems

I used to love doing those logic problems where you use a huge insane looking grid to figure out which people lived in what color house and in what order on the street, etc. Someone at Babble pointed this site out to me:

It's just like the paper and pencil kind, except it's online. You can check the boxes right on your screen, and get a confirmation when you've solved the entire puzzle correctly. New puzzles are posted monthly. Enjoy!
