What are some good puzzle/ thinking games that I can play online?

I want to play a game similar to one i played a few years ago where you have to figure out the password to the next level...I don't quite remember anymore than that. I would prefer them to be unique games that I won't get bored with easily. Thank you.What are some good puzzle/ thinking games that I can play online?

This might not fit into your preferences, but I figured it wouldn't hurt to post.



http://www.neopets.com has a lot of thinking games. it's a family oriented site where you own virtual pets, and they have some thinking games similar to figuring out a 'password'. Only you have to figure out the particular color combo to advance to the next level.
