I know a lot of people who spend all Sunday doing brain teasers in the Times. Now that is dedication!

If you want to get a truly great assortment of brainteasers, you have to go to a good bookstore. There are plenty of online brainteasers, but if you are a big fan you probably need to just bite the bullet and buy a book. After all, it is nice to have a whole book filled with logic puzzles so that you can go through them, page after page at your leisure. The way that I do it is to download some free puzzles on the Internet to see which ones I like. Then, when I find a style that fits me, I buy.
