In looking for information about puzzles for our gender webquest, I happened upon the Puzzles.com site and proceeded to play a few of these puzzles including The Marbles and Rows Puzzle and the Elephant SpinOut Puzzle. If you want a distraction from doing homework (e.g., an alternative to cleaning your house), try one of these. This site also had a link to the Puzzle Museum where I found some useful information on classes of puzzles.

(I also had fun trying to "Make a Masterpiece" referred to on 12/4 by Dan McDowell.)
