Not raptor related, but there are many crossword puzzle links to help keep the mind sharp (or at least functioning.) We like The Detroit News (

http://puzzles.usatoday.com/index.html) puzzles because they are easy to print and work off line. There is also a weekly Classic New York Times Crossword Puzzle (
