Patrick Blindauers Safe Sextet is a 21x21 puzzle, rated 3/5 difficulty.
And it has a contest-type thing! Send us (at firstname.lastname@example.org) a picture of something that's visibly 72-Across in your life, and you'll be entered to win one of two prizes -- if you're coming to Lollapuzzoola 10 next month, a copy of Doug Petersons Easy as ABC Crosswords, plus a silly hat to wear at the tournament (if you want), and if you're not coming, a free 3-month AVCX subscription extension. So be sure to let us know, in your contest entry email, if you'll be at the tournament, which Patrick co-organizes.
Oh, and speaking of that: Lollapuzzoola 10 is happening in New York City on Saturday, August 19. If you didn't already sign up for the live show (it's sold out), you can always play from home. The At-Home Division features all seven puzzles from the tournament plus (optional) instructions for tracking and submitting your scores. Read more at www.bemoresmarter.com.
