Puzzle master Will Shortz offers a quiz and has a challenge for everyone at home.
Challenge from January 14: The special two-week challenge launched on Jan. 7 continues: The object is to arrange 16 different letters of the alphabet into a 4-by-4 square, so four common, uncapitalized words read across and four common, uncapitalized words read down.
To start, the second word across is ruly. This is the only slightly unusual word in the square. Every other word in it is one any school child would know. Can you do it?
This challenge will close at 3 p.m. on Thursday, Jan. 18
