7 Little Words — that’s its icon to the left — is a lovely little diversion, challenging enough to provide at least slight difficulty here and there, easy enough to solve in a minute or two. (You can make things more difficult by removing the number-of-letters hint for each word.) The daily puzzle is free online or as a mobile app. Extra puzzles for the mobile app are fifty for 99¢. Clues in the for-sale puzzles offer flashes of crossword-style wit. “Nice chap, perhaps”: FRENCHMAN.
