I can no longer download Houston Chronicle puzzles!
Unfortunately the Houston Chronicle crossword distributor, CrosSynergy Syndicate, has requested that we no longer automatically download them in the app, but they are still available daily at http://www.chron.com/apps/games/xword/puzzles/ and can be imported via the Puzzle Calendar (the + button on Puzzle List screen) > Other.
If you're looking for a daily puzzle to replace the Houston Chronicle, we suggest either the Newsday puzzle or the Tulsa World. Our apologies for the inconvenience!
