The New York Times note:
All the puzzles this week, from Monday to Saturday, have been created by one person, Patrick Blindauer. Keep your solutions handy, because the Saturday puzzle conceals a meta-challenge involving the solution grids of all six. When you have the answer to the meta-challenge, send it to email@example.com. Twenty correct solvers, chosen at random, whose entries are received by 6:00 p.m. E.T. Sunday, Oct. 26, 2014, will win one-year online subscriptions to the New York Times crossword. Only one entry per person, please. The answer and winners’ names will appear on Friday, Oct. 31, at www.nytimes.com/wordplay.
