The New York Times Toughest Crossword Puzzles series has always been incredibly popular with the crossword set, but there has never been an omnibus compilation -- until now. The MegaOmnibus contains a whopping 300 New York Times crosswords, all culled from Saturday, the most challenging day of the week. At a minuscule price per cranium-cracking puzzle, this book of super stumpers is also a super value.
