Today is the 100th anniversary of the crossword puzzle. Invented by British journalist Arthur Wynne and first published in the New York World on December 21, 1913. To celebrate the milestone, today’s Google Doodle is an interactive crossword, replete with a newspaper look and feel. When you complete the puzzle, a screen pops up with the answers along with your time.

The Washington Post has an interesting article about the “making of” this Google Doodle that almost wasn’t.
