100th Anniversary of the Crossword Puzzle

In celebration of what Google and others consider the 100th anniversary of the modern version of the crossword puzzle, Google has created an online, interactive crossword puzzle.

To begin, click the circle with the arrow in it. The window will expand into an actual crossword puzzle. For items that have only one direction (across or down), click the numbered square to select it. For items that have two directions (across and down), click the numbered square once for across and twice for down. Either way, the list on the right will jump to and highlight the selected clue. Then just type in the, hopefully, correct answer.
