The crossword puzzle turns 100 Today.
The game was invented by Arthur Wynne to fill some space in the Christmas addition of the New York World newspaper on Dec. 21, 1913.
The puzzle was originally named ‘Word Cross’ and was shaped like a diamond.
It was an overnight success and other newspapers began copying what soon was called the crossword.
One hundred years later, newspapers have declined but crosswords can be found all over the internet.
About 50 million people do crosswords occasionally, according to the 2011 book “From Square One.”
