The crossword puzzle is a pencil-and-paper game in which the solver fills in words on a pattern of blank squares separated by solid blocks. The crossword, as its name indicates, uses different, interlocking words across and down and is provided with two sets of numbered definitions, one for those words to be written across the pattern and one for those to be written down. Many blanks are numbered and each number matches a definition bearing the same number either across or down or both. The letters of the word that fits the definition are put in the blank squares. The filled-in puzzle is usually printed later so that each person can check his accuracy and learn the words she has been unable to identify. Have you ever wondered how the crossword puzzle came into existence? The first crossword puzzle appeared on December 21, 1913. Arthur Wynne created it for the New York World newspaper.
