On the 9th of February 1925, the first Estonian language crossword puzzle was printed in the Esmaspäev newspaper. A prize of 3,000 marks was on offer to the first person who could solve it. Not all crossword prizes were monetary however, they also included books, trips, and clothes pins. Crossword puzzles remain popular to this day.
The world's first crossword puzzle was published on 21 December 1913 in the fun pages of the New York World Newspaper. It was invented by British journalist Arthur Wynne who emigrated to the United States in the late 1890's.
