A strange little side quest
Put Castle Story next to the history of puzzles and a few unexpected connections appear. Arthur Wynne published a diamond-shaped 'Word-Cross' in the New York World on December 21, 1913; the name later shifted to 'Cross-Word' and then 'crossword'. A second detail makes the picture even better: Atari's Gran Trak 10 from 1974 is recognized as the first arcade racing video game. It is a good reminder that simple game mechanics can carry a surprising amount of history.
