A strange little side quest
The rules may be simple on screen, but the backstory around Neon Flip is anything but tiny. 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'. And the history keeps stacking up: Midway's Gun Fight from 1975 was the first arcade video game to use a microprocessor. It is a good reminder that simple game mechanics can carry a surprising amount of history.
