A strange little side quest
Before the next round of Classic Lines 10x10, here is a piece of the bigger picture. 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'. The broader history adds one more wrinkle. Midway's Gun Fight from 1975 was the first arcade video game to use a microprocessor. That long chain of experiments is part of why puzzles still feels fresh when a game finds the right twist.
