A strange little side quest
The mechanics around Super Stacker have roots that stretch far beyond modern browsers. 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'. That is only half the story. Midway's Gun Fight from 1975 was the first arcade video game to use a microprocessor. Not bad for a few facts hiding behind a Play button.
