A strange little side quest
A small trivia drop for Card Golf Solitaire: The first crossword puzzle book appeared in 1924 in a cautious initial printing of 3,600 copies, complete with a free pencil. The same trail leads to another fact: Pong was field-tested in California bars in 1972 and helped launch the modern arcade-game era. The screen is modern; the urge to test skill, pattern and timing definitely is not.
