A strange little side quest
If Block Blaster sends you down a curiosity rabbit hole, start here. The first crossword puzzle book appeared in 1924 in a cautious initial printing of 3,600 copies, complete with a free pencil. The timeline takes another interesting turn: Pac-Man went on sale in 1980, and its creator Toru Iwatani famously linked the character's shape to a pizza with a slice missing. That gives Block Blaster a little more company than it first appears to have.
