The pizza story is only half true. This episode explores how 24-year-old Namco designer Toru Iwatani shaped Pac-Man from the Japanese kanji for mouth and the onomatopoeia paku-paku, and why he deliberately rejected the smoke-filled, male-dominated, Space Invaders-era arcade of 1979 to build a colorful, nonviolent game that would draw in women and couples. We cover the unusually long one-year-and-five-month development with a nine-person team, the Popeye-inspired power pellet, the slot-machine fruit bonuses, and the new RGB display technology that replaced cellophane taped to monochrome monitors.

We also dig into Iwatani’s fight with Namco president Masaya Nakamura, who wanted all four ghosts colored red, and the deterministic AI that gives Blinky, Pinky, Inky, and Clyde distinct chase, ambush, flank, and retreat behaviors. Then comes the rocky Shibuya location test, the 1980 US trade show where buyers bet on Rally-X instead, Atari passing on distribution, Midway’s vandalism-driven rename from Puck Man to Pac-Man, one billion dollars in quarters in a single year, 30 million American players by 1982, Pac-Man Fever, a Saturday morning cartoon, a place in the Museum of Modern Art, and Iwatani’s later work on Pac-Land, Pac-Mania, and Championship Edition.
