A strange little side quest
Waku Waku TD belongs to a much longer story of play than a browser tab might suggest. Chess changed dramatically in Europe during the 15th and 16th centuries when the queen became the board's most powerful piece. The same trail leads to another fact: 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. Not bad for a few facts hiding behind a Play button.
