A strange little side quest
There is a neat bit of history hiding behind the kind of play you find in Bubble Mania. Chess changed dramatically in Europe during the 15th and 16th centuries when the queen became the board's most powerful piece. And then there is this: 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.
