A strange little side quest
Here is a rabbit hole for the next loading screen in Animal Kingdom Mahjong: The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. 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. That gives Animal Kingdom Mahjong a little more company than it first appears to have.
