A strange little side quest
A small trivia drop for Mahjong Cards: The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. That is only half the story. 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 is the kind of background detail that makes another attempt at Mahjong Cards feel a bit more connected to the history of play.
