A strange little side quest
A small trivia drop for Bouncy Egg: The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. The timeline takes another interesting turn: Nintendo's Donkey Kong arrived in 1981 and introduced the character first known as Jumpman, who later became Mario. So a round of Bouncy Egg is not just a quick distraction; it is a tiny stop on a much longer puzzles timeline.
