A strange little side quest
A small trivia drop for Trollface Quest: The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. The same trail leads to another fact: Pong was field-tested in California bars in 1972 and helped launch the modern arcade-game era. So a round of Trollface Quest is not just a quick distraction; it is a tiny stop on a much longer puzzles timeline.
