A strange little side quest
If Vikings sends you down a curiosity rabbit hole, start here. The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. That is only half the story. Boxing was part of the ancient Olympic Games by 688 BC, long before gloves, weight classes, or timed rounds existed in anything like their modern form. That long chain of experiments is part of why puzzles still feels fresh when a game finds the right twist.
