A strange little side quest
The Visitor has plenty of company in a long tradition of players chasing timing, patterns and better decisions. 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. That long chain of experiments is part of why puzzles still feels fresh when a game finds the right twist.
