A strange little side quest
The rules may be simple on screen, but the backstory around Save the Dog is anything but tiny. The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. That is only half the story. Space Invaders, released in 1978, helped push video games into mainstream popular culture. So a round of Save the Dog is not just a quick distraction; it is a tiny stop on a much longer puzzles timeline.
