A strange little side quest
A small trivia drop for Google Block Breaker: The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. The broader history adds one more wrinkle. Pac-Man went on sale in 1980, and its creator Toru Iwatani famously linked the character's shape to a pizza with a slice missing. The screen is modern; the urge to test skill, pattern and timing definitely is not.
