A strange little side quest
A small trivia drop for Rotate WebGL: The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. The broader history adds one more wrinkle. Computer Space reached arcades in 1971 and became one of the earliest commercial electronic arcade games, even though its controls proved demanding for many players. That long chain of experiments is part of why puzzles still feels fresh when a game finds the right twist.
