A strange little side quest
Between one round of Room Escape: Bedroom and the next, this is worth knowing: The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. The broader history adds one more wrinkle. Pong was field-tested in California bars in 1972 and helped launch the modern arcade-game era. That is the kind of background detail that makes another attempt at Room Escape: Bedroom feel a bit more connected to the history of play.
