A strange little side quest
Even a quick game like Mahjong Chains sits on top of decades — and sometimes centuries — of ideas. The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. That is only half the story. Atari's Gran Trak 10 from 1974 is recognized as the first arcade racing video game. It is a good reminder that simple game mechanics can carry a surprising amount of history.
