A strange little side quest
The rules may be simple on screen, but the backstory around Color Fan: Color By Number is anything but tiny. The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. A second detail makes the picture even better: Women competed in Olympic archery as early as 1904, making it one of the early Olympic sports to include women. It is a good reminder that simple game mechanics can carry a surprising amount of history.
