A strange little side quest
A quick detour while Cyber Cat Assembly waits for your next move: The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. That is only half the story. Boxing was part of the ancient Olympic Games by 688 BC, long before gloves, weight classes, or timed rounds existed in anything like their modern form. That gives Cyber Cat Assembly a little more company than it first appears to have.
