Shikaku Puzzle

A strange little side quest

A little context makes Shikaku Puzzle more fun to place on the gaming map. The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. The broader history adds one more wrinkle. Spacewar! appeared on MIT's PDP-1 in 1962 and became one of the earliest influential computer games shared among programmers. That history is one reason familiar mechanics can still feel new when they are recombined well.
