A strange little side quest
If Screw Master sends you down a curiosity rabbit hole, start here. The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. It also connects to a different milestone: Space Invaders, released in 1978, helped push video games into mainstream popular culture. That is the kind of background detail that makes another attempt at Screw Master feel a bit more connected to the history of play.
