A strange little side quest
A quick detour while Screw Sort Puzzle: Pin Jam 3D waits for your next move: The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. A second detail makes the picture even better: Street Fighter II, released in 1991, turned head-to-head arcade fighting into a worldwide phenomenon and helped define the modern fighting-game genre. That is the kind of background detail that makes another attempt at Screw Sort Puzzle: Pin Jam 3D feel a bit more connected to the history of play.
