Every 4 galactic-years, alien athletes from every inhabited planet in the
galaxy gather to compete in the _Purple Saturn Day_ games. Four interplanetary
events await the player: Pilot a ship through time and space, race around the
rings of Saturn, solve a fast-moving electronic puzzle and navigate a
futuristic obstacle course.

Although not an official entry in the series, this game is in the same vein as
Epyx’s popular Games “series” titles.
