Star Castle

Gameplay

The player's ship orbits around three concentric rings of rotating shields protecting a central cannon. The cannon periodically fires homing projectiles at the player. The player must blast gaps in each ring to expose the cannon and destroy it. Rings slowly regenerate, creating pressure to work quickly. Small mines are also released to threaten the player.

Historical Significance

Star Castle was one of Cinematronics' most commercially successful titles. Its elegant design — concentric defensive rings around a central threat — created a tense, strategic experience perfectly suited to the vector display's strength with circular geometry. The game directly inspired Yars' Revenge (1982) for the Atari 2600, as programmer Howard Scott Warshaw was tasked with creating a home version of Star Castle but transformed the concept into an original game.

Fun Facts & Legacy

The three shield rings rotated at different speeds and directions, creating constantly shifting gaps that skilled players could exploit. The game's design is a masterclass in simplicity — the entire concept can be explained in one sentence, yet the gameplay has enormous depth. Star Castle cabinets are highly sought by collectors.
