Gyroscope is an action video game published by Melbourne House in 1985 for the Acorn Electron, Amstrad CPC, BBC Micro, Commodore 64, and ZX Spectrum.
Melbourne House would go on to publish the official ports of Marble Madness for the ZX Spectrum and Amstrad CPC, but these were not based on Gyrosope.
The player must guide the gyroscope from the top of the course to the bottom within an allotted time limit.
Hazards on the course include potholes, aliens and glass slopes which cause the gyroscope to spin in random directions.
Electron User gave it a score of 6/10, again praising the graphics, but complaining about a number of bugs spoiling "what could be a very good game".
