Your objective is to recover the throne of the Inkaplonka King. To reach this treasure you must descend through five tunnels and brave the different hazards on each level. These include moving mines, flying shells, dangerous ground, hovering discs and boulders. Using the joystick in various ways according to which level you are on, the throne must be reached in the best possible time.

The screen display shows all five levels, the time, best time and number of lives remaining - from a maximum of five. Access to each level is obtained by descending a ladder.

Although instructions are provided on screen, because they are loaded separately you need to make notes of how to use the joystick on each level before actually starting. Written instructions on the cassette insert would be more helpful.

Any enjoyment of the game itself is spoilt by various bugs inherent in the program. I failed to get any further than level three, being prevented not only by bad luck but by two "Bad Value"s and a "Syntax Error"!
