The object of this game is to mine gold, diamonds and coal. To score on the first two screens (gold and diamond) the miner must first fill his barrow by completely mining one level and return with his load to the bank at the top right hand side of the screen. When these two screens are completed the furnace on the left hand side of the screen will be low and must be filled with coal on the third screen.

When the miner descends below the first mining level the troglodyte will attempt to destroy him, but the troglodyte itself can be destroyed if it is lured out of the top of the mine. Unfortunately it will be replaced by another on the lowest level.

The miner can move between levels by either using the constantly moving lift or by digging between levels and automatically leaving a ladder. Only one ladder can be used at each level and although the troglodyte cannot use the ladders neither can the miner take his barrow up or down them.

Apart from being caught by the troglodyte the miner will also be destroyed if he falls down the lift shaft or furnace. The barrow with its load will also be destroyed by falling down the lift shaft but will be replaced by a new empty barrow at the bank. There is an unlimited supply of barrows but only three miners.

The four cursor control keys are used to move the miner around the screen.
