You are a character digging around for gems and other trophies. Tha game has a strong puzzle element, in that you've got to work out how to get the gems without getting squashed by rocks and bounders which hang precariously abouve you, and should you knock away the supporting earth, the rocks come tumbling down. There are nine game scenarios with five levels to each and the graphics, objects to collect and nasties change with each scenario.
