Little Rockford's job is to dig through 16 different playfields of soft, boulder-strewn earth filled with the glittering diamonds. Any time he dislodges a boulder (by either moving or digging directly beneath it), the rock falls until it reaches solid ground. Rockford can outrun any falling boulder - as long as he doesn't hesitate. If he's caught by a rock, or even by a jewel dislodged from its place, he loses a turn. It's also possible to be trapped on all sides by unmovable rocks. When this happens, press the ESCAPE key to reset the screen.
