The Play:
Your aim is to collect precious gold and emeralds buried deep in subterranean levels of an old abandoned mine. With your motorized Digger Mobile, you tunnel out new shafts, scoop up emeralds and race ahead while dodging falling bags of gold and avoiding wide-eyed Nobbins hot on your trail.
    Valuable gold nuggets are stashed in heavy bags throughout the mine. You can push the bags down open shafts to break them open and expose the glimmering gold inside. This is your chance to scoop up the riches before the Nobbins beat you to it.
    To advance to a more challenging level with more Nobbins, Hobbins and gems, you must scoop up all the emeralds of destroy all the Nobbins in the current level.

Eliminating Nobbins:
You'll need skill and quick wits to avoid and destroy the wide-eyed Nobbins chasing you through the open shafts. Nobbins often grow impatient and turn into angry foot-stomping Hobbins who burrow through the mine to destroy your Digger Mobile.
    Nobbins are very delicate creatures. By pushing the heavy bags of gold down the long shafts, the Nobbins are crushed under the weight of the bursting bag. Don't forget to scoop up the gold when the bag breaks!
    Another defense against Hobbins and Nobbins are the bouncing fireballs on the roof of your Digger Mobile. Press Function Key F1 to throw the fireball, but be careful not to waste your shot since it takes time to regenerate another fireball.

Bonus Round:
After all the Nobbins have entered the abandoned mine, cherries appear in the upper right corner. Scooping up the cherries starts a special chase where you pursue the Nobbins and Hobbins for bonus points. Although your fireballs and falling bags still destroy the frightened creatures, you only win bonus points by colliding with them.

Loading Digger:
Place your Digger diskette in the left disk drive of your IBM PC and turn your computer on. When the title page appears on your display, you are ready to select one or two player game option.

The title page shows the One Player option. If Two Players want to join in the fun, press the ESC key to the left of the keyboard. When the title page shows the correct option, you are ready to select joystick or keyboard control.

Joystick Control:
Centre your joystick and press button #1. This will start the game using joystick control.
    Use the joystick to maneuvre your Digger Mobile through the mining site following old mining shafts and tunnelling new paths.
    Press button #1 to throw fireballs at the approaching Nobbins and Hobbins.

Keyboard Control:

    Press Function Key F1 to throw fireballs at the approaching Nobbins and Hobbins.

Your score depends on the amount of emeralds and gold you collect, as well as the number of Hobbins and Nobbins you destroy. If you collect 8 emeralds in a row, you get 250 bonus points.

     Nobbins ................... 250
     Hobbins ................... 250
     Emeralds ..................  25
     Gold Nuggets .............. 500

Bonus points:
     8 Emeralds in a row ....... 250
