From the Digger Manual: DIGGER is a new Gremlin/SEGA game that requires you to dig strategically placed holes within a maze format so you can capture and fill in over the invading creatures before they can attack and destroy your man. You maneuver your man around the maze with a four-directional joystick. Two push-button controls are used for your shoveling action: one, for the DIG function and another for the FILL function. The maze format changes with every round played. DIGGER is a Gremlin Multi -Phase game that becomes increasingly challenging as your skills improve, as you will see. The creatures are confined behind a wall. In the first of three rounds of game play, four creatures are let out of the holding area through a gate. You must conquer these four before advancing to the next round, where you face six creatures. Your third round has you battling eight creatures. This process is repeated and the point value increased with each three-round victory. Also, the creatures' speed increases each round. Any contact at all with the creatures will be fatal to your man. While you are busy digging holes and entrapping creatures, the rest are behind the retaining wall scurrying back and forth. After about three minutes, the gates at each end will open and all of. the remaining creatures will stream into the play area at once. However, a skillful player will conquer all of the creatures of each round and the gate will not be a threat. A DOUBLE SCORE BONUS is awarded If you capture and fill in over the RED creature before any of the GREEEN ones. But, this must be the FIRST creature defeated, or the RED creature becomes GREEN and no bonus is awarded. The point value per creature increases with each three-round phase. The first phase awards 300 points per creature, decreasing to 100 points if not filled over promptly. The second phase awards 500 points per creature, decreasing to 300. And, the third phase awards 700 points, decreasing to 500 points. A 1000 POINT BONUS...
