3D Pinball: Space Cadet Cheats
There are two ways to refuel your ship. The first is to pass the ball through the slot above the left hand flipper (under the launch ramp hole). The easiest way to do this, obviously, is to go through the launch ramp. For the second method, there is a bridge where the launch ramp is located. It has colored lights through it. Shoot the ball all the way through and spin the flag, and your ship will be refueled.
