Jumping Jack is the exciting arcade game of luck and skill. Using the keys, the goal is to reach the top of the screen. Each screen consists of 6 floors, and Jack has to jump throught the (moving) holes in these floors to progress. If Jack falls down one of these holes, he is momentarily stunned, and loses a life if he falls through the bottom floor. Things are made more difficult on later levels with the addition of nasties that walk along the floors, and also need avoiding. The number of nasties present depends on the level Jack is on.
