This set of Pang again points to the common practice of releasing multiple revisions of arcade games, often to address bugs or optimize the game for specific hardware. The differences between this set and others might be minimal, but the variations indicate the level of refinement and adaptation common in the arcade game development process.  Despite the set differences, the bubble-bursting gameplay remained central to the Pang experience.
