The video game presented a little yellow ‘breaking mouth’ hero with four ghosts, Inky, Pinky, Blinky, as well as Clyde, that might eliminate the hero. Initially, the original movements of these ghosts could be easily anticipated and also memorized, making the video game all the more less complicated. Because of this, later versions were introduced that connected arbitrary movements to the ghosts, each radiating distinct individualities that were tough to forecast.
