Pac-Man is a game revolving around Pac-Man going through a maze eating Pac-Dots and fruits while avoiding the ghosts (Blinky, Pinky, Inky, and Clyde.)
Pac-Man has to eat all of the dots to progress to the next level which are represented by fruits in the bottom. The ghosts chase Pac-Man and can be stopped with the Power Pellet. When eaten, the Power Pellet turns all the ghosts blue, and Pac-Man can eat them. There are short cutscenes with Pac-Man and Blinky in-between levels.
Blinky targets the player across the maze with his fast speed and when the level is about to end, he will speed up. Pinky helps out the others by going in front of the player, trapping them. Inky will target the player, between and the other ghosts and favors the left side of the maze. Clyde favors the bottom left corner of the maze if Pac-Man is close.
Overall, I can't think of a more iconic game this one. It is a regarded one of the most popular games ever and it has definitely earned that title. I owned this game on various platforms, such as PC, Xbox 360, physical form (Pac-Man Connect and Play), and Android.
