The player in Pac-Man controls a character of the same name through a maze filled with little dots. But, the player isn't the only one traversing the maze. There are four enemy ghosts bent on catching Pac-Man, resulting in the loss of one life. The player's goal is to clear the little dots by eating them, completing the level and sending the player to the next level, all while avoiding those pesky ghosts.

But, Pac-Man has a trick up his sleeves for the ghosts. There are four larger, flashing dots called "energizers" of "power pellets." When Pac-Man eats an energizer or power pellet, he turns the tables on enemy ghouls allowing him, for a limited amount of time, to eat the ghosts. The player knows when the enemies become vulnerable because they change color to blue and wander in a more daze-like fashion. Points are given for each enemy captured when in this state, and the points for each consecutive ghost increase when the player gets them with one power pellet power-up. When the energy from a power pellet begins to wear off, the ghosts start flashing from blue to white quickly, letting the player know that he/she will soon become vulnerable again to the crafty menaces.

Each ghost, designated by a different color, has a unique personality and set of abilities. Blinky (red) directly chases after Pac-Man, while Pinky (pink) and Inky (cyan) always attempt to get in Pac-man's way, positioning themselves where they believe the player is headed. Clyde (orange) waffles between chasing Pac-Man and running away from him.

Points are earned for each dot and power pellet consumed, and for each ghost eaten while energized. Points are also awarded for eating the bonus items, often fruit, which randomly appear under the center box and stay for a short period of time.

Two big lips smacking in the middle of your face, Chomping on those dots to stay ahead in this race. Stay ahead of those goblins, 'cause they're trouble no doubt. Get yourself nabbed just three times and you're out. But there's good news for you when you rack-up the score! REACH 10,000 POINTS AND YOU GET ONE TURN MORE!

Bite an energy dot and the goblins turn blue, and that means 50 more points for you. It's also your chance to turn the table. So chase those goblins and bite while you're able. The more goblins you grab, the more points you score. 200, 400, 800, then more!

But when they start blinking, you better 'turn track, 'Cause that's when the goblins' true colors come back. The goblins are coming, they're on the attack, man. You like to chomp dots, but they like chomping PAC-MAN.

Blinky is fastest, so watch where he goes Pinky is sneakier than anyone knows. Inky has quite a few tricks up his cape. Clyde cuts you off so there's just no escape.
