Jr. Pac-Man

Jr. Pac-Man (c) 10/1983 Bally Midway.

One of many sequels to the legendary "Pac-Man", Jr. Pac-Man features the character of Pac-Man's son. For the first time in the series' history, side-scrolling mazes were introduced, with each maze being two screens wide.

This time, the mazes have no exit tunnels through which players can make an escape. The bonus items that appear move around the maze and are now something of a mixed blessing, as not only will they destroy any Power Pills they come across, but they will also create large dots that slow the players' movements considerably.

The Pac-Man character is once again pursued by four ghosts (Blinky, Pinky, Inky and Tim) in his quest to eat all of the dots in each maze. And as before, numerous Power Pills litter the mazes that, when eaten, allow Junior to eat the pursuing ghosts. As with previous "Pac-Man" games, cut scenes are featured between levels.


Game was available either as one of 2 kits to update a "Pac-Man" upright cabinet or cocktail table cabinet. It was also available as a dedicated game using a "Mappy"-style cabinet.

Jr. Pac-Man was developed by 'General Computer Corporation' (GCC) for Bally/Midway and is essentially an enhancement to "Ms. Pac-Man" (which is, in itself, an enhanced version of the original "Pac-Man"). Much of the original "Pac-Man" code is still present and even the 'GENERAL COMPUTER CORPORATION Hello, Nakamura.' message that featured in "Ms. Pac-Man" is present.

Jr. Pac-Man runs on a modified "Pac-Man" hardware, with additional horizontal scrolling support. This was the first "Pac-Man" game in which the maze is larger than the visible area; requiring the screen to scroll.

There are a number of hidden bonus objects that were never used by the developers. To see them, set 'CHEATS' to 'Always have blue ghosts'; play a game, repeatedly eat the ghosts until you get past 1600 points. The game was coded to deal with such high bonus values and assigns a hexadecimal value to the score value after 1600. The hexadecimal scores equate to a graphic in the game. After eating somewhere in the neighborhood of 20-30 ghosts consecutively, the hidden objects will appear. There is a rattle, a baby's dummy, a cowboy hat and a skateboard.

Abner Ashman holds the official record for this game with 1, 500, 000 points on February 2, 2002. In the game where he "officially" got this record, there was a power outage that shut down his game at approximately that score... and he still had not lost a man up to that point!

A bootleg of this game runs on the "Pengo" hardware.

A Jr. Pac-Man unit appears in the 1983 movie 'Joysticks'.

On the second maze, it's possible to 'trap' the ghosts so that you can complete a lot of the maze without them chasing you. Position Junior to either the far left or far right hand side of the maze; thus causing the center of the maze to scroll off-screen. You should see the ghosts in the corridors above the ghosts' box; they will stay in those corridors as long as you are on either the left or right hand side of the maze. This works because the game has logic to reverse monsters' direction when they go off screen.
