Pengo (c) 1982 Sega.

Pengo the Penguin is the eponymous star of Pengo the video game. The basic layout of Pengo is akin to that of Namco's legendary "Pac-Man"; featuring, as it does, a top down, single screen, maze-like arrangement. Pengo's enemies, the Sno-Bees, are also similar to Blinky, Pinky, Inky, and Clyde - the ghosts that pursued Pac-Man; not least because Sno-Bees also come in four different varieties, each represented by a different color.

One aspect that distinguishes Pengo from the Namco classic is that the Maze itself is a wholly interactive environment. Each section of wall is represented as a block of ice, which can be pushed onto the Sno-Bees to destroy them. The Sno-Bees themselves will destroy the ice blocks as they move around each level, so speed is of the essence. Some of the blocks are 'Diamond blocks' which cannot be destroyed, and can be re-used by Pengo.

The outer wall of each level can also be utilized; if the player pushes against the wall when a Sno-Bee is next to it, the Sno-Bee will be temporarily stunned, allowing Pengo to move in for the kill.


Game ID: 834-0386

Main CPU: Zilog Z80 (@ 3.02 Mhz)
Sound Chips: Namco 3-channel WSG (@ 96 Khz)

Players: 2
Control: 4-way joystick
Buttons: 1 (PUSH)


Pengo was released in September 1982 and developed by Coreland Technology.

Pengo makes a cameo appearance in "Up'n Down". If a player manages to pass the first 4 rounds in under a minute each, he will appear in the water of round 5 riding a surf-board.

Rodney Day holds the official record for this game with 1110370 points.

A bootleg of this game is known as "Penta".


Set 2 & 4 draws its maze much more quickly and has snappy original music, whereas Set 1 & 3's music is a copy of an instrumental pop song (Hot Butter - Popcorn - 1972).

Set 2, 3, 4 correct a Test Menu Bug.

The curtain speed is fastest on Set 2.

The demo mode is different in Set 2.

Set 4 introduced a number of changes to make the game flow faster than in previous sets.
- Number of frames before the level completion time is shown changed from 32 to 8.
- Number of frames after a time bonus is calculated changed from 128 to 64.
- Number of frames before the screen wipes after the player has died changed from 128 to a single frame.

Additional changes were made in Set 2:
- Delay before player can move at the start of a stage changed from 64 frames to 16 frames.
- Delay before the next level loads after an intermission changed from 64 frames to 16 frames.
- Delay before the sky rapidly changes colors in the intro changed from 64 frames to 48 frames.


Smashing an ice block : 30 points.
Smashing an ice block with a Sno-Bee inside : 500 points.
Walking over a stunned Snow-Bee : 100 points.
Killing a Snow-Bee with an ice block : 400 points.
Killing two Snow-Bees at once with one ice block : 1600 points.
Killing three Snow-Bees at once with one ice block : 3200 points.
Killing four Snow-Bees at once with one ice block : 6400 points.
Lining up the three diamond blocks with one or zero of them touching a wall : 10000 points.
Lining up the three diamond blocks with two or more touching a wall : 5000 points.
Completing screen in under 20 seconds : 5000 bonus points.
Completing screen in 20-29 seconds : 2000 bonus points.
Completing screen in 30-39 seconds : 1000 bonus points.
Completing screen in 40-49 seconds : 500 bonus points.

Completing screen in 60 seconds and over : no bonus points.


* The last remaining Sno-Bee on the screen will try to escape. If you do not kill it before it reaches one of the corners it will disappear.

* The indicator at the top of the screen tells you how many Sno-Bees are remaining on the level, including those still in ice blocks.

* At the start of each level some ice blocks will flash. This indicates that there is a Sno-Bee inside and you can destroy the ice block to kill the Sno-Bee before it emerges.

* When you kill the last Sno-Bee you have a couple of seconds to crush up to four ice blocks for an extra 30 points each.

* Concentrate your efforts on lining up the diamond blocks. The 10000 points are the biggest single score in the game, and stunning all the Sno-Bees is also a valuable side effect. You can then kill them easily by pushing ice blocks onto them rather than running over them (400 points as opposed to 100).

* Lining up the three diamond have another side effect: the remaining ice blocks with a Sno-Bee inside will be flash to the end of screen.

* Try to kill more than one Sno-Bee at a time, as two or more together are worth more points than killing them individually.

* Easter Egg: In the attract mode, push the two joys to up, press the two action buttons and one button of start game, and it will show the credits of the game. After a few seconds, the game will reset. The wait can be stopped pushing the 1P Start button.
