Pengo (World, not encrypted, rev A) - MAME machine

Arcade Video game published 42 years ago:

Pengo © 1982 Sega.

Pengo is an action game set in an overhead maze constructed of ice blocks. The player controls Pengo, a red penguin that lives in the Antarctic and fights the blob-like Sno-Bees. The objective of the game is for Pengo to survive a series of rounds by eliminating all Sno-Bees, while amassing bonuses by bringing together the three diamonds dispersed in the maze.

The Maze itself is an interactive environment. Each section of wall is a block of ice that can be pushed onto the Sno-bees to destroy them. Pressing the button while pushing the joystick will cause Pengo to push the ice block in the direction he is facing. The block will slide until it hits either a wall or another ice block, crushing any Sno-Bees in its path. Crushing more than one Sno-Bee at once will increase the number of points awarded.

As the player crushes the Sno-Bees, new ones hatch from eggs located within ice blocks. Each time a new one hatches, blocks containing eggs that have still not hatched yet are briefly identified by flashing the color of that round's Sno-Bees. A certain number of eggs will hatch immediately at the start of each round - this is also the maximum number of active Sno-Bees at any one time in the round. Eggs can be eliminated by crushing the ice blocks that contain them. If Pengo pushes a side wall at the edge of the screen, the water vibrates, any adjacent Sno-Bees will be briefly stunned and are eliminated if Pengo walks over them in this state.

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 but can be re-used by Pengo.

After 60 seconds elapse in a round without a player or enemy death, the game enters into sudden death mode; the music tempo and movement of the Sno-Bees accelerates. If a single Sno-Bee remains in the round, a jingle plays and the Sno-Bee accelerates in an attempt to reach a corner, where it safely fades away.

There are a total of 16 rounds in the game. After round 16 is cleared, the game loops back to round 1.

Pengo is known to have two different marquees. One marquee depicts Pengo standing next to the game's logo, with one leg up on an ice block, and one hand pushing against the O in the logo; the Sega logo appears in small print directly underneath the O. The other marquee depicts Pengo pushing an ice block, with the Sega logo appearing on the lower right corner of the marquee in a larger print.

TRIVIA
Pengo was released in September 1982 in Japan, in October 1982 in North America, and in December 1982 in Europe.

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 surfboard.

The color for the Sno-Bees is different in each round and follows an eight-round pattern: green, red, yellow, pink, orange, yellow, light blue, yellow.

Demonstration gameplay in the attract mode always plays Round 5, with the orange Sno-Bees.

The song that is played during the brief intermissions that appear after every even-numbered round is cleared is "Ode to Joy" from the fourth movement of Beethoven's Ninth Symphony.

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

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

TIPS AND TRICKS

• 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-Bee eggs are still unhatched and hidden in ice blocks.
• A certain number of Sno-Bee eggs will hatch immediately at the start of each round. This is also the maximum number of active Sno-Bees you can have at any one time during the round. In rounds 1-4, this number is three; in rounds 5-16, it is four.
• Every time a Sno-Bee egg hatches, some ice blocks will flash, revealing the locations of Sno-Bee eggs that have not hatched yet. You can destroy the ice block to eliminate that Sno-Bee egg before it even hatches.
• 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.
