The game takes place in an overhead maze made of ice blocks, where Pengo crushes blob-like Sno-Bees by sliding blocks into them.
The player uses a four-position joystick and a single button to control Pengo, a penguin character. Pressing the button while pushing the joystick against an ice block will cause it to slide in that direction until it hits another block or a wall, if the space directly ahead of it is unoccupied by a block or wall.
If that space is occupied, pressing the button will crush the block instead. The goal is to destroy every Sno-Bee on the board by one of three methods:
Sliding ice blocks to crush them
Crushing blocks that contain unhatched Sno-Bee eggs
Running over them after stunning them at a wall
At the start of each round, a certain number of eggs hatch into Sno-Bees, while other blocks flash to indicate that they contain eggs. As the player destroys active Sno-Bees, new ones hatch from the eggs to replace them. Crushing multiple Sno-Bees with one block awards extra points. The Sno-Bees can crush blocks in an attempt to reach Pengo.
Pushing against a wall causes it to vibrate and temporarily stuns any Sno-Bees in contact with it; the player may then crush them with a block or simply run over them to destroy them. Contact with a Sno-Bee costs the player one life.
Three blocks in each round are marked with diamonds and cannot be crushed. Arranging these blocks in a continuous horizontal or vertical line awards bonus points and temporarily stuns every active Sno-Bee. If the player eliminates every Sno-Bee in less than 60 seconds, bonus points are awarded based on the time taken.
