Pengo is an arcade game developed by Coreland and published by Sega in 1982. The player controls Pengo, a red penguin that resides in the Antarctic. The game takes place in an overhead maze made of ice blocks, where Pengo fights the trolling, 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 player uses a joystick and a single button as controls. Pressing the button while pushing the joystick will cause Pengo to push forward the ice block he is facing, which will slide until it hits a wall or another ice block, crushing any intervening Sno-Bees. Crushing more than one Sno-Bee at once will increase the number of points awarded. There are a total of sixteen levels, which repeat in order starting on the seventeenth round.
