The player takes the role of a penguin named Pengi who finds himself in a maze made up of ice blocks that is surrounded by an electric fence. If the blocks are kicked, they will slide along until they hit another block or the fence. If however, the block is already touching something else (in the direction it would slide), it breaks and disappears. Three of the blocks are special 'diamond' ice blocks which cannot break.
The game continues with different coloured bees in a new maze. The number of bees on screen, the number of 'reserve' bees, the speed of the bees and the intelligence of the bees all increase on each successive level, making it much more difficult to successfully line up the diamond blocks.
As with most popular arcade games of the time, there were many other unofficial clones of Pengi released for various home computers. Other BBC/Electron examples include Percy Penguin (Superior Software), Pengwyn (Postern) and more abstract interpretations like Rubble Trouble (Micro Power) but Pengi is generally regarded as the best of its type. Electron User (#2.04, January 1985) gave a particularly favourable review. Though at that time, it did not give out scores, the reviewer said "Visions' Pengi is far superior to any Pac Man program... The graphics are excellent as is the sound... If you're into arcade games, you will love this one."
