Joining the maze game craze rampant in the early 80s, Sega's take on the genre was novel enough to stand out from the crowd, and created one of the company's first arcade hits. Pengo features a lovable red penguin who is constantly harassed by blob-like enemies called Sno-Bees, who runs around a maze made of slidable ice blocks that also spawn his antagonists. As the Sno-Bees zero in and break down the maze blocks, Pengo can fight back by crushing them with sliding blocks or vibrating the ice walls to stun and then crush them himself. Pengo's constantly-shifting maze and ability to turn any part of the maze into a weapon give it a level of strategy that goes beyond the maze clones of its era, as your enemies are constantly both hunting you and making it harder for you to kill them.
