Pengo is the arcade game Sega released in 1982: a penguin moves through a stage of ice blocks, pushing them to crush the Sno-Bees chasing it, or lining up three diamond blocks for bonus points. Its push-and-crush mechanic, combined with a clear and direct maze design, made it one of Sega's biggest hits of the golden arcade era, on par with Pac-Man or Frogger in popularity.
It's also remembered for its music: the background melody is an electronic version of "Popcorn," the instrumental piece by Gershon Kingsley that was already a radio hit before reaching the arcade. Pengo was ported to a huge number of home computers in the 80s, cementing its place among the essential classics of the period.
