Lemmings is a puzzle-platformer video game originally developed by DMA Design in Dundee, Scotland and published by Psygnosis for the Amiga in 1991 and later ported for numerous other platforms. The game was programmed by Russell Kay, Mike Dailly and David Jones, and was inspired by a simple animation that Dailly created while experimenting with Deluxe Paint.
The objective of the game is to guide a group of anthropomorphised lemmings through a number of obstacles to a designated exit. To save the required number of lemmings to win, one must determine how to assign a limited number of eight different skills to specific lemmings that allow the selected lemming to alter the landscape, to affect the behaviour of other lemmings, or to clear obstacles to create a safe passage for the rest of the lemmings.
Lemmings was one of the best-received video games of the early 1990s. It was the second-highest-rated game in the history of Amstrad Action, and was considered the eighth-greatest game of all time by Next Generation in 1996. Lemmings is also one of the most widely ported and best-selling video games, and is estimated to have sold around 20 million copies between its various ports. The popularity of the game also led to the creation of several sequels, remakes and spin-offs, and has also inspired similar games.
Lemmings is divided into a number of levels, grouped into four difficulty categories. Each level begins with one or more trap doors opening from above, releasing a steady line of lemmings who all follow each other. Levels include a variety of obstacles that prevent lemmings from reaching the exit, such as large drops, booby traps and pools of lava.
