Lemmings

Lemmings is a puzzle game in which the player guides groups of small, green-haired creatures through hazardous side-scrolling levels by assigning them specific skills.

Each level begins with a group of lemmings dropping from an entrance hatch into the environment. The lemmings march forward automatically, turning around only when they hit a solid wall, and will walk into pits, water, lava, traps, or other hazards unless the player intervenes. The goal is to guide at least a required percentage of the lemmings to the exit before time runs out. Some levels require saving only a small number of lemmings, while others demand careful planning to rescue large groups under strict limits.

Instead of controlling the lemmings directly, the player uses a cursor to assign skills from a toolbar at the bottom of the screen. The available skills and their quantities vary by level. Climbers can scale vertical walls, Floaters survive long falls, Bombers explode after a short countdown, Blockers stop and redirect the flow of other lemmings, Builders create staircases, Bashers tunnel horizontally, Miners dig diagonally downward, and Diggers dig straight down. Choosing the correct skill for the correct lemming at the correct moment is central to solving each puzzle.

Gameplay involves balancing speed, timing, and precision. Lemmings enter the level continuously, and their flow must be managed so that they do not rush into danger, become trapped, or crowd too tightly in confined spaces. The player can also adjust the release rate, controlling how quickly lemmings emerge from the entrance hatch. Raising or lowering this rate can be important for preventing crowding, delaying the group while a route is prepared, or finishing a level before time expires. The player may need to build bridges over gaps, dig through terrain, redirect groups, isolate individual lemmings, or prepare a safe route before the main crowd reaches a hazard.

Some levels provide generous skill supplies and straightforward solutions, while others allow only a few carefully chosen actions and require experimentation. Many puzzles are built around trial, error, and refinement, with players gradually learning the correct sequence and timing of skills needed to guide the group safely. The game’s presentation contrasts cute, simple character animation with darkly comic hazards and slapstick failure, giving the puzzles a distinctive personality.

The game includes 120 levels divided into four difficulty categories: Fun, Tricky, Taxing, and Mayhem. These categories form a gradual difficulty curve, with early stages introducing basic skills and later levels requiring complex, multi-step solutions. Level elements include destructible terrain, indestructible barriers, one-way walls, deadly traps, water, lava, and narrow passages. If a level becomes unsolvable, the player can activate the nuke option, causing the remaining lemmings to self-destruct so the level can be restarted. The game tracks performance by showing how many lemmings were saved, the required rescue percentage, and the time remaining. Many versions provide passwords after completed levels, allowing players to return to later puzzles without replaying the game from the beginning.

Lemmings was released on many computer and console platforms, with ports adapting the interface, graphics, sound, level access, and control methods to different hardware. Some versions also include a two-player mode, in which players compete to guide lemmings to their own exits on shared or split-screen stages. Despite these differences, the central puzzle structure of assigning limited skills to guide a crowd of lemmings to safety remained consistent across most versions.
