Each level is presented as a scrolling two-dimensional side view. Lemmings enter from a designated entrance and walk continuously, turning around when they meet obstacles. The objective is to save the required number before the available time expires.

Players assign skills such as Climber, Floater, Bomber, Blocker, Builder, Basher, Miner, and Digger. Skills are limited by level, and progression depends on solving increasingly intricate layouts with the required survival percentage. The game is organized into themed level groups with multiple difficulty tiers.

Study the entire route before spending a skill. Identify where the first blocker, builder, or digger must be used, then preserve rare abilities for places where no alternative exists.

Use pauses and controlled release rates to separate lemmings when timing matters. Test dangerous sections deliberately, and remember that a solution can require sacrificing a lemming or detonating a blocker to open the final route.
