Your task is to rescue the Lemmings across 120 levels of fast-paced puzzling. These creatures simply walk blindly through the world in the hope of reaching safety at the end of the level – unfortunately, these levels include steep drops, gaps in the ground, barriers, and rivers amongst other hazards.

You are in control not of any individual Lemming, but of a cross-hair, which can be moved over any of the Lemmings. Along the bottom is a selection of functions that can be assigned to a Lemming, including climbing, floating, and bashing. You must click to select the appropriate function, then click on the Lemming to activate it. Each level has a different range of skills on offer, a different amount of Lemmings, and a different percentage target in order to progress.
