Lemmings sold 55,000 copies on its first day in February 1991 and went on to an estimated 20 million, yet it began as an 8×8 pixel Deluxe Paint doodle Mike Dailly made for a different DMA Design game called Walker. This episode explains how Russell Kay saw a game in that endless walking animation, named it after the rodent myth, and how the studio in Dundee built a puzzle around blind forward momentum, a ticking clock and just eight skills.

The hosts break down the design of scarcity, from builders who stop after 12 bricks to the nuke button that keeps failure inside the fiction, and the office rivalry in which David Jones designed devious traps that colleagues glitched through, with Psygnosis faxing back scribbled completion times. They cover the four difficulty tiers that onboard players, Tim Wright’s public domain tracker soundtrack replacing unlicensed samples, ports to over 20 platforms, the two-mouse split-screen mode, Sony’s later 3D and EyeToy versions, and the game’s hidden legacy as the grandfather of real-time strategy, with Blizzard’s Bob Fitch citing it as the inspiration for Warcraft, plus proofs that its levels are NP-hard and PSPACE-complete.
