is a hyper-realistic mechanical simulation game developed by Sophie Houlden, designed to teach users the physics and techniques of cracking a Group 2-style safe lock. Unlike traditional "minigame" lockpicking found in many RPGs, this simulator uses actual manipulation methods, including graphing contact points and identifying "gates" within the lock's wheels.
