Safe Cracker

Safecracker is a 1997 puzzle adventure game developed by Daydream Software and published by GT Interactive. It casts the player as a security professional, whose goal is to infiltrate the mansion headquarters of a safe manufacturer and break into 35 of its unusual models. Each safe is guarded by a different type of puzzle, including sliding tiles, anagram codes and translations from braille. The player's progression is nonlinear: the mansion can be explored, and its safes unlocked, in multiple orders. However, the game must be completed within a 12-hour time limit.
