Safe Cracker is a game that can be used to learn and assess learning in a fun way. The idea is simple: listen to the questions and clues and enter information by turning the safe dial.
Using a stethoscope, listen to questions from a speaker inside the safe. A small screen on the door gives graphical feedback showing possible answers. You turn the dial and then press it in to select the answer. After answering 3 questions, the door unlocks to reveal a prize.
