About this game

Lock simulation
Based on the trial-and-error learning technique, this simulation shows how a lock works.

The control panel allows you to operate gates, valves and lights. Explanatory messages provide food for thought in the event of unsafe or inappropriate operation.

The simulation allows you to open all the gates at the same time, which is not realistic, but it does teach you about communicating vessels.
