How to play?
The vaults of a London diamond exchange are patrolled by a robot. His simple movements along the rows of trays of diamonds are made by giving him simple commands. When an intruder is detected it is your job to guide the robot to arrest the villain.
On the first screen click the Play button to start. If it is your first time or to brush up on your skills, click the Practice button which allows you to play the game but without scoring and not against the clock. The next screen shows a plan of each level in the vault and the intruder will be seen helping himself to a tray of diamonds. You can only move on the floor area and through the gaps between the trays of diamonds.
