Scaffold Robbery

A clever physical game that saw the contestant climb across the room by placing several pieces of scaffolding into the brackets mounted on the wall. They were only provided with three, so they would have to reuse them as they went. Although not an automatic lock-in, if the contestant stepped on the floor, the crystal would decend into its chamber and become unattainable until they had cleared the floor. Of course, once they had picked up the crystal they were free to drop down and run out.
