Pressure Pads

The objective here was to place a weight of one or more (the unit is unspecified) on each of four pressure pads. The four weights were as follows: two, one, one half and a further one half. The contestant also had a small bridge, which allowed the two weight to be placed on two pads. With each pad bearing a weight of at least one, the crystal would rise further up a tube. When all four were correct, the contestant would be able to reach the crystal. The contestant in the xmas episode of that year was able to win by dragging one pad over to the crystal and standing on it.
