An instrument for filling a substance supply container of a device for personal care treatment has a filling needle having a proximal end connected or connectable to a storage reservoir and a distal end, a substance transport conduit extending from the proximal end to at least one outlet provided in a radially facing surface portion closely adjacent the distal end of the filling needle. The insertable layer, wire frame and inner crucible are preferably composed of platinum. The gaming device activates the reels and initiates the award mode when the trigger symbol is indicated on one of the paylines associated with the reels.
