Super Hard levels, also called thunderstorm levels, are levels officially marked to be a very difficult level by King. They are a proper subset of hexagon levels. It is usually the most difficult level in a given episode, as each episode is limited to one thunderstorm level.
This feature is only explicitly shown on mobile. The level type color is hidden and changed to dark blue, which is ringed by a gold skull and a thundercloud above it. No Dreamworld levels are thunderstorm levels since Dreamworld had been removed on mobile by the time thunderstorm levels were introduced.
In a mobile update in February 2017, thunderstorm levels are implemented. They mark levels as "super hard levels."
Like Hexagon levels, the list of thunderstorm levels is dynamic and are usually updated at a weekly basis.
