Namor the Sub-Mariner is one of the earliest superheroes, first appearing in 1939. Hailing from Atlantis, the Sub-Mariner possesses superhuman physical qualities, the power of flight, and telepathic powers. In his time, he has been both a hero and something of a villain, sometimes saving the world, sometimes threatening to invade the surface world to teach humanity a lesson.

In the Sub-Mariner slots, you can help Sub-Mariner to defend the underwater kingdom of Atlantis from aggressive surface dwellers. By lining surface dweller symbols, who will destroy their ships. By lining up underwater symbols, you will instead increase the power of Atlantis. Namor is brutal in his defense of Atlantis, so he will reward you well for helping him conquer his foes.

Play the Sub-Mariner slots and help Prince Namor to protect the sovereignty of Atlantis.

The Prince Namor the Sub-Mariner symbol is wild, and it substitutes for any symbol other than the scatter. When it appears on reels 1 and 5, the Sub-Mariner swim feature is triggered.
