Namor the Sub-Mariner is a fictional character comic book superhero appearing in books published by Marvel Comics. The mutant son of a human sea captain and a princess of the mythical undersea kingdom of Atlantis, Namor possesses the super-strength and aquatic abilities of the Homo mermanus race, as well as the mutant ability of flight, along with other superhuman powers. Through the years, he has been alternately portrayed as a good-natured but short-fused superhero, or a hostile invader seeking vengeance for perceived wrongs that misguided surface-dwellers committed against his kingdom. The first known comic book antihero, the Sub-Mariner has remained a historically important and relatively popular Marvel character. He has served directly with the Avengers, the Fantastic Four, the Invaders, the Defenders, and the X-Men as well as serving as a foil to all of them on occasion. Now when you know a little about this Marvel character, let’s play a slot devoted to him, shall we?

“The Sub-Mariner” is a 5-reel, 25-payline slot from Cryprologic. The  background of the slot is full of slowly undulating waves with lots of ships in the distance, and you will also notice the Sub-Mariner himself gliding through the water as you play the game. On the reels you will find such symbols as the Sub-Mariner, captains, monsters, submarines, bombs, anchors, necklaces, harpoons and many more. Although the graphics and animations are rather simple, they perfectly reflect the atmosphere of the original Marvel comic books.

The game is packed with special features, such as Wilds, Scatters, Free Spins and Bonus Games, giving you more chances of winning great prizes. 

The Sub-Mariner is the Wild symbol. His job is to complete any winning combination that he finds himself part of, and he additionally doubles the winnings as well. However, the only symbol that cannot be replaced by the Wild symbol is the Scatter. 

What is more, if 3 or more Sub-Mariners appear anywhere on reels 1 and 5, you will trigger the Sub-Mariner Swim feature. Sub-Mariner will then swim across the reels, changing some symbols into Wilds. 

The game logo works as the Scatter and awards decent prizes when at least 2 such symbols appear anywhere on the reels. 

There is also the Sub-Mariner Protector feature, which is activated by 3 or more Scattered Logos appearing left to right. You will be asked to select 3 of the 6 warships and submarines to win credits or Free Spins with all prizes doubled. 

As all Marvel slots, “The Sub-Mariner” is linked to three progressive jackpots: Hero Jackpot, Super Hero Jackpot and the biggest Marvel Hero Jackpot. These Marvel Jackpots are awarded randomly, so you don’t need any matching symbols to win them. However remember that the size of the wager determines the chance of winning a jackpot. In other words, the bigger your bet, the more chances you have to win one of the jackpots.

Cryptologic doesn’t base their slots only on well-known Marvel characters appearing in block-buster films, but they also choose characters that are less popular, but at the same time aren’t less interesting than Captain America or Wolverine. “The Sub-Mariner” is a good example that an entertaining game doesn’t have to star only the best-known super heroes.
