Sub Mariner Video Slot is a newer Marvel Comics slot based upon the longtime popular character Sub Mariner. As expected, this is a marine-theme complete with squids, submarines, and much more. The bonus round is semi-arcade style where you tell Sub Mariner which boats and submarines to destroy. During this process, you find out how much you win or how many free spins you will receive. There are wilds, scatters, free spins, and a ton more with this slot!
