A unique, and rare, feature in this video slot are the two wild symbols. The submarine symbol will appear on reels 1 and 2, 4 and 5, leaving the 20,000 Leagues logo symbol to appear on the middle reel. The submarine can substitute for all symbols except the 20,000 Leagues logo; the logo substitutes for anything. When a sub and a logo appear together, they’ll trigger 10 free spins, with doubled winnings.
This game plays 80’s music in the background, to calm and relax you while you dream of what to do with the winnings. Maybe share them with the mermaid…. Together with the animation, the bleeping and other authentic sounds from the submarine, 20,000 Leagues draws you inside a great sea adventure.
Another interesting feature in this slot is that if the Captain Portrait symbol appears five times on active payline he will invite you to sit at the Captain’s Table and pay out 600 times the line bet. If he is covered three times on an active payline, he will pay 30 times the line bet and 150 times if he shows up on 4 of them.
