The first of these symbols is the wild icon that is represented by the logo of the “20000 Leagues” game under the water. This symbol can only land on the middle third reel and when it does that, it will substitute for any of the other symbols so it can aid players in their quest of finding the treasures that are hidden in the deep ocean. The other special icon is the yellow submarine. It also acts as the wild symbol, it will land on all reels with the exception of the 3rd reel. It has an ability to substitute for all symbols excluding of the Wild logo of the game.
There is also a free game feature that is triggered when lucky players get the two special symbols together (the logo of the 20000 Leagues symbol with at least one submarine symbol) on the reels of the game at the same time. They will earn a number of free spins on the slot.
The format of this slot is about as straightforward as possible. You’ll find three rows and 25 paylines spread across five vertical reels that is a super typical video slot layout. Players can choose between 1 and 25 paylines, though you’re better off to just play with all 25 activated. In terms of coin sizes, you can pick from $0.01 at the low end to $10 on the high end with lots of options between those extremes, and it gives the game a betting range of $0.25 to $250 per turn.
One of the most important gameplay elements for this slot, and the only thing that keeps it from being as generic as humanly possible, is that there are two different wilds. The submarine symbol shows up on the first two reels and the last two reels, and it substitutes for any of the regular symbols. On the third reel, you’ll see the 20,000 Leagues symbol that is also a wild. There are two different wild symbols because of how the bonus feature is triggered.
The Captain symbol is extremely important in the 20,000 Leagues slot for a couple of reasons. Firstly, it’s the highest-paying symbol in the game. As a matter of fact, you can earn a 5,000x jackpot for five of a kind during the normal game mode or 10,000x for five during the free spins. Four gets you 1,000x in the regular game as well.
However, it’s also structured a bit differently than most symbols in virtually every slot out there because you can get paid for just one of a kind. Get one of these guys on the first reel, and you’ll get paid at least a 2x multiplier.
Players will find a total of six symbols that are card ranks on the reels, and they are pretty plain. Five of the blue A or red K give you a solid payout of 500x. You can earn 200x for five of the purple Q or cyan J as well. The win for five of the yellow 10 or green 9 is 150x. There’s definitely not a significant drop anywhere for the five of such a symbol wins on any of the symbols, but the card rank symbols are the only symbols in the game that require at least three of such a symbol for a payout.
Features and bonuses
There are three symbols in this game that would be considered at the mid-level. The first one is the diver in the diving suit, and he pays 2,000x for five symbols. You can score 1,000x for five of the shark or of the treasure chest symbol. It’s important to realize that these are particularly top-heavy wins, and it contributes to the game having a somewhat lower hit-rate than you’d normally see. However, all three of these mid-level symbols pay for two of such a symbol or more, so that helps the situation to a degree.
The way you trigger the feature in this game is a little atypical. Firstly, you have to get the 20,000 Leagues symbol to show up on the middle reel. At the same time, there has to be at least one of the submarines on the reel that are the other wild. If you do it, then you get 10 free spins for each submarine located on the reels, so you can earn as many as 40 free turns at a time. You can re-trigger this feature too that adds even more value, and you will also get a 2x multiplier on all of your wins during the free spins.
The thing to understand about 20,000 Leagues by the Wager Gaming Technology is that it’s a fairly dated game that uses the older style of graphics. It means that you can’t really judge it by a more modern graphical standard. Instead, you have to go more off of the gameplay that isn’t exactly stellar. However, a lot of symbols in this game pay for just one or two of a kind that gives it something that stands out a bit other than the mechanism used for triggering the free spins.
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.
A unique, and rare, feature in this video slot is two wild symbols. The submarine symbol will appear on the 1 and 2, 4 and 5 reels, leaving the 20,000 Leagues logo symbol to appear on the middle reel. The submarine can substitute for all symbols except for the 20,000 Leagues logo; the logo substitutes for anything. When the submarine and the logo appear together, they’ll trigger 10 free spins, with doubled winnings.
