Under the Sea Slot Betsoft

Find fortune in the depths of the ocean in Under the Sea, a 3D video slot developed by Betsoft. Swim with all sorts of fish and maybe even find a fabled mermaid in this aquatic game. Play Under the Sea for free on this page, or go to any of the Betsoft casinos in our listings to play for real money.

Before you dive into the water, take the time to choose your bet. Click the “Choose Coin” button on the bottom-left to set your base denomination. Then, add coins to each payline using the “Bet Per Line” panel. If you do not want to play all 30 paylines, use the “Select Lines” button. Hit “Spin” to start playing, or use “Max Bet Spin” to play with the highest possible bet of 150 coins. “Au­top­lay­” on the top-left can be used to spin automatically.

The Under the Sea base game is easy. Just get matching Fish or Mermaids from the leftmost reel to the right to win amounts shown in the paytable. Wild Pearls make it easy to get winning combinations, and they come with consecutive 2x multipliers: 1 symbol in a combination pays 2x, 2 symbols pay 4x, and 3 symbols pay 8x.

Under the Sea offers two different bonus rounds. Get 3 or more scattered Ships to initiate Free Spins with 2x multipliers on all wins. The Treasure Hunt Bonus Round will be triggered if you get 3 or more Bonus Chests on a payline.

I can’t say that I am a big fan of Betsoft slots, but I am playing them from time to time and I decided to try a new slot because I was already bored of the Microgaming and NetEnt slots so I chose this one! It is a 5 reel slot, with 30 paylines and a minimum bet of 0.60 euro. Because my Skrill account was showing 35 euro, I decided to deposit this amount to a casino and to try my luck at this slot. As we know, the graphics of the Betsoft games are really good and impressive so this slot isn't an exception, I like the symbols, also the theme about underwater creatures. I started to spin and I noticed that the game is not running so smooth, the 3D animations are making this game very hard to handle for my PC.

Regarding the features I could say that I am happy with the Free Spins and Bonus features, also it has a Wild symbol that pays good in the main game. I won from the free spins 33 euro when I managed to catch for the first time, I think that it was a decent win thinking at the 0.60 euro stake. I don’t like the speed of this slot, it takes some time for the reels to stop, the good graphics and the 3D animations are slowing down the gameplay.

I recommend you to play this slot if you have a good PC, you like to wait until the reels stop and also if you want to have some fun because the payout rate isn't as good as the other slots have, NetEnt or Microgaming slots for example!

Only a 7 for the graphics although I like the theme and the symbols, the animations aren't good in my opinion because are slowing down the entire game!

Another 7 will receive the payout rate because in the main game you won’t be a able to win lots of money, only in free spins and bonus round!


The only bad thing is that the game doesn't run smoothly, I don’t like to play it for a long time because I will get bored!

Deep under the sea an ancient shipwreck full of treasures favors the proliferation of coral reefs that are home of a variety of colorful and likeable fish under a smiling and beautiful mermaid care who is also responsible for giving life to one of the most known games of Betsoft gaming and an oyster with a perfect pearl inside is responsible for bring smiles to players.

This 3D slot was one of my favorite ones to play in Betsoft casinos for a long time and have more good memories than bad ones, nowadays I don´t use to play it maybe because there are new slots developed by this company plenty of interesting features that catch my eye a lot but it does not mean Under the Sea has lower qualities or is less exciting. More simple style makes faster this game and maybe more relaxing, I think ocean ambiance and smiling characters faces, help with this. In my personal experience this game was enough profitable some times and when winnings trends went against me I just changed so I never had important losses because of it.

Under the Sea has 5 x 3 reels and 30 pay lines, standard symbols are a little mermaid and 5 different kinds of fish, wild symbol is a beautiful pearl inside an oyster with 2x, 4x and 8x multipliers depending if it is 3, 4 or 5 wilds on a same line, shipwreck scatter symbols trigger 8 to 15 free spins and 3 or more chest bonus symbols take you to a bonus land where you may open nine chests one-by-one and take their treasures until the collect word appears. In my personal opinion winning average is enough good here and my preferred feature is the bonus chests where I was really lucky the most of times. Fun and pretty is all I can say about this slot game.

„Under the Sea“ is a slot from BetSoft casinos. It is not as good as „Under the Bed“and „The Curious Machine“ but it is not as weak as „The True Sheriff“ or „Rook 's Revenge“.(It is very odd that here in BetSoft casinos I encountered the widest range of game quality from the very best possible to the very weakest).

This slot has 30 paylines and it would have been better if the game were more generous with the winnings. The graphics theme of the slot shows the underwater life, the fish figures depicted by the symbols being the most beautiful. Besides the fish there is here an attractive Siren, the Shells which are Wild, the Ship Wrecks that are scatter and the Gold Trunks that trigger the Bonus Game. Unfortunately as I said, the slot is pretty stingy with the wins. Playing with a total bet of 30 coins I was very quickly in loss (with a total loss of over 2000 coins after about 150 spins) . The wins are here found on the average about once every 4 spins (that is, less often than at the other BetSoft slots) and have a value between 5 and 100 coins depending on which fish type is aligned. Moreover, the Wild symbol that here doubles the value of the winning combination it enters, occurs very rarely (about every 5 spins) and does not help at all.

Instead of Wilds, in about 150 spins I entered 3 times the Free Spins round (8 Free Spins for3 „Scatter“s on the screen) . Once I won 60 coins, second time 350 coins, and third time about 140 coins, which did not brought my balance afloat. The only good word here is that 2 „Scatter“s pay more than the total bet - 60 coins.

Bonus Game is given here by 3 Gold Trunks symbols and I have played it twice. The Bonus Game consists of randomly choosing a Trunk to reveal a treasure value and wins are comparable to those from the Free Spins round. Unfortunately at the end of the second Bonus game the slot stopped to respond.

My final opinion is that the graphics quality of the slot is nice, but a little too stingy when it comes to wins it offers.
