How to Play

The start of the game looks like this:

  1. Firstly, you have to load the slot on a browser page or smartphone
  2. Then you need to read the rules of the game
  3. After that, you have to choose a bet from €0.15 to €45
  4. Finally, you can start spinning the reels

The slot has 15 fixed lines and 8 symbols that pay winnings for combinations. In addition, there are 2 special symbols in the game. The Wild gives you an increased chance of winning, while the Scatter is responsible for triggering the bonus round.

To fine-tune the slot, you can use a separate menu. By opening it, you can enable the Quick Spin option, as well as increase or decrease the volume of the game soundtrack. You can also turn off the game music and sounds here.

Deep Sea RTP and Volatility

6.9 
The RTP of the slot is 94% and the volatility is low.

Return to Player is a statistic that reflects the possible amount of bets that can be returned in one game session. The RTP value makes sense if you play for a very long time. For example, a week or a month in a row. In other cases, do not pay too much attention to it.

In turn, the volatility of the slot makes it possible to find out how often prize combinations will fall on the grid. With low volatility, this will happen too often. 

Theme

8 

The graphics in the game are perfect. Before it begins, the player plunges into the dark depths inhabited by mysterious creatures. A diver can be seen on the left side of the screen. He explores the bottom in search of treasures lost here.

It's nice to note that all slot symbols are not static. They move, shimmer and even, perhaps, make some sounds. The sounds of game events here are perfectly balanced, they are quiet, soft and pleasant.

The symbols of the game are various sea creatures. The highest paying symbol here is the live green Seaweed. The game’s Wild is in the form of the Capture and the Scatter similar to an underwater camera. It is worth noting that in the bonus game, the Angler Fish takes on the role of the Scatter, and the Wild turns into the Bubble.

More and more gamblers prefer to play on smartphones or tablets. Therefore, the world's leading providers develop their games using HTML5.

Bonus Rounds & Free Spins

7.9 

Free Spins

If you collect at least 3 Cameras anywhere in the game grid, an extra round is automatically activated in the slot. In this case, you will receive 10 free spins with the possibility of re-triggering them. You can also collect 4 and 5 Scatters, which will give you 12 and 15 free spins respectively.

Additional Wilds

In the bonus game, special symbols are replaced with new ones. The Scatter is no longer the Camera, but the Angler Fish. If three of these fish fall on the grid, 10 additional Wilds will be added to the game. In turn, the latter now has the shape of the Bubble.

The mechanics of subsequent free spins is changed. An even deeper immersion of the game screen takes place. After it, an additional 10 Wilds can fall on the grid, which occupies arbitrary positions. The deeper the gaming scene plunges into darkness, the more chances you have of getting big payouts. If you are lucky and manage to collect 3 more scatters during this round, the slot will give you 1 more free spin and the last 10 Wilds.

Deep Sea Demo Play

At first glance, the rules of the bonus games of the slot seem complicated. To understand them in more detail, try playing the demo version of the title. It can be found on this page. It is absolutely free for all our visitors.

Max Win

9.5 
The maximum win in the slot is a 35,000x bet.
Big payouts in the game are possible during the free spins. Considering the completely unexpected, but very attractive feature of adding Wilds, we can conclude that the slot may pay very generously. At the same time, do not forget about the volatility of the title, which is set by the provider at an extremely fuzzy level. Play with medium bets and try to get the bonus before you hit your spending limit.
