One could very well draw certain similarities with the famous fictional journeys of the extraordinary Captain Nemo and his one-of-a-kind Nautilus submarine. Still, it’s not like it is a complete copy either, far from it, as here there are enough original characters that one can easily create a new story!

If you find yourself initially intrigued about what we’ve had to say about this online video slot so far, then be our guest and read through the entire slot review below!

Subtopia Slot: Betting Options

This online slot machine from NetEnt is a 5-reel as well as 20 payline slot game, and, as we mentioned above, it appears to be set in some submarine. The reels here spin on what looks like a typical submarine window, and this window provides the player the opportunity to look out and see an amazing underwater city!

There is even a soundtrack of industrial noises and sonar bleeps, which perfectly complement these graphics.

Moving on to the symbols this slot offers, you’ve got standard playing card symbols, which stand for the low-value symbols (even though NetEnt has made sure to give even these symbols a special themed flavor). And since we are aware that it’s the high-value symbols everyone is waiting to know about, let’s just say that there is a whole range of well-designed and beautifully-drawn characters representing them.

Thus, we’d be looking at an odd, purple-haired engineer, as well as a diver with a magnificent mustache, a lovely and smart-looking blond scientist, then the captain himself, along with yet another scientist, this one with red hair. 

And since we would never forget to mention the special symbols in a slot game, we won’t in this case either! So, you’ve got your Scatter Symbol, which happens to be represented by a compass, and also your Wild Symbol, which has taken the form of a golden icon. But hang on, as there is even a random multiplier symbol, which makes its appearance in your main game. We’ll talk more about these later on.

The bets per pay-line range from £0.01 to £5.00, while the bets per spin in this game range from £0.01 to £100.00, which, as we’re sure you’ll admit, makes it ideal for any player out there, no matter the size of their budgets. Then there’s the Jackpot, which amounts to a pretty decent 2,000x that of the player’s bet!

Bonus Features & Free Spins

You should know that the main bonus game is triggered by you landing 3, 4, or 5 of those compass Scatter Symbols which we already mentioned, absolutely anywhere on your reels. One more thing worth knowing about the bonus feature is that the number of spins that the player can receive in this special round is, theoretically speaking, unlimited!

However, it will still end once the Multiplier Meter stops on this particular ‘skull and crossbones symbol’ – we can’t think of a better one to symbolize ‘game over’, can you?  This specific meter is located to the bottom-right of your reels.

This meter also randomly changes between a multiplier of either 2x, 4x, or 6x, before, eventually landing on the dreaded skull and crossbones symbol.  At times, this can indeed be quite a profitable bonus game and at other times…not so much. At least, that’s our personal experience with it.

Subtopia Slot: Conclusion

What else is there to say but to point out that this is once again a slot success coming from the great NetEntertainment, and if you feel inclined to agree with us, then you can easily give it a try for yourself on one of our top-rated online casinos. Best of luck to you!
