We are more than pleased when we see a slot game from Net Entertainment needing a review, as we know it is going to be a good day and a good slot. This time, we are reviewing the perfect subterranean game called Subtopia Slot and it might remind us all of Captain Nemo and his Nautilus submarine, but this game has enough characters on its own to be a stand-alone story, so here goes nothing.

Subtopia Slot is a five reel 20 payline online video slot that has a super cool underground theme. TO spin the reels and expect some of the best prizes that this game can offer, you need to fill in the registration form and we will take you to our casino, where with the very first deposit you earn yourself a welcome bonus, usually in a free spins form. After claiming the welcome bonus, set the denomination which is with a range from £0.01 all the way up to £100.00, while the best thing is the maximum amount that you can win while playing Subtopia Slot, which is a multiplier of 2,000. With an RTP of 96.10%, Subtopia has some many things to keep you on its reels.

Want to find out more about Subtopia Slot and how the symbols, paylines and bonus features work? You are in the right place!


Subtopia Slot is a slot that you definitely need to try. It has an interesting underground theme with its own characters and with a really cool story. One of the best things about Subtopia slot, just like all the modern slot games, is that you can play it wherever you want. It is responsive for all of the devices that are used for slot games such as a Mobile, Tablet, Lap Top or PC. Feel the game from the comfort of your home, on the go, in the metro or basically wherever you want.


The design of Subtopia Slot is a pretty sharp one. The whole screen is beautifully designed, and you can immediately see that this is not on the surface of Earth. You can see by the metal window around the reels, and how it stops the water from getting inside the city where all the characters of this story live. On the top of the screen, you can see the logo of the game in neon lights and cool writings that will most definitely catch your attention. The sides are reserved for the paylines that this game has, and if you mouse over them, they will appear on the screen so that you can see how they are made or what to expect when spinning the reels.

On the other hand, the bottom is for the options and adjustable features that the game has, and we can see the number of lines, level of the game as well as coin value and the speed of the reels turning. This is a rare thing among slot games, but you can sometimes adjust the speed of the reel spinning with a normal of x1, but you can set x2, x3 or x5.

The coins, bet and the win of your last spin are located below the screen as well.

How To Play Subtopia Slot

Subtopia Slot is a pretty straightforward game to be played, and with the five reels and 20 paylines, you are up for a treat from this Net Entertainment game. To spin the reels, you need to fill up the registration form on your right-hand side, and we will take you to our casino where you are eligible for a welcome bonus on your very first deposit. Once that happens, grab the deposit, which is usually in a free spins form, and set the denomination of the reels from £0.01 all the way up to £100.00.

The key thing and the reason why people return to the reels of Subtopia Slot is the maximum amount that you can win the game, which is an astonishing x2,000 of your bet. This means that the higher denomination you play with, the more lucrative wins will end up in your stake and in your pocket.

To set the highest denomination, coin value and level of the game, as well as activate all of the paylines that Subtopia Slot possesses, hit the “Bet Max” button. Although this feature seems like a big juicy bite, you should always be careful when playing it, as it may lose all of your money pretty fast. Either come up with a plan or a limit to your cash, or we suggest you completely forget about this feature.

On the other hand, the “Auto Play” will give you a more relaxed approach to the game, and it will spin the reels automatically, with all you need to set it the denomination and the number of auto spins.

Subtopia Slot Bonus Features

Free Spins

This is the main bonus game and it’s triggered by landing three, four or five of the compass scatter symbols anywhere on the reels.  The number of spins you receive in this round is theoretically unlimited but will end when the Multiplier Meter stops on the skull and crossbones symbol.  The meter is located to the bottom right of the reels.

You can see from the video below that the meter randomly changes between a multiplier of 2x, 4x and 6x before eventually resting on the skull and crossbones.  Sometimes this can be a lucrative bonus game and sometimes not so much or at least that’s our experience.


With five reels, 20 paylines, an RTP that will most definitely give you chills once you see the 96.10% number, and a free spins bonus feature to facilitate your way to the highest prizes of the game, we state the obvious – Subtopia Slot is one fantastic game.

Fill in the form and be eligible for your welcome bonus once you make the first registration. We are waiting for you!
