Subtopia Slot Review

Ever thought about jumping on a submarine and sinking to the bottom of the ocean searching for treasure? No, you don’t have to join the navy at all. Enough to run the free Subtopia slot powered by NetEnt. The game appeared in February 2012, and the fact that you can play in demo mode is not the only advantage.

Regular spins are complemented by Wilds, Multipliers, and Free Spins to help you win more. All the action takes place on 5 reels and 20 active lines. Given that the payout level reaches 96%, you are unlikely to leave the casino empty-handed. 

How to play this slot

Staying true to its tradition, NetEnt did an impressive job on the visual presentation. The interface is made in cartoon style with 3D graphics and different animations. All elements are conveniently located on the screen so as not to distract you from your winnings.

Subtopia slot machines settings are flexible, and you can adjust them at your discretion. Start with the active betways because they determine the possible number of combinations. In each round, you can use up to 20 lines. Then go on to the bet, which is determined by two parameters: Coin Value (1p to 50p) and Bet Level (1-10). Together, they determine the stake you place in each round: from 20p to $100. To start the game with the highest parameters, click on Max Bet.

Paytable opens the section with Subtopia slots symbols and payouts. The big round button makes single spins, though some of you will prefer the automatic mode with a preset number of auto spins. That’s all you need to know for a comfortable and profitable gaming session on this submarine. 

Symbols and soundtrack 

It’s hard to imagine such an adventure without a fun soundtrack. The developers made sure that the visual and audio effects work in tandem to create a fun atmosphere. 

The Subtopia casino game comes with built-in bonuses, many of which relate to the symbols. So, you will find a Wild, which replaces the regular characters and completes the prize chain when necessary. The Compass is a Scatter that does not depend on reels and paylines. It gives instant payouts and opens the Free Spins bonus when at least three of them land. 

  • Scientist.
  • Sailor.
  • Teacher.
  • Diver.
  • Girl mechanic. 
  • Card suits (from 10 to Ace).

These are regular symbols that make combinations in the base and bonus games. Five images of the Scientist pay 2000 coins. Sailor and Teacher add 1200 and 900 coins to your account. The Diver and the Mechanic Girl are valued at 600 and 400 coins. Card suits (10, J, Q, K, A) will pay you 50 to 150 coins. These are fixed odds as there is no progressive payout system. 

Bonus options

The appearance of three Compasses on reels activates the bonus option with free spins. During this round, an additional multiplier appears on the 5th reel. Its size starts at 2x and goes up to 6x, multiplying winnings by the appropriate amount. Its value increases when the meter symbol lands on the fifth reel. 

When you activate this bonus in the Subtopia slot machine, you do not have a certain amount of free spins. They continue until the skull and crossbones show up on the multiplier meter. 

The only downside is that the FS bonus doesn’t trigger too often, so you will need to wait for it to activate. On the other hand, it’s a great chance to win more. This could end up being 30+ free spins with a 2x multiplier or even more. Moreover, you could hit the jackpot of 120,000 coins!

Unfortunately, this is the only bonus feature. We haven’t found any mini-games, jackpot wheels, or gamble features. It could certainly upset you a bit, but it doesn’t spoil the overall experience. 

Pros and cons of the Subtopia slot

Video slots from NetEnt are known for their excellent graphics and dynamic gameplay that guarantee a great gambling experience. Detailed symbols, a fun soundtrack, and several bonus options will make your stay on the submarine comfortable and profitable. The Subtopia game should be on your Must-Try list for several reasons.


  • Unlimited free spins.
  • Extra multipliers.
  • High RTP (96%).
  • Adorable graphics. 


  • Only one bonus round.
  • May take a while before the next free spins are triggered. 

If you lack adventure and money, this slot machine seems like the best solution. Despite the lack of a variety of bonuses, the options offered are still lucrative. 

Where to play

You do not need to go anywhere to play for free. Just run the Subtopia demo slot on our website and bet as much as you want. However, if you’re looking to win real money, we have found some great casinos to choose from, such as Slotum, Mr Green, Bet365, VideoSlots, and Million Vegas.
