Subtopia slot features


Subtopia slot is set on 3 rows, 5 reels with 20 paylines and the symbols represent the submarine crew including Captain, Inventor, Diver, Scientist, Diver, Mechanic and the card symbols of A, K, Q, J and 10. Deep blue water slot also hides the wild symbol of a golden Robot as well as a scatter Compass symbol.

The Compass scatter triggers one of the most interesting features of the game – Random Multiplier. To activate this feature, a player will have to land at least 3 or preferably more scatters, and when active you will receive a random multiplier number that changes for every spin starting from x1 and going up to x5.

  • 5 Compass Scatters = 100 X Bet Amount
  • 4 Compass Scatters = 25 X Bet Amount
  • 3 Compass Scatters = 4 X Bet Amount
  • 2 Compass Scatters = 2 X Bet Amount

Subtopia Slot Free Spins

Compass Scatter symbol is also responsible for giving you the universally loved free spins. When 2, 3 or more compasses appear on the reels, the free spins round starts. The game creators claim that it’s theoretically “unlimited.”

In reality, there is a so-called Free Spins Multiplier Meter, which makes a clunky sound and starts increasing from x2 multiplier going up to x4 and then x6. Once the multiplier meter hits the red crossed bones and skull sign, the free spins round ends.

Subtopia slot graphics and sounds

Play Subtopia slot at Maria Casino


While we appreciate the thought and effort that went into designing this slot, which features a lot of realistic underwater details and inventive, unusual characters, the overall impression is still a little bit drab. There is just not enough action and excitement, despite the reasonably good quality graphics. Let’s just say that there are more interesting NetEnt slots out there, in terms of design, gameplay and winning possibilities. We quite like some realistic industrial noises that are coming out of the submarine equipment - big plus for that, indeed.

Subtopia slot - our conclusion

We would probably recommend this slot to someone who is really obsessed with underwater and submarine adventures, or just wants to pass the time playing the game that will not make you rich in seconds, but won’t empty your pockets either. Balanced, slow and pretty average, that’s our verdict.
