Nitropolis 3 Game Background

ELK Studios is a fairly new game developer based in Sweden doing some exciting things with standard slot game mechanics. Founded in 2012, ELK Studios has released a plethora of game titles with the Pirots slot and the Cygnus 2 slot some of their most popular titles.

Nitropolis 3 Game Design

The 6-reel, 4-row base gameplay table is designed inside an industrial-style frame that can expand as additional rows get unlocked. The frame takes up much of the play screen with flammable gas canisters, toxic waste barrels and pipes of bright green fluid, adding to the chemical factory feel of play. The backdrop in Nitropolis 3 is a tropical beach complete with a deckchair and cocktail to the left of the screen beneath blurred palm trees.

Nitropolis 3 Mobile

Thanks to the HTML5 software that ELK Studios has included, gamers can spin the reels of Nitropolis 3 with a range of devices and a secure internet connection. This is a popular feature included in many online slot games with more people than ever choosing to play with mobile devices like tablets and smartphones.

Nitropolis 3 Slot Symbols

There is a brilliant selection of symbols in the Nitropolis 3 slot. The payline count in play here begins at 4096, though adding more rows to play will increase this to a count similar to some UK megaways slots. In addition to this, there is also a "Both Ways" bonus modifier in play that sees payline work from both left and right directions!

Nitropolis 3 Bonus Features

Various added features in Nitropolis 3 match the interesting theme, from Nitro Reels to a classic Free Spins round. The popular cascading reel feature can remove symbols involved in combinations from the grid and fill the space with new ones from above. As mentioned, each cascading reel trigger could add another row of 6 symbols to the play grid. This can result in a maximum 6x8 grid in play!

The classic Wild symbols that substitute for other base game symbols appear in this Nitropolis 3 slot. The Redrop symbol could hold the bonus and Nitro symbols in play and spin the rest of the grid if it lands. The Nitro match symbol matches Nitro symbols with a base game symbol on an adjacent reel in play; the Nitro Upgrade symbols could change adjacent symbols to higher-value ones. In addition to this, the Nitro wild symbol could replace adjacent Wild Nitro symbols with wilds if it lands!

There are small and large Nitro Reels in play that could cover 2 or 6 symbol places if they land on a reel. These large nitro reels cover 2 reels in play when they land with a maximum of 6 2x2 base game symbols in play. There are also base game symbols that can land 2x2, 3x3 or 4x4 in size at random in Nitropolis 3, and this is before the main bonus feature in play!

Nitropolis 3 Free Spins

Landing between 3 and 6 Bonus symbols in a single spin could trigger 8, 12, 16 or 20 free spins in the Nitropolis 3 slot. In this feature, all Nitro symbols that may land could become sticky for the remaining spins and any additional rows unlocked are not reset after a cascade ends, remaining in play for the rest of the spins.

On top of this, landing a combination of 2, 3, 4 or 5 bonus symbols with a Super Bonus symbol could trigger triggers a Super Bonus round played with 8 rows and the Both Ways mechanic in play!

Nitropolis 3 Slot Summary

The wide range of bonus features in play should make Nitropolis 3 a popular addition to any casino game library. The theme shows why this series of games has remained so popular for so long.
