Nitropolis 3 Online Slot Review

The dystopian dogs are unleased for a third time in the Nitropolis 3 slot machine from ELK Studios. As you can guess, this cartoonish / futuristic slot is the follow up to two hugely successful games and expands on the innovative gameplay with even more features.

This 6-reel game gives you 4,096 ways to match symbols for a win, and any symbol can appear from 1x1 to 4x4 in size. An Avalanche mechanism removes all winning symbols, making it possible to grab multiple payouts from a single stake.

The basic 4,096 ways gets an upgrade as random symbols split into a maximum of 12 rows. Special symbols can land at any time to shuffle others, add wilds, or trigger a win both ways mechanism. During a free spins feature, it becomes easier to expand the reels, and it’s here that you have the best chance to land a massive multiplier of 50,000x the stake.

Nitropolis 3 is a highly volatile game with average returns of 95% that you can play on Android, iOS, or Windows mobiles, as well as PCs at the best ELK Studios casino sites.

How to Play the Nitropolis 3 Online Slot

Like the other games in this series, the reels of the Nitropolis 3 slot machine feature 4 cartoon pets surrounded by bits of machinery. There’s a mad scientist cat, tough-guy Doberman, and wild-eyed pug among the graffiti playing card symbols and gang emblems, such as the Gritty Kitty, and Pug Thug symbols.

The backdrop has changed from an apocalyptic / industrial setting of the others in the series, to a far more tranquil beach. The lively soundtrack matches the comic images and certainly adds to the appeal of this desktop and mobile game.

The controls are nice and easy to use with a click on a little stack of coins revealing 12 staking options from 0.20 to 50.00 per spin at the top online slots sites. Because the Nitropolis 3 online slot has such unusual gameplay and features, we would recommend that you read the paytable before you play, just so you know what to expect from this thrilling slot.

Tap the 3 small lines on the controls to reach the paytable, which has all the details on features such as Nitro Reels and Big Symbols. There’s also a list of how much each symbol is worth when at least 3 of a kind land on adjacent reels from the left, with the Doberman paying the most, at up to 5x your stake.

Free Spins & Other Nitropolis 3 Slot Machine Features

A Toxic warning sign is wild, so it can act as others to bridge any gaps in a run of matching symbols. All symbols in a win explode and new ones drop from above, while an extra row appears at the top. This Avalanche feature runs until no new combinations are seen, although the reels stop increasing in height once you have 8 rows of symbols.

Small Nitro Reels hold 4, 6, 8, or 12 compacted symbols, while Big Nitro Reels hold 2, 3, 4, 5, or 6 symbols across 2 connected reels. Big symbols of 2x2, 3x3, or 4x4 size can also appear on their own at any time.

Several special symbols can also enhance the gameplay in any spin, although the wild can’t substitute for them. The Redrop removes all except bonus symbols and Nitro Reels for a single respin, while the Both Ways symbol pays any wins on the spin from both the left and right sides.

A Nitro Match symbol transforms any Nitro Reels into symbols that match those on adjacent reels, and the Nitro Upgrade symbol upgrades Nitro Reels with extra symbol positions. If the Nitro Wild appears, it transforms all Nitro Reel symbols on the same or adjacent reels, into wilds.

Land 3, 4, 5, or 6 airship scatter symbols to launch 8, 12, 16, or 20 free spins respectively. During this round it gets easier to land big wins, as Nitro Reels remain in place, and once the grid starts to expand with Avalanches, as safety mechanism keeps them expanded for any remaining games. If a Super Bonus symbol was part of the triggering combination, reels start out 8 rows high and the win both ways mechanism is in force throughout. More bonus symbols retrigger the free spins.
