Nitropolis 2 Online Slot Review

The dogs are back in town for with the Nitropolis 2 online slot from ELK Studios. It’s the follow-up to a massively successful game where canine characters and a karate-kicking cat rule a dystopian future. It’s a 6-reel, 4-row game with 4096 ways to win, but special Nitro Reels can deliver a colossal 191,102,972 winning ways.

In-game modifiers include stacked and sticky wilds, reels with only high value symbols on them, respins, and matched reels. Trigger these features during a free spins bonus round and they remain active for the rest of the bonus games.

Nitropolis 2 is a medium volatility game with average returns of 95%. Play on a PC or mobile at our top ELK Studios sites and you can win up to 10,000x your wager, or 1,000,000.00 at the maximum stake.

How to Play the Nitropolis 2 Slots Game

Like the original, the Nitropolis 2 slot machine is set in the future, with a Blade Runner-style city behind the reels. Symbols include graffiti effect playing card icons, 4 gang logos, such as ‘Pug Thugs’, and ‘Gritty Kitty’, and the 4 cartoonish gang leaders. These guys add a touch of humour to the game, particularly the wide-eyed pug with a shotgun.

It’s a complex game, but still easy to set up on your PC, iOS, Android, or Windows mobile at our recommended Pennsylvania slots sites and the top New Jersey slots sites. Click the pile of coins on the control panel to reveal wager options from 0.20 to 100.00 per spin and you’re ready to go.

It comes with an automatic spins option, launched with a click on the circular arrow, and the 3 small lines open up a paytable. This shows you how much you win when 3 or more matched symbols land across the reels, starting from the left. Top dog is the wolf in a baseball cap, which pays between 1x and 3x your wager, depending on how many reels he’s seen on.

Free Spins & Other Nitropolis 2 Slot Features

If you like feature-filled games, look no further, as the Nitropolis 2 slot machine has a huge range of bonuses. On every win, all non-winning symbols lock in place as the others respin once more. If this creates a new win, you get a further respin, and so on, with no maximum limit to how many times this can occur.

Nitro Reels appear at random and these hold between 4 and 12 examples of the same symbol, increasing the number of ways to win for the spin. Nitro Boosters above each reel add random modifiers to the game. These include further respins, a win both ways mechanism, stacked wild symbols, reels with symbols matched to those on their left, or reels with only high paying symbols on them.

If the Mad Max-like truck appears in between 3 and 6 places at once, you claim between 10 and 25 free spins. Any Nitro Reels that land during this feature will remain in play for the remaining free spins, making it easier to build up a vast number of winning ways.

Maximum Wins, RTP, & Volatility of the Nitropolis 2 Slot

Wins are capped at 10,000x your wager and if you have the maximum stake of 100.00 on the spin it adds up to a payout of 1,000,000.00. Nitropolis 2 is a game with a medium volatility and average returns come in at 95%.

Our Verdict on the Nitropolis 2 Slot Machine

This is a relatively complex game, with numerous features, so perhaps not one for novices. However, if you have some experience, the Nitropolis 2 slot is a fantastic game, with great visuals and thrilling features.

Respins on every win can easily lead to several prizes in a row, and the Nitro Boosters can add a modifier to the game at any time. It’s in the free spins round, with sticky Nitro Reels, that you are most likely to build the highest number of ways to win. It becomes easier to create winning combinations with more ways, and if you get anywhere near 191,000,000, huge payouts are sure to come your way.

Visit a world run by gangs of pets and play the Nitropolis 2 slot machine at our best Pennsylvania and the best New Jersey slots sites.
