Slot Details

Nitropolis 2 is a six by four slot machine with medium to high volatility. And you can play the game in two modes – the normal mode and the bonus mode. The bonus mode is filled with exciting features such as free spins. It also has various types of reels aside from the default six reels of the machine. And, of course, to play and win in the game, you need to land at least three matching symbols on adjacent reels.

There are 14 game icons or symbols in total, two of which are the wild and bonus symbols. The twelve others are the paying symbols in the game. Four of them are animal symbols, and they pay the most. There are also four gang posters and four poker symbols. Specifically, these symbols are:

  • Wolf
  • Doberman
  • Cat
  • Pug
  • Pest Control
  • Dirty Dawgs
  • Gritty Kitty
  • Pug Thugs
  • Letter A
  • Letter K
  • Letter Q
  • Letter J

Wager Limits

Although it doesn’t have a jackpot prize, you can win up to 10,000 times your bet with Nitropolis 2. However, your bet must be within the minimum and maximum wagers of 0.20 to 100. You can bet with these amounts or levels:

  • 0.20
  • 0.40
  • 0.60
  • 1.00

  • 10.00
  • 20.00
  • 40.00
  • 60.00
  • 100.00

Whichever you choose, it will be multiplied by the multiplier of the corresponding symbol and how many symbols you matched in each spin. A round automatically ends if there are no matching symbols but will continue to spin if you succeed in doing so.

Audio & Design

The audio and design of the game revolve around the concept of a dystopian place and post-apocalyptic world that has cats, dogs, and other species in it. Since Nitropolis 2 is a sequel to the original Nitropolis, the visuals are similar.

There are futuristic buildings and components in the background, while the slot machine itself looks like an actual machine. The background and the overall design matched the exciting and hypnotizing background music – EDM-like music with a robotic animal voice singing.

Nitropolis 2 Bonus Features

Nitropolis 2 Slot Bonus

The best features the Nitropolis 2 slot game offers are its bonus features, which include the Nitro Reels, Winning Respins, Nitro Boosters, Bonus round, and X-iter features. These are unique, but all have similar in-game goals – to increase your chances of winning and help you acquire a big payout.

Nitro Reels

This is one of the best keys for bigger winnings – the wildcard. Nitro Reels randomly land in each spin and cover two symbol positions. These can contain four, six, eight, ten, or 12 symbols, increasing the number of ways you can win.

Winning Respin

Whenever there’s a win with the Nitro Reels, the positions of all the same symbols in the Nitro Reels and Nitro Reels that are parts of the win will automatically respin. The other symbols will remain locked in place. And the respin is continuous until winning combinations land.

Nitro Booster

Nitro Booster

This is a new feature that’s not available in the original Nitropolis. Nitropolis 2 has eight different Nitro Booster features. These features are represented by additional symbols that appear in the feature reel on the topmost part of the machine, on top of the main reels.

These feature symbols modify the reels below them and include:

  • Pay Both Ways feature ‒ with this feature, winning combinations, and all wins are paid and effective from left to right and right to left.
  • All Wild feature – this leads to all the symbols in the Nitro Reels being wilds.
  • Respin feature – the bonus symbols and the Nitro Reels are locked while the other reels, including the feature reel, respin.
  • Nitro Upgrade feature – this means an upgrade is done to the Nitro Reels. More symbols are added under it.
  • All Match feature and Nitro Match feature – These mean that all the symbols in the Nitro Reel will match a symbol on the left reel.
  • All Premium feature ‒ All symbols in the Nitro Reel will only be high-value or premium symbols.
  • Nitro Wild feature ‒ Any Nitro Reel that lands on the same column will only contain wild symbols.

Bonus Game

The dog car is the only bonus symbol in the game. And to trigger and get a bonus game, you need to land at least three bonus symbols. And as the number of matching symbols increases, the number of awarded free spins also increases:

  • Three matching bonus symbols = Ten free spins
  • Four matching bonus symbols = 15 free spins
  • Five matching bonus symbols = 20 free spins
  • Six matching bonus symbols = 25 free spins

With the Bonus Game, all Nitro Reels will be locked in place and will remain in play for the remaining duration of the free spins. Moreover, Nitro Boosters are also allowed to land to increase the symbols in the Nitro Reels for more chances of winning.

X-iter Feature

This feature isn’t widely available and is only supported in some countries. With the X-iter feature, you can select from five various game modes. Here are the offers:

X-iter 15x BetEnsures the player a winning spin
X-iter 225x BetAwards three spins, including
a feature or bonus symbol on
every Nitro Booster position
X-iter 3100x BetA bonus game feature with ten
