    How to Play Nitropolis 4 Slot

    Once you are prepared to watch the 4 reels with 4 rows spin, you should press the blinking curved arrow in the lower-right corner. This is the play button of the Nitropolis 4 slot game. Of course, you can also automate the process thanks to the auto arrow on the right side. This simple feature enables you to launch 10 to 100 automated rounds. As for the bet size, you can use the coins on the left. Every user has twelve options, starting with €0.2 and ending with €50.

    When players press the three lines, they will open a new window. The paytable is the first thing they will see on the screen. However, you can also use the settings/gear icon to regulate the general settings and the info sign to read the rules. The promotions sign will reveal if there are any promotions associated with the game in the casino where you are playing.

    Symbols and Payouts

    We counted sixteen symbols in the Nitropolis 4 slot. That’s an impressive collection, especially when we know four have unique properties. The standard ones work in the same way – they provide rewards to all players with 3 to 6 identical ones on adjacent reels. Our Nitropolis 4 slot review will highlight the potential payouts you can expect here.

    The tradition of the use of playing card values continues. So, the first four icons look like playing card values from Jack to Ace and provide prizes worth 0.1 to 0.3 times the player’s stake. After that, we have the four Gang Logos (Rogue Rats, Pug Thugs, Gritty Kitty, and Dirty Dawgs) promising 0.15 to 1 time the bet. Finally, we have the human-like animal characters: the Rat, the Pug, the Cat, and the Dog. They can help users win between 0.5 and 3 times the stake, and the Dog is the top-paying icon of the game.

    None of the symbols with special properties (Nitro Multiplier, Wild, Bonus icon, or Super Bonus icon) don’t provide payouts in this way. You don’t have to play for real money to witness these payouts because even a Nitropolis 4 demo, which is available at GoodLuckMate, can help you with that. However, the demo mode will improve your virtual balance, which doesn’t have real value.

    Nitropolis 4 Bonus Features

    Even experienced players will be impressed by the number of Nitropolis 4 bonus features. We’re talking about common and innovative extras in one place.

    Nitro Booster

    Players will spot two TV displays above the gameboard. They are usually blank, but randomly, they can provide Nitro Booster modifiers. More precisely, you can expect 8 extras that can help you in different ways: a partial respin (Redrop), wins pay both ways, grid expansion, symbol removal, an addition of a Nitro Reel, a Wild Nitro Reel, a Nitro Reel’s value boost, or a Nitro Match for a guaranteed win.


    The participating icons are destroyed whenever players hit a winning combination in the base game or the bonus game. They allow new symbols to drop and provide an extra row of symbols (up to 8 rows). The Nitro Reels and Nitro Multipliers contributing to the winning combinations, respin.

    Big Symbols

    Randomly, on any spin or Avalanche, you can hit Super or Mega symbols – 2x2 or 3x3 in size, respectively. Only standard and Wild icons can appear as big symbols. As for the Wilds, they look like Bombs and count as standard symbols to help users form winning combos.

    Nitro Reels and Nitro Multiplier

    Randomly, you can land Nitro Reels that cover two positions on the layout and can appear on any reel. These special reels include 4 to 12 standard icons. We also have Big Nitro Reels that fill six positions and include 2 to 6 2x2 (Super) standard symbols.

    In addition, players can land Nitro Multipliers which also take two positions and count as a single icon. As the name suggests, they multiply the wins. The multiplier values they carry are between x4 and x12. These multiplier values are multiplied by each other when there are two or more Nitro Multipliers on the reels.

    Bonus Game/Free Spins

    Players should wait for three to six Bonus icons anywhere on the reels to launch 8 to 20 Nitropolis 4 free spins. During this round, the Nitro Reels are sticky and remain in their positions until the end. In addition, each winning round boosts the so-called safety level by one row. The game starts with the actual safety level when the next free spin is activated.

    Besides the Bonus icon, we have a Super Bonus icon. When you have a combo of three or more Bonus and Super Bonus symbols on the reels, you access the Super Bonus Game, which includes the maximum number of rows, and both ways pay.

    X-iter/Bonus Buy Feature

    X-iter represents ELK Studios’ bonus buy feature. Players have several options to choose from, including activating a round of free spins by paying 100 times their current bet. You can see how this feature works even during Nitropolis 4 free play.

    RTP & Volatility

    Here comes the last part of our Nitropolis 4 slot review, which focuses on two technical things. To start with, we will note that the Nitropolis 4 RTP is94%, slightly below average. Second, the provider scored the volatility of this release an 8 out of 10, which indicates that this is a highly volatile slot game.
