Nitropolis 3 Theme

With a post-apocalyptic theme, as mentioned, the Nitropolis 3 slot game is the third game in the series after Nitropolis and Nitropolis 2. According to the story, the Nitro gangs were overpowered by Sergeant Nitro Wolf and were left with no choice but to jump into their trusty blimp and escape the city of Nitropolis. To continue their lifestyle, they have headed south towards a tropical beach with Nitropolis not too far behind. The backdrop features a deck chair, palm trees, a beach umbrella, a lifeguard’s hut and a few nuclear waste barrels. The game features an upbeat soundtrack with a more cheerful feel compared to the ones featured in the previous instalments, with comical animal sounds in between.

Symbols and Payouts

The slot comes with a paytable featuring twelve symbols. Although they appear different and their number is high, you can win with them the same way, i.e., by landing three to six identical symbols on adjacent reels. On the six reels of the slot, you will find various symbols. The first four are active and denoted by playing card additions with low-value red A, violet K, acid-green Q, and blue J royals. Next, come the medium value symbols, which are varying patches. These symbols include the logos for the Rogue Rats, the Pug Thugs, Gritty Kitty, and the Dirty Dawgs. Each division needs its own representative, of course.

The chief of the four clans symbolises the higher-paying symbols. Ascending in value, you will find the Rat Boss, the Pug Boss, the Kitty Boss, and the Dawg Boss. The Dawg Boss acts as the highest paying symbol, offering 1.5, 3, 4, or 5x your stake for 3, 4, 4, or 6 winning combinations. A wild symbol, denoted by a toxic sign and a poisonous-looking cocktail, replaces all the symbols except for the bonus and super bonus, redrop, both ways, and Nitro feature symbols.

Nitropolis 3 Bonus Features

Nitropolis 3 features eleven bonus features. With an avalanche feature and an increasing number of ways/rows to win, there are big symbols as well as Nitro Reels. Nitro Reels add additional 1x1 or 2x2 symbols that can boost the number of ways to win up to a million. With Nitro features improving your gameplay experience, free spins also cause the number of ways/rows to win to increase. The Super version lets you play the maximum 8 rows, and both ways pays. Below are the bonus features discussed in detail:

Avalanche Feature

The Avalanche feature is activated when you land a winning combination. All symbols in the winning combination explode, leaving room for new symbols to drop from the top. An extra row of symbols is added during this time, which continues to happen until the maximum of eight rows is visible. The more rows you get, the more ways the game offers to win, going up to 262,144 ways. Another winning combination can set off another avalanche, which continues until there are no more ways to win. The avalanche feature then continues you are left with no more winning combinations. After this feature round ends, you play on the default area, i.e., 6 reels and 4 rows with 4096 ways to win.

Big Symbols

All symbols may land in different sizes during your spins, i.e., 1x1, 2x2, 3x3, or 4x4. For instance, if you land a 4x4 Big symbol on the reels, it will be equal to 16 symbols. In another example, landing a 3x3 symbol will be equal to 9. This symbol increases your chances of landing a win. Other than that, the low, medium, high, and wild symbols may land within these big symbols.

Nitro Reels

Similar to the previous Nitropolis slot games, this instalment also has a Nitro Reels feature. While spinning, you can land small Nitro Reels that cover 2 symbol positions. These include 4, 6, 8, 10, or 12 1x1 paying symbols. You may also land big Nitro Reels, which contain 2, 3, 4, 5, or 6 of the same type of symbols where the symbols equal 2x2.

Once the super scatter symbol finally spins out, the number of ways to win will return to the previous amount. When a win consists of Nitro Reels, they respin to the incoming avalanche. Essentially, this offers more ways to win. You get up to a million ways to win. Furthermore, you can see the various ways to win above the reels for every spin.

Nitro Features

You can set off various Nitro Features during the game, where all the landed symbols activate them – but before the payout. Once a Nitro feature has been activated, it may turn into a wild. If this wild comes with a win, it will again turn into a Nitro feature. Below is some information on all of them.

Redrops: Redrop symbols cause the bonus and Nitro feature symbols to stick, while the Nitro Reels respin.

Both Ways: All the player’s active winnings are paid from left to right and right to left (double payouts).

Nitro Match: Once the Nitro Match symbol lands, all the Nitro Reels on the same and the adjacent reels are matched with an adjoining paying symbol.

Nitro Upgrade: Once the Nitro Upgrade symbol lands, the Nitro reels, which are found on the same and adjoining reels, upgrade, and additional symbols are added to the Nitro Reels.

Nitro Wild: Once the Nitro Wild symbol lands, all symbols in the Nitro Reels on the same and adjoining reels get replaced by wilds.

Bonus Game

You can activate the Bonus Game feature by landing 3, 4, 5, or 6 Blimp Bonus Scatters. This offers 8, 12, 16, 20 free spins in that order. You can reactivate additional free spins during this game, and all Nitro Reels become sticky throughout this feature. They stack on top of one another whenever a new Nitro Reel appears. You can also participate in a Safety Level Feature where each winning spin causes the rows to increase by one, where they can go up to 8 rows and not reset in between the spins. This means the ways to win/number of rows will not drop below the “safety” level.

With a retrigger for up to 40 free spins available, activating the Bonus Game feature via the Blimp Bonus Scatters and the Blimp Bonus Scatters combined activates the Super version. This significantly improves your payout potential since you can play on 8 rows with the Both Ways feature activated.

2X (Boosted Bonus Chance): This more than doubles your chances of activating the bonus game.

10X (Big Nitro Reel): This guarantees 1 spin with a big Nitro Reel.
