Nitropolis 5 Overview

Nitropolis 5 is a slot from ELK Studios. This game serves as the conclusion to the “Battle for Nitropolis” storyline. Groups in the city come together to take back control. Earlier in the year, the “Battle for Nitropolis” series began, showing different groups growing tired of Sergeant Nitro Wolf’s actions. They saw the need to work together to reclaim their city. Previous games let players join attempts to outsmart Nitro Wolf. The story buildup over the first half of the year now reaches its final chapter. It is time to return to this city and find out what it offers now.

Nitropolis 5 Game Information

This game brings us to Nitropolis. This city’s economy centers around nitro-gas. Tall buildings with large screens showing Sergeant Nitro Wolf are visible behind the reels. A calm feel exists before starting the game, then the speed picks up with sound. The game works on most tablets, computers, and phones. Wins form with 3 or more matching symbols on adjacent reels starting from the far left. A mode called “Pay Both Ways” can be active, letting wins start from the far right reel as well. If you want to play slot games, this one presents a busy setting.

Low pay symbols are the J, Q, K, and A. A win of 6 matching pays 0.25X the bet. Medium pay symbols are the group logos: Rogue Rats, Pug Thugs, Gritty Kitty, and Dirty Dawgs. A setup of 6 matching pays 0.30X the bet. Highest pay symbols are the leaders of the four groups. A win of 6 matching pays from 1X to 3X the bet. A truck is the scatter symbol and can land as a super scatter symbol. This game has many symbol types, including wild, big, and nitro booster symbols during spins. Let’s learn how the special functions work.

Avalanche

When a winning setup forms, the avalanche function starts. Winning symbols disappear. New symbols drop into their spots. An extra row adds on, up to 8 rows on each reel. Any Nitro Reels and Nitro Multipliers that were part of the win restart. This avalanche session keeps going as long as new winning setups form.

Wild symbol

The wild symbol in this game helps make more winning setups. It replaces other paying symbols, but not scatter symbols.

Big Symbols

Larger symbols can appear on the reels during spins. They come in 2×2 and 3×3 sizes. One 2×2 symbol is like four regular symbols of the same type. If empty spots are below a large symbol, they fill with the same symbols shown on the large image.

Nitro Reels

Two kinds of Nitro Reels can show on the game field: regular and large. Regular ones take two spots; large ones take six. Regular Nitro Reels hold 4, 6, 8, 10, or 12 paying symbols at 1×1 size. Large Nitro Reels include 2, 3, 4, 5, or 6 paying symbols at 2×2 size. Scatter symbols can be on Nitro Reels, but only one per reel counts, regardless of its size.

Nitro Multiplier

This item shows with a value of 4X, 6X, 8X, 10X, or 12X. It multiplies all wins in view. It takes up two symbol spots. If several Nitro Multipliers are on the reels at the same time, their effect multiplies.

Nitro Booster

The Nitro Booster sits above the main reels. It can start 11 different bonus actions. Six of these affect the main reels, and five affect the Nitro Reels. These actions do the following:

Affecting Main Reels

Max Rows = Raises the number of reel rows up to 8.

Two Ways = Starts in the current round or remaining free spins. Wins can begin from both the far left and far right reels.

Dirty Dawgs = A random number of high value symbols change to Dirty Dawgs symbols.

Gritty Kitty = A symbol type is chosen for scatter pay. A scatter win can begin on any reel but must show on three different main reels.

Respin = When no new wins form, a respin starts. It keeps wild, scatter, nitro multiplier, and nitro reel symbols. Only one respin action can start at a time.

Boss Fight = With 3 boss fight coins, this action starts at the end of a free or regular spin. The Boss Fight shows a new 7×8 grid. Each spot is empty or holds a coin with a value. You get 3 shots. Hitting a coin collects it and resets shots to 3. A coin with the 50,000x max win can be won here. The action goes on until shots are used or the max win is hit.

Impact on Nitro Reels

Nitro Wild = Nitro Reels below the Nitro Wild symbol fill with wild symbols. If no nitro reels are below, the effect waits until it can be used or the round ends.

Nitro Upgrade = Nitro Reels located below increase their size meter and number of paylines. If no nitro reels are below, the effect waits until it can be used or the round ends.

Nitro Match = Nitro Reels below change to show the same symbol type found on the same or a neighbor reel to help form a win setup. If no nitro reels are below, the effect waits until it can be used or the round ends.

Rogue Rats = A random nitro reel moves to a new spot to make or extend an existing win setup.

Pug Thugs = A random number of nitro reels add to the main reels.

NPD Holding Cell

This action can start randomly during spins. A symbol type will be picked randomly. If the chosen symbol type is part of a win setup, it will stay in place and start a respin. Respin sessions continue as new symbols of the chosen type show or another NPD holding cell action starts. Held symbols will pay out when a new respin does not start.

Bonus Game

The Bonus Game starts with 3 or more scatter symbols. Based on the number of scatters that land (3, 4, 5, or 6), you get 8, 12, 16, or 20 free spins. If 3 or more scatter symbols land during the bonus session, you will get the same number of extra free spins. For a helpful slot rating, note the bonus structure.

During the bonus game, all nitro reels stay in place. The starting safety level is set at 4 rows. Each win raises the safety level by one row. Nitro reels can raise this level if they are higher up than a regular win. The max safety level of 8 rows can be reached during the session.

Super Bonus Game

If at least one of the scatter symbols is a super scatter symbol, the Super Bonus Game starts. This super scatter symbol can only land inside a nitro reel. Besides the features of the regular bonus game, the super bonus game begins with the max number of rows and activated Pay Both Ways. The NPD Holding Cell action will also be active with every free spin.

For direct entry to extra possibilities, you can use the feature buy option.

3X (Bonus Hunt) = The chance of starting the bonus game goes up more than four times.

10X (Gang War) = You get a spin where the nitro booster is filled with actions.

25X (NPD Forever) = The “NPD Holding Cell” action is guaranteed to start.

100X (Bonus Game) = The standard bonus game starts.

500X (Super Bonus Game) = The super bonus game starts.

F.A.Q.

What is the story behind the Nitropolis 5 slot?

Nitropolis 5 serves as the concluding chapter in the "Battle for Nitropolis" storyline developed by ELK Studios. This series depicts various groups within the futuristic city of Nitropolis growing increasingly dissatisfied with the rule of Sergeant Nitro Wolf. In this game, these different factions unite with the goal of reclaiming control of their city. The narrative builds upon the events of previous games published earlier in the year, where players could participate in attempts to outsmart the antagonist, Nitro Wolf. This final installment brings players back to the heart of the city to experience the culmination of this ongoing conflict and discover what rewards await those who succeed in the rebellion.

How does the Avalanche feature work in this game?

The Avalanche feature is triggered whenever a winning combination lands on the reels. Upon forming a win, the symbols involved disappear from the grid. New symbols then cascade down from above to fill the empty spaces. A key aspect of this feature is that each avalanche also adds an extra row to the reel setup, potentially increasing the number of rows up to a maximum of eight per reel. Any special symbols like Nitro Reels or Nitro Multipliers that were part of a winning setup will reset for the next drop. The avalanche process continues as long as new winning combinations are created by the cascading symbols, offering potential for multiple consecutive wins from a single spin.

What are Nitro Reels and Nitro Multipliers, and how do they affect wins?

Nitropolis 5 features two types of Nitro Reels: regular and large. Regular Nitro Reels occupy two symbol positions and can contain 4, 6, 8, 10, or 12 1x1 paying symbols. Large Nitro Reels take up six symbol positions and contain 2, 3, 4, 5, or 6 2x2 paying symbols. These reels increase the potential number of winning ways by displaying multiple symbols in a single space. Nitro Multipliers are special symbols that appear with values (4X, 6X, 8X, 10X, or 12X). When present, a Nitro Multiplier multiplies all wins in view. If multiple Nitro Multipliers land simultaneously, their multiplier values are combined multiplicatively, leading to significantly larger payouts for any wins. Scatter symbols can also appear within Nitro Reels.

Could you explain the Nitro Booster feature and its effects?

The Nitro Booster is a dynamic element located above the main reels that can activate one of 11 different bonus actions on any given spin. These actions are split into two categories: those affecting the main reels and those impacting the Nitro Reels. Actions affecting main reels include adding maximum rows, enabling Pay Both Ways wins, transforming symbols (Dirty Dawgs), creating scatter pays (Gritty Kitty), triggering respins on non-winning spins while holding certain symbols, or initiating the Boss Fight coin collection game. Actions impacting Nitro Reels involve filling them with wilds (Nitro Wild), upgrading their size and paylines (Nitro Upgrade), making them match adjacent symbols (Nitro Match), moving them for better wins (Rogue Rats), or adding new Nitro Reels to the grid (Pug Thugs). This feature adds significant unpredictability and potential for enhanced gameplay outcomes.

What is the difference between the Bonus Game and the Super Bonus Game?

The main difference lies in the starting conditions and additional features. The standard Bonus Game is triggered by landing 3 or more scatter symbols, awarding a number of free spins based on the number of scatters (8, 12, 16, or 20). During this bonus, all Nitro Reels remain locked in place for the duration, and a safety level for rows starts at 4, increasing by one with each win up to 8 rows. The Super Bonus Game is triggered when at least one of the initiating scatter symbols is a super scatter (which can only appear within a Nitro Reel). The Super Bonus Game includes all features of the standard Bonus Game but starts immediately with the maximum number of 8 rows active and the Pay Both Ways feature enabled from the first spin. Additionally, the NPD Holding Cell feature is guaranteed to be active on every single spin within the Super Bonus Game.

What is the Feature Buy (X-iter) option in Nitropolis 5?

The Feature Buy, also known as the X-iter menu, provides players with direct access to various game features for a specific cost relative to their bet size, bypassing the need to trigger them organically through regular spins. There are five distinct options available. For 3X the bet, you can buy a "Bonus Hunt" spin that significantly increases the chance of triggering the bonus game. Paying 10X the bet triggers a "Gang War" spin where the Nitro Booster above the reels is guaranteed to be filled with actions. A "NPD Forever" purchase for 25X the bet guarantees the "NPD Holding Cell" action on the resulting spin. For 100X your bet, you can directly buy entry into the standard Bonus Game. The most expensive option is 500X the bet, which guarantees entry into the highly volatile Super Bonus Game with its enhanced starting conditions.
