Nitropolis 3 Game Overview

Nitropolis 3 is a game from ELK Studios. It continues events in the world of Nitro gangs. Previous games, Nitropolis and Nitropolis 2, took place in a city with crime. Sergeant Nitro Wolf tried to restore order but went south looking for calm. The Nitro gangs followed, and the search for peace remains. Those familiar with earlier games know about the impact of Nitro Reels during gameplay. This payout function is present in this release. Many elements are similar, but key improvements appear. For example, the top win changed from 10000x to 50000x the bet. Let’s review what else this slot offers.

Nitropolis 3 Game Data

The game design shows a future setting. We follow characters who moved south from Nitropolis city. Behind the reels, a beach appears with a chair and umbrella. A large barrel with toxic material sits on the right. This game operates on all devices: tablets, computers, and mobile phones. Wins occur when 3 or more matching symbols land on neighbor reels, starting from the far left. With the Both Ways function active, symbol groups can also start from the far right reel.

Nitropolis 3 Game Functions

What is the maximum win?

The highest possible win is 50000 times the bet amount.

What functions are available?

The game includes: Wild Symbol, Redrop, Both Ways, Avalanche, Big Symbols, Nitro Reels, Bonus Game, and X-iter.

Wild Symbol

The Wild symbol helps create more winning sets by substituting for other symbols, except scatter, super scatter, Redrop, Both Ways, and Nitro symbols. If a Wild appears within a feature frame and contributes to a win, it changes into a Nitro feature symbol.

Redrop

If a winning symbol group does not form, this function may activate. All Nitro symbols and scatters remain fixed, and other positions on the reels spin again.

Both Ways

When this symbol appears, winning groups form from left to right and right to left. This function stays active during the entire cascade process.

Avalanche

When a winning group forms, the Avalanche function starts. Winning symbols vanish from the reels. New symbols drop into their spots, and an extra row adds, increasing rows up to 8. If Nitro Reels are part of a winning group, they respin with the next symbol drop. This process continues as long as new winning groups appear. Check the slot rating for more details.

Big Symbols

During spins, symbols may appear in different sizes: 1×1, 2×2, 3×3, or 4×4. For example, if a 3×3 symbol lands, it takes up space equal to 9 normal symbols. Low, mid, and high value symbols, as well as Wild symbols, can be part of these larger images.

Nitro Reels

During spins, small Nitro Reels may appear, covering 2 symbol spots. They hold 4, 6, 8, 10, or 12 matching 1×1 symbols at random. Large Nitro Reels may also land, containing 2, 3, 4, 5, or 6 matching 2×2 symbols.

Small Nitro Reels can hold super scatter symbols. Each super scatter counts as one 1×1 symbol, regardless of the number shown on the reel. The number of winning ways returns to the earlier amount when the super scatter vanishes. If Nitro Reels are part of a win, they respin with the next symbol drop.

Nitro Features

The game has three distinct Nitro functions. They may become active during gameplay after symbols settle but before wins are paid. After a Nitro function starts, it may randomly become a Wild symbol. If this Wild helps a winning group, it changes back into a Nitro function. These functions are called Nitro Match, Nitro Upgrade, and Nitro Wild.

Nitro Match = When a Nitro Match symbol lands, all Nitro Reels on the same and neighbor reels will match an adjacent pay symbol.

Nitro Upgrade = When a Nitro Upgrade symbol lands, Nitro Reels on the same and neighbor reels will improve, and extra symbols will add to the Nitro Reels.

Nitro Wild = When a Nitro Wild symbol lands, all symbols within Nitro Reels on the same and neighbor reels will turn into Wild symbols.

Bonus Game

The Bonus Game starts when 3 or more scatter symbols appear. Based on the number of scatters (3, 4, 5, or 6), you get 8, 12, 16, or 20 free spins. More free spins are possible during the Bonus Game. Any Nitro Reels that land stay fixed for the remaining spins. A safety level applies, where each winning spin adds 1 row, up to a maximum of 8 rows, and these rows do not reset between spins. If the bonus game starts with a mix of normal and super scatter symbols, you access the Super Bonus Game. Here, the Both Ways mode is always active, and you begin with 8 rows. Consider where to play slot games like this.

X-iter Feature

The X-iter mode lets players activate specific game functions instantly for an added cost. Here are the choices:

2X (Bonus Hunt) = The chance of starting the bonus game increases more than two times.

10X (Nitro Reel) = Guarantees a large Nitro Reel lands.

25X (Nitro Match & Both Ways) = Guarantees the Nitro Match and Both Ways functions activate.

100X (Bonus Game) = Starts the bonus game with sticky Nitro Reels.

500X (Super Bonus Game) = Starts the super bonus game with sticky Nitro Reels and the Both Ways function.

F.A.Q.

What is the theme and setting of the Nitropolis 3 slot game?

Nitropolis 3 is the third installment in a series from ELK Studios that continues the saga of the Nitro gangs. While the previous games were set in the crime-ridden city of Nitropolis, this release sees the characters venture south, reportedly in search of calm. Sergeant Nitro Wolf, who previously tried to restore order in the city, has also headed south. The game's visual design reflects this change in location, depicting a future setting with a beach in the background, complete with a chair, umbrella, and a barrel of toxic material, suggesting a not-so-peaceful coastal retreat. This new environment serves as the backdrop for the familiar gameplay mechanics and introduces new elements while maintaining the series' core identity.

How do winning combinations work, and what is the "Both Ways" function?

In Nitropolis 3, wins are typically formed by landing three or more matching symbols on adjacent reels, starting from the leftmost reel. These winning symbols must be consecutive across the reels. The game also features a special "Both Ways" function. When this function is active, it expands the ways to win by allowing winning groups of symbols to be formed starting not only from the far left reel but also from the far right reel. This essentially doubles the potential directions for forming wins. The "Both Ways" function remains active throughout the entire cascade process initiated by the Avalanche feature, potentially leading to more frequent payouts on subsequent symbol drops within a single spin.

Can you explain the Nitro Reels feature and the different types?

Nitro Reels are a distinctive mechanic in Nitropolis 3 designed to significantly increase the number of potential winning ways. There are two main sizes of Nitro Reels. Small Nitro Reels occupy the space of 2 normal symbol spots vertically but contain multiple smaller 1x1 symbols, randomly holding 4, 6, 8, 10, or 12 identical symbols. Large Nitro Reels are bigger, covering a larger area horizontally and vertically, and contain multiple 2x2 symbols, specifically 2, 3, 4, 5, or 6 matching ones. These reels are crucial because they effectively place many symbols into a single reel position, drastically boosting the ways calculation. If a Nitro Reel is part of a winning combination, it doesn't disappear during the Avalanche; instead, it respins with the next symbol drop to potentially form new wins.

What happens when the Avalanche feature activates?

The Avalanche feature in Nitropolis 3 is triggered whenever a winning combination lands on the reels. Once a win is formed, the symbols involved in that win vanish from the grid. The empty positions are then filled by new symbols dropping down from above. A key effect of the Avalanche is that each time a winning group forms and triggers it, an extra row is added to the top of the reel grid. This process can continue repeatedly as long as new winning combinations are created by the symbols dropping into place, expanding the number of rows up to a maximum of 8. This cascading wins and expanding rows mechanic allows for multiple potential wins from a single initial paid spin.

How is the Bonus Game triggered, and what are its main benefits?

The Bonus Game in Nitropolis 3, which awards free spins, is triggered by landing three or more scatter symbols anywhere on the reels in the base game. The number of free spins you receive depends on how many scatters land: 3 scatters award 8 free spins, 4 award 12, 5 award 16, and 6 award a generous 20 free spins. A significant benefit during the Bonus Game is that any Nitro Reels that appear on the reels become "sticky," meaning they remain fixed in their positions for the entire duration of the remaining free spins. Additionally, a safety level is active, where each winning spin adds one row up to a maximum of 8, and these increased rows do not reset between free spins, maintaining a larger grid for more potential wins.

What is the X-iter feature and what options does it offer?

The X-iter feature in Nitropolis 3 is a unique mechanic that allows players to bypass standard gameplay and instantly trigger specific game modes or features for a predetermined cost, which is a multiplier of their base bet. It offers several options to tailor the gaming experience. These include a 'Bonus Hunt' (2X bet) that significantly increases the chance of triggering the bonus game; a 'Nitro Reel' guarantee (10X bet) ensuring a large Nitro Reel lands; a 'Nitro Match & Both Ways' guarantee (25X bet); a direct trigger to the 'Bonus Game' with sticky Nitro Reels (100X bet); and a direct trigger to the enhanced 'Super Bonus Game' with sticky Nitro Reels and the Both Ways function always active (500X bet). This feature provides players with strategic betting options to access desired game mechanics instantly.
