Nitropolis 4 continues the saga of the nitro gangs in an underwater quest developed by ELK Studios. The story began in 2020 with the introduction of the Dirty Dogs, Gritty Kitties, Pug Thugs, and Rogue Rats – gangs fighting for valuable green nitro. As this resource became scarce, tensions escalated. Sergeant Nitro Wolf entered the picture in Nitropolis 2, attempting to restore order. When his efforts proved challenging, Mr. Nitro Wolf escaped to warmer climates in Nitropolis 3, seeking peace. However, the gangs followed him, reigniting their rivalry. Now in Nitropolis 4, the gangs take their quest underwater in search of treasures beneath the surface.

What features are available in Nitropolis 4 slot?
The game includes numerous features: Wild Symbol, Avalanche, Big Symbols, Nitro Reels, Nitro Multiplier, Nitro Booster, Bonus Game, and X-iter.
The wild symbol substitutes for all other symbols except scatters, facilitating more winning combinations.
When a winning combination appears, the Avalanche feature activates. Winning symbols disappear from the reels, and new symbols fall into their place. Each Avalanche adds an extra row, increasing the number of rows on each reel up to eight, thus enhancing the number of potential winning combinations. Nitro Multipliers and Nitro Reels involved in winning combinations restart. The Avalanche continues as long as new wins form. The total win pays out when no further combinations occur.
During reel spins, enlarged symbols sized 2×2 or 3×3 may randomly appear. A 3×3 symbol equals nine regular symbols of the same type. These big symbols can be low-paying, medium-paying, high-paying, or wild symbols.
Nitro Reels occupy two symbol positions and contain 4, 6, 8, 10, or 12 paying symbols sized 1×1. You can also get Big Nitro Reels, which occupy 6 symbol positions and contain 2, 3, 4, 5, or 6 paying symbols sized 2×2. Nitro Reels can include super scatters, which only appear on them. Each super scatter on a Nitro Reel counts as one 1×1 symbol.
This symbol occupies two positions and multiplies all wins in view, while counting as a 1×1 symbol. It can appear with values of 4X, 6X, 8X, 10X, or 12X, and its effect multiplies if several Nitro Multipliers appear on screen simultaneously.
The game features 8 different Nitro Boosters that add features to the main reels. Here are their descriptions and effects:
Respin = All scatter symbols and Nitro Reels remain, while other symbols get removed. Then a respin occurs, with new symbols filling the empty positions.
Both Ways = Wins form both from left to right and right to left.
Garbage Collection = Symbols get randomly selected and then removed, activating the Avalanche feature.
Max Rows = Expands the reels to the maximum of 8 rows.
Nitro Drop = A random-sized Nitro Reel gets placed on the reels, replacing symbols where it lands.
Nitro Wild = An existing Nitro Reel fills with wild symbols. If no Nitro Reel exists, the feature is saved until one appears or the bonus game ends.
Nitro Upgrade = Nitro Reels on the same and adjacent reels get upgraded, with additional symbols or multipliers added. If no Nitro Reel exists, the feature is saved until one appears or the bonus game ends.
Nitro Match = An existing Nitro Reel matches with a visible symbol, then fills with that symbol type to create a win. If no winning match is possible, the selected Nitro Reel matches with an adjacent one. If that’s not possible, it matches with the highest-value symbol on adjacent reels. If no Nitro Reel exists, the feature is saved until one appears or the bonus game ends.
When 3 or more scatter symbols appear, the bonus game activates. Depending on the number of scatters (3, 4, 5, or 6), you receive 8, 12, 16, or 20 free spins respectively. During the bonus game, additional free spins can be earned, with the number of spins per scatter symbol being the same as during activation. All Nitro Reels that appear remain in place until the end of the bonus game. If the bonus game activates with at least one super scatter symbol, the super bonus game launches with Both Ways and Max Rows modes activated.
Each new free spin with a win increases the safe level by 1 row. The subsequent free spin always starts with the number of rows achieved at the safe level.
For quick access to additional possibilities, the X-iter mode can be used. The following options are available:
2X (Bonus Hunt) = Participate in a spin with doubled chance of activating the bonus game.
10X (Nitro Booster) = A spin where the Nitro Booster provides 2 features when activated.
25X (Super Spin) = A spin with Max Rows and Both Ways features activated.
100X (Bonus Game) = Launch the standard bonus game.
500X (Super Bonus Game) = Activate the enhanced bonus game with Both Ways and Max Rows features.
Nitropolis 4 takes the established franchise underwater, adding new dimensions to the gameplay while retaining the core mechanics fans appreciate. With its potential for massive wins up to 50,000x your stake, numerous features including Nitro Reels and multipliers, and the engaging storyline of the nitro gangs, this slot offers hours of entertainment. The X-iter function provides shortcuts to key features for players who want to jump straight into the action.
