Nitropolis 5

Nitropolis 5, developed by ELK Studios, returns players to the vivid, dystopian world where gangs clash under the rule of the oppressive wolf regime. This slot game, part of a popular series, captivates with its compelling storyline, visually striking design, and interesting mechanics. Players can experience the ongoing saga of Nitropolis, where each spin reveals a part of a larger narrative.

Gameplay features and bonuses

Nitropolis 5 is a complex online slot game developed by the innovative ELK Studios. The base game features a straightforward layout with a grid of 6 columns, 4 rows, and 4,096 ways to win. However, with the game's unique features, the grid can expand to 8 rows. The game boasts a relatively low RTP of 94% and high volatility, creating an exciting playing experience.

Avalanche: Wins in this game are formed from left to right across consecutive reels. When a win is achieved, the contributing symbols disappear, allowing new ones to fall and potentially create additional wins. The grid expands by one row with each Avalanche, up to a maximum of 8 rows.

Special Symbols

• Wilds: These symbols substitute for all regular payout symbols, excluding Bonus and Super Bonus symbols.
• Big Symbols: Symbols can appear in three sizes—Standard (1×1), Super (2×2), and Mega (3×3), with each size covering equivalent symbol spaces on the grid.
• Bonus Symbols: These are manifested as Standard and Super Bonus symbols, aiding in the activation of the Bonus Game.
• Nitro Multiplier: Appearing in Nitro Reels, these symbols carry multipliers of 4x, 6x, 8x, 10x, and 12x, applied to all grid wins, irrespective of initial connections.

Nitro Reels: A unique reel type covering two spots on the grid, each Nitro Reel contains a random number of 1×1 symbols, ranging from 4 to 12. A larger, Big Nitro Reel can cover 6 symbols and includes 2 to 6 2×2 payout symbols. The number of ways to win adjusts based on the symbols contained within these reels. When part of a winning combination, Nitro Reels are held and respun in the next spin.

NPD Holding Cell: Positioned to the right of the grid, this feature triggers randomly on any spin, selecting a random symbol. If the chosen symbols contribute to a win, they are retained on the reels, along with Scatter symbols and Nitro Multipliers. This process continues as long as additional symbols of the selected type contribute to the win or another NPD Holding Cell feature activates. This feature can retrigger multiple times within a round and potentially during an ongoing NPD Holding Cell feature, increasing the number of symbols affected.

Nitro Booster: Positioned above the grid, this display features three flippers that can activate special enhancements before the reels stop. There are 11 features in total – 6 impacting the main reels and 5 affecting the Nitro Reels.

Main Grid Features

• Max Rows: Expands the grid to its maximum capacity.
• Both Ways: Lets the game pay from both right to left and left to right; if triggered during the bonus round, it remains active throughout.
• Respin: Activates once no further wins occur; Nitro Reels, Nitro Multipliers, Scatters, and Wilds remain in place for the Respin.
• NPD Police Report – Dirty Dawgs: Replaces a random selection of high-value symbols with the Dirty Dawgs symbol.
• NPD Police Report – Gritty Kitty: Selects a random symbol for Scatter Pay evaluation, which requires the symbol to appear on at least three reels for a payout. When combined with Both Ways, the feature pays out twice.

Nitro Reels Features

• NPD Police Report – Rogue Rats: Randomly places Nitro Reels on the main grid.
• NPD Police Report – Pug Thugs: Relocates a randomly selected Nitro Reel to a new position.
• Nitro Wild: Converts all below Nitro Reels into Wild symbols.
• Nitro Upgrade: Increases the size indicator of all Nitro Reels below it.
• Nitro Match: Matches all Nitro Reels below it with a symbol on the same or adjacent reel.

Boss Battle: Triggered when three Nitro Boosters display the Boss Battle symbol at the end of a spin, this feature transforms the grid into a 7×8 layout populated only by coin values and Max Win symbols. The round commences with three Respins, resetting with each landed symbol and decrementing if none are landed. The round concludes either when no Respins remain, or the Max Win is achieved.

Bonus Game: This is essentially a Free Spins round, activated when 3, 4, 5, or 6 symbols land, awarding 8, 12, 16, or 20 Free Spins respectively. The Super Bonus Game triggers if any of the Bonus symbols is a Super Bonus one, which appear exclusively within Nitro Reels. Landing 3 or more Bonus symbols during the round grants additional Free Spins, just as in the initial trigger.

The dynamics of the round mirror those of the base game but with the addition of Nitro Reels, which remain on the grid regardless of any wins. A safety level starting at 4 rows is introduced, with each winning spin increasing this level to a maximum of 8. The following Free Spin begins from the newly established safety level.

If activated during the game, the regular round deactivates features like Both Ways and Max Rows; however, the Super Bonus round maintains these features active throughout, along with the NPD Holding Cell feature, enhancing the potential for substantial wins.

X-iter Options: Players can buy direct access the game's bonus features:

• Super Bonus: 500x the bet to activate.
• Bonus: 100x the bet.
• NPD 4EVA: 5x the bet for a round that triggers the NPD Holding Cell.
• Gang Warfare: 10x the bet for a spin fully loaded with features.
• Bonus Hunt: 3x the bet for a spin that is four times more likely to activate the bonus game.
