Nitropolis 4 Online Slot

The dystopian animals are back in the action-packed Nitropolis 4 online slot. This entry in the hugely successful series from ELK Studios plays out on 5 reels, 4 rows, and 4,096 ways to win. It’s a high volatility game with an average return to players percentage of 94%, and maximum wins of 50,000x the stake are possible.

Features include cascading symbols and expanding reels on every win. Nitro Reels can hold up to 12 symbols, while Nitro Multipliers increase wins by a maximum of 12x each, and Super Symbols can fill 2x2 or 3x3 blocks at a time. There are 8 random modifiers available, such as a win both ways mechanism, symbol upgrades, and matched reels.

On top of this, Nitropolis 4 has a free spins feature with locked Nitro Reels and reels remain expanded throughout. You can unleash the action on PCs or mobiles at the best Slot Sites.

Like others in the series, Nitropolis 4 features cartoon pets, such as a crazy pug, sneaky cat, and tough Doberman. These characters are now working on an oil rig and share the reels with gang signs, such as Pug Thugs, and Gritty Kitty, plus playing card symbols, and a floating mine. The soundtrack is a bizarre mix of explosions, voice-overs, industrial noise, and an electronic tune that’s just about audible above the racket.

It looks great on PCs and mobiles running the Android, iOS, or Windows operating systems when playing on your chosen Betting Apps. The control options are the same across any device, with a tap on the pile of coins all that’s need to reveal bet options from 0.20 to 50.00.

Click the 3 lines button to open a paytable. It has further details on the many bonus features, plus a breakdown of symbol values. There’s a starting point of 4,096 ways to win and you need to match symbols across reels from the left, with the most valuable Doberman worth up to 3x the stake.

The mine wild symbol acts as others if needed and pays the same as the Doberman. An Avalanche system removes winning symbols and allows the ones above to drop down. Avalanches repeat if they form a new win, and an extra row appears above on each, to a maximum of 4 additional rows.

Nitro Reels and Nitro Multipliers can land at any point. Nitro Reels hold 4, 6, 8, or 12 matched symbols, one above the other, while Nitro Multipliers hold values of 4x, 6x, 10x, or 12x. Any win with a Nitro Multiplier gets the corresponding value applied and multiple examples combine their values.

Super and Mega symbols of 2x2 and 3x3 size can appear at any point, and there are 8 different Nitro Boosters that can activate at random. These include Redrops that lock bonus symbols onto the reels as others drop away, a Both Ways feature where you win from combinations starting on either side, and random Nitro, Multiplier, or Upgrades. Random symbols could vanish in the Garbage Collect modifier and the Nitro Match fills 2 reels with the same symbol mix.

If 3, 4, 5, or 6 Bonus symbols appear at once, or over the course of an Avalanche series, you get 8, 12, 16, or 20 free spins. Any Nitro reels remain active for the rest of the feature, and if reels expand, they remain expanded. You can retrigger the free spins and if a Super version of the bonus symbol starts the spins, the reels are 8 rows high, with a win both ways mechanism from the start.

The maximum 50,000x win is worth 2,500,000.00 at the highest bet of 50.00 – comparative with some Jackpot Slots returns. It’s a high volatility game where a relative infrequency of wins can be off-set by generous prizes. However, the return to players percentage of 94.00% is well below the 96.00% or more that we expect from highly volatile games.

The low returns are perhaps the biggest issue here, but this aside, Nitropolis 4 is a fantastic game. The multiple features could be too much for inexperienced players though.

Stacked symbols, multipliers, increasing ways to win, random modifiers, and free games are among the fantastic extras that can help you towards big wins. It also looks great across PCs and mobiles, with the hilarious characters all dressed for their jobs on the oil rig.

If you enjoy games with lots going on, and plenty of humour, be sure to join the cartoon pets on their latest adventure as you play the Nitropolis 4 slot at our recommended Casino sites.
