Dirty Dawgs
Still SwingingThe dog clan didn't get the memo about laying low. Grenades, muscle and a shotgun-toting crew, still causing chaos across the dystopian city while the heat closes in.
Sergeant Nitro Wolf locked up the Rogue Rats — so part two has one fewer gang and one big new reel.

Nitropolis 2 returns 95% and caps at 10,000x. It's the sequel that adds a whole new mechanic instead of just reskinning the first. That mechanic is the Nitro Booster.
ELK dropped this one in April 2021, barely five months after the original. Fast, even for them. The story picks up with Sergeant Nitro Wolf cracking down on the gangs. He's already banged up the Rogue Rats, so this time it's dogs, cats and pugs left scrapping over the Nitro.
The big change sits above the grid. A Nitro Booster reel now feeds features onto the reels below — wilds, upgrades, premium symbols. Combined with the returning Nitro Reels, the ways to win balloon to a genuinely absurd 191,102,976. That more than doubles the first game's ceiling.
Honestly? It feels busier than the original, in a good way. There's more going on every spin, more little modifiers firing. The trade-off is the RTP slipping to 95%, and the volatility staying brutal at 8 out of 10. You'll hit something roughly one spin in five, but the size of those hits swings wildly.
Three clans left standing
Sgt Nitro Wolf has thrown the Rogue Rats in a cell, so Nitropolis 2 is down to three gangs on the streets — with the Sergeant himself now hunting whoever's left.
Gritty Kitty
In the ShadowsThe cats slipped the Sergeant's first sweep by doing what they do best: staying invisible. Silent, precise and always one alley ahead of Pest Control.
Pug Thugs
Still BuildingThe engineers keep the Nitro flowing whoever's in charge. Goggles down, tools out, rigging the pumps and the getaway cars for whichever gang is still standing.
Sgt Nitro Wolf
The LawNew to the story and already a problem. Sgt Nitro Wolf runs Pest Control, a one-wolf crusade to scrub the gangs off the map. He bagged the Rats first. He's coming for the rest.
Features that decide your session
Skip the lore for a second. These are the mechanics that move money in Nitropolis 2, in the order they matter.
New
Nitro Booster reel
A feature row above the grid. Symbols land there and modify the Nitro Reels below — Nitro Wild, All Wild, All Premium and more. It's the headline addition over the first game.
Core
Nitro Reels
Same engine as before. Tall tiles holding 4 to 12 symbols, each one widening the ways to win. Land enough and you're in the tens of millions.
Base game
Winning respins
Every win respins the symbols, Nitro Reels and Boosters involved. Chains keep going while new wins appear. Booster features stick to their reel during the sequence.
Buy
X-iter bonus buys
Five options, from a 5x guaranteed win spin up to a 500x Super Bonus that starts with twelve Nitro Reels in play. RTP stays at 95% across all of them.

RTP, max win and who it suits
At 95%, the RTP dips below the original's 96.1%. Not a dealbreaker, but worth knowing. You're paying a little extra house edge for the extra chaos the Booster brings.
Max win holds at 10,000x, same as part one. So the ceiling didn't grow — the ways to win did. That's a subtle point people miss. More ways doesn't mean a bigger top prize; it means more frequent small-to-mid combinations.
Who's it for? Fans of the first game who want more moving parts. If the original felt a touch simple, this is the fix. New players might find it noisy — start on the demo and let the Booster make sense before you deposit.

The Booster reel makes this. So much more going on than the first one. Landed All Premium once and it turned a nothing spin into a proper win.

Prefer the sequel's pace, but the 95% RTP is noticeable over a long session. Still a banger. That soundtrack though, it's relentless.

Bought the 500x super bonus a couple of times. Twelve reels from the start is wild. Big swings — one paid huge, one flopped. High vol as advertised.

Demo is great for learning the Booster before risking anything. Once it clicks, it's hard to go back to part one. Bit chaotic at first mind.
Playing Nitropolis 2 without losing your head
Nitropolis 2 throws more at you than the first game, so pace yourself. The Nitro Booster row means there's often something firing on every spin, which is exciting but also easy to misread. Spend a few demo rounds just watching what the Booster does before you care about the money.
The core lesson carries over from part one: the bonus is where it counts. Nitro Reels lock for the whole free spins round, and with the Booster stacking wilds and upgrades on top, that's where the 191 million ways actually open up. Base game keeps you ticking; free spins pay the rent.
X-iter gives you five buy options here, from a cheap 5x guaranteed win up to the 500x Super Bonus that starts with twelve Nitro Reels in play. That top buy is the dream scenario, but it's a big stake on a volatile game. Only ever buy what you'd be comfortable losing on a single spin.
RTP sits at 95%, a touch below the original but still reasonable for the series. Keep stakes modest, let the Booster do its thing, and don't chase losses after a cold streak. The volatility rating of 8 out of 10 isn't a suggestion, it's a warning to manage your bankroll like you mean it.
- Watch the Booster first — learn what each modifier does in the demo.
- Free spins carry the game — locked Nitro Reels plus Booster is the payday.
- Buys are single big bets — the 500x Super Bonus is a gamble, not a guarantee.
- Respect the 8/10 volatility — small stakes survive the dry spells.
