Pug Thugs of Nitropolis: Slot Overview

After clawing our way through animal-packed slots like Gritty Kitties, Dirty Dawgs, and Rogue Rats, it’s finally the Pug Thugs’ turn in the spotlight. The game is Pug Thugs of Nitropolis, and it serves as ELK Studios’ last build-up release before they unleash Nitropolis 5. Will it hit like an atom bomb? If the earlier entries are anything to go by, then yes—it should be a treat. There was some expectation that ELK Studios might dial things back for slots focused on a single clan, but that hasn’t happened; each one has been loaded with strong gameplay ideas without cutting corners on presentation. Add a pug’s natural charm, and the ingredients look right for another dependable Nitropolis entry.

Up to now, Rogue Rats of Nitropolis was arguably the most mechanically adventurous of the bunch, feeling unlike typical online slots and stripping away familiar trimmings. Pug Thugs of Nitropolis isn’t quite that left-field, but it does run a payout setup that sits somewhere between clusters and paylines. Put simply, it uses connecting paylines that can begin from all four sides of the grid. The layout features 6 reels, arranged as 4-5-5-5-4 active symbols. Although it’s technically a 6×6 grid, each corner contains special Feature Screens that can trigger random features. Theme-wise, Pug Thugs of Nitropolis takes place on the Pugs’ floating workshop/home/blimp, suspended above a cloudy skyline of skyscrapers. The vibe loosely echoes Guardians of the Galaxy, with a pug stepping into the Rocket Racoon-style role of furry tinkerer and gadget fanatic.

Here, players can set stakes from 20 c to $/€100, with five optional X-iter bonus modes available to switch on. As a highly volatile title, Pug Thugs of Nitropolis runs ELK Studios’ usual 94% RTP regardless of which mode is selected. Wins form from the outer edges of the grid and require at least 3 matching symbols connected in straight lines or diagonally. After a win, all winning symbols and Nitro Reels respin.

The pay symbols on the grid include low card ranks from Jack to Ace, followed by a gun, a computer, a rocket pack, and a pug. A line of 6 matching royals returns 0.5 to 0.7 times the bet, while 1 to 2 times the bet is awarded for a line of 6 matching high symbols. Wilds replace any paying symbol. A full line of wilds pays the same as the top-paying symbol.

Pug Thugs of Nitropolis: Slot Features

Buckle up for the add-ons, where we run through Nitro Reels, Feature Screen modifiers, Nitro Insane, the free spins bonus rounds, and X-iter feature buys.

Nitro Reels

A Nitro Reel is a special symbol that holds a stack of symbols in a single position. The stack size is shown by the number displayed on the Nitro Reel. Nitro Reels can only appear within the central 4×4 area of the grid. Intersecting paylines create a Nitro Reel at the intersection position after the payout. If a Nitro Reel is already present in that spot, it is upgraded to a maximum of 8. Nitro Reels that contain scatter symbols count as just 1 symbol instance. Nitro Reels containing coin symbols add the number of coins shown by the size indicator when collected. After respins, all Nitro Reels land the same symbol.

Feature Screens

The 4 Feature Screens may randomly trigger their own modifier. Multiple modifiers can activate simultaneously:

• Make Big – enlarges a random symbol on the grid into 2×2, 3×3, or 4×4.
• Collect – triggered before win evaluation, it gathers coin values on the grid. Coin symbols respin after a collect, landing either another coin symbol or a pay symbol. This continues until no coin symbols remain visible. The total collected coin value is then paid out. When Collect begins, a Coin Rain may randomly trigger, dropping extra coins onto the reels.
• Nitro Wild – changes one or more Nitro Reels on the grid into Nitro Wilds filled with wild symbols.
• Nitro Match – picks a random symbol on the grid and converts all visible Nitro Reels to match the chosen symbol.

Nitro Insane

The Nitro Insane feature may trigger randomly at the start of any spin. Nitro Insane adds a random number of Nitro Reels to the reels before the spin comes to rest.

Free Spins

Landing at least 3 scatters activates the free spins bonus game – more scatters award more free spins. A Nitro Insane is triggered at the start of each free spin, and the bonus game does not include a super scatter symbol. However, if at least one of the triggering scatters is a super version, the super bonus game is launched instead. In that mode, all Nitro Reels are sticky and stay in place until the feature ends. Hitting 3 or more scatters during bonus play grants additional free spins. The bonus begins only after any potential respins and activated features have finished. Any features that haven’t activated are removed.

X-iter

Using the X-iter, the following bonuses can be enabled:

• Bonus Hunt – 3x the bet for triple the chance of triggering the bonus game.
• Nitro Insane – 10x the bet for a spin with Nitro Insane.
• Nitro Insane Plus – 25x the bet for a spin with Nitro Insane and one random Feature Screen.
• Bonus game – 100x the bet.
• Super Bonus Game – 500x the bet.

Pug Thugs of Nitropolis: Slot Verdict

Even though Pug Thugs of Nitropolis is fairly traditional for a Nitropolis slot in certain respects—especially next to the Rats release—it still manages to bring extra layers to the lineup. Nitro Reels, one of the series’ core building blocks, return again and deliver plenty of the standout sequences. With a cap of 8, they may not reach the same extremes as some earlier Nitropolis games, but combined with the connected-ways payout style and the fact that wins can pay in 4 directions, there’s real potential for lively outcomes.

Then again, maybe not—you never quite know. This is an ELK Studios slot, and they’re not exactly built to be forgiving. They are fun, though, and Pug Thugs of Nitropolis can unleash chaos as well as any of its siblings. The audiovisual package is strong as ever, even if the gameplay can feel unpredictable. It’s also worth remembering this isn’t a cluster pays slot, so you don’t end up wondering why all those Nitro Reels aren’t paying on the respin. They can pay, but only when enough matching symbols connect them to one of the grid’s four sides. It’s a clever spin on the usual cluster/paylines approach and creates plenty of teasing moments with the promise of a payoff. At its peak, Pug Thugs of Nitropolis can reach 25,000x the bet, so it more than holds up on the win potential front.

With Pug Thugs of Nitropolis now ticked off, the four clan-focused Nitropolis slots are complete, leaving the runway clear for Nitropolis 5 to arrive. No pressure on ELK Studios, of course, but it’s difficult not to picture the developer dropping something huge on the gambling community to round off the whole project.
