Pug Thugs of Nitropolis Special Features

Pug Thugs of Nitropolis is home to Nitro Reels, Feature Screens, and Nitro Insane features, as well as ELK Studios’ very own X-iter (Bonus Buy) option.

Nitro Reels

Nitro Reels are special positions that cover one symbol containing a stack of symbols. The size indicator on the Nitro Reel indicates the number of symbols within the stack.

Nitro Reels can only appear in the 4×4 central grid area during gameplay. Intersecting pay lines also create Nitro Reels after the win is paid out. If a Nitro Reel is already present, it will upgrade to a maximum of 8 symbols.

Nitro Reels that contain Bonus or Super Bonus Scatters will have their indicators temporarily deactivated, representing only 1 Bonus or Super Scatter. Nitro Reels containing Coin symbols contribute to the number of coins presented by the size indicator when collected. During Respins, all Nitro Reels will reveal the same symbol.

Feature Screens

Attached to the main reel set are 4 Feature Screens (one in each corner), each holding a special Modifier that can trigger at random.

  • Make Big – Expands a random symbol in view until it covers a 2×2, 3×3, or 4×4 symbol position.
  • Collect – Activates before a win evaluation, it collects the values of all Coin symbols currently in view and accumulates their value on screen. Coin symbols will Respin after a collect, landing on either a Coin or regular payout symbol. This is repeated until there are no more Coin symbols in view. At the start of the Collect modifier, a Coin Rain feature may randomly trigger, scattering additional Coins on the grid.
  • Nitro Wild – Converts 1 or more Nitro Reels in view into Nitro Reels containing Wild symbols.
  • Nitro Match – Selects a random symbol in view and matches all present Nitro Reels into the selected symbol.

Nitro Insane

The Nitro Insane feature may randomly trigger at the start of any base game spin. When it does, it places so many Nitro Reels inside the 4×4 central grid area before all other reels stop.


  • Bonus Hunt – Triple the chance of triggering a Bonus Game (3x your bet)
  • Nitro Insane – Triggers a Nitro Insane spin (10x your bet)
  • Nitro Insane Plus – Triggers a Nitro Insane spin and a random Feature Screen (25x your bet)
  • Bonus – 100x your bet
  • Super Bonus – Free Spins with sticky Nitro Reels (500x your bet)

Similar Slots to Pug Thugs of Nitropolis


Pugs are known for their problems breathing – their flat little faces and narrow nasal cavities make it hard for them to do so, yet Pug Thugs of Nitropolis has no issue breathing some life into a beloved series.

After Rogue Rats, we weren’t sure what to expect from subsequent releases. Dirty Dawgs came soon after and kept things more uniform, and Pug Thugs did the same. It’s good news if you’re not a player who wants their slots to resemble anything but a slot, and better news if you’re a big fan of the principal features that makes the Nitropolis series so great.

Pug Thugs of Nitropolis feels like a release that can kick off at any moment, yet it isn’t without an air of predictability that we think ELK Studios games suffer with. When the momentum is in full swing, Pug Thugs of Nitropolis feels like yet another solid release, and the statistics back it up. With a win cap of 25,000x the bet, Pug Thugs of Nitropolis stands proud as a slot with more punch than anyone would think possible of a pug.

The last yet to come is Nitropolis 5, which we’re hoping is the biggest and best yet.
