The nitro gang is back and this time they’re in paradise, well as much of a paradise as a post-apocalyptic beach can be, really. Avoid the toxic waste and the nuclear debris while sipping on your cocktail and relaxing under the tropical umbrella.

Play with single stacking symbols, mystery boxes, large icons, and many more bonus features that’ll have you wanting to dip your toes in the slightly irradiated waters of the beachfront. Land Scatters to activate bonus spins all while jamming out to a funky beat.

Read on as we outline all the different extras that you can expect to come across while playing this game. Be on the lookout for different symbols and interesting grid interactions as well.

Warm, Irradiated Sands

The title opens up with a brief cinematic that’ll give you a pretty good idea as to what you’re getting into. The gang is indeed back and ready to stir up some chaos as always. If you’re unfamiliar with the gang, they’re a group of rough and tough animals that have been slightly altered by all the radiation.

When you first get to look around the game you’ll notice the cocktail sitting on the little table by the umbrella on the beach sand and you might think that this would be a lovely place to visit. Then you start to notice everything else like barrels of toxic waste that have glowing green goop oozing out of them, some destroyed buildings in the background and the unnatural blue haze that blankets the area.

The soundtrack is amazing. It’s a really funky and upbeat tune that has some of the gang’s barks and squeaks remixed in. While it is a great tune, the option to mute the game audio is available at any point. The sound effects are great, they keep you informed and on your toes, especially during the anticipation reel spins.

The game stays true to what made the original entries so fun and unique. The whacky setting and interesting cast of characters make the game a joy to play. ELK Studios has done a great job adding this release to its catalogue.

If you come across the game while browsing your favourite online establishment, don’t panic. The world hasn’t gone up in nuclear fire, but try the game out anyway, to find out how to make the best of it if it does.


It’s time to make sure that everyone is here. We’ll cover all of the symbols that you’ll most likely come across while playing the game. Keep in mind that symbols have the chance to land as either 1×1, 2×2, 3×3, or 4×4.

Starting off, we have low-paying icons. These are all represented by royals on playing cards. Expect to see J, Q, K, and A appearing quite often on the grid. All of these icons are worth the same.

Next in line are the medium-paying images. Represented by patches for the various animals, you should be on the lookout for the Rouge Rats, Pug Thugs, Gritty Kitty, and Dirty Dawgs icons. Of these images, the Gritty Kitty and Dirty Dawgs symbols are worth the most.

Finally, we come to the high-paying symbols. These are all represented by the different animals. You’ll be wanting the rat, pug, cat, and doberman. Out of all of these, the doberman is the most valuable icon.

A toxic martini is the WIld for this game. The Wild will substitute for any other common icon in the game, allowing you to build winning combos with ease or extend your already existing ones for bigger wins.

A blimp represents the Scatter for this title. Landing at least three of these will activate the bonus gameplay feature.

There are more special symbols that are active during special features so we’ll go over them in the features section of the review.

Nuclear Power!

Nitropolis 3 is a cascading video slot game that is played on a grid that starts off with 6-reels and a varying number of rows but as the game progresses, more rows can be added to the grid. The theoretical return to player rate is around 95% with a volatility high rating. Bets can range from between 0.20 – 50 coins per spin with the highest obtainable win being 50,000x the bet.

Join The Gang

On winning spins, symbols that are involved in the win will disappear leaving room for new icons to fall in and take their place. When this occurs a new row is added to the grid up to a maximum of 8. This process will continue as long as new wins form.

Nitro Reels have a chance of forming on the grid. Nitro Reels either cover a minimum of two symbol positions and house 4, 6, 8, 10, or 12 1×1 paying symbols or up to 6 symbol positions and contain 2, 3, 4, 5, or 6 2×2 paying symbols.

Nitro Features include the following abilities:

  • Nitro Match: Should a Nitro Reel land on the same or adjacent reel to this icon, it will match the symbols.
  • Nitro Upgrade: If this symbol and a Nitro Reel are on the same or an adjacent reel, symbols will be upgraded and additional icons will be added to the Niro Reel.
  • Nitro Wild: Symbols in the Nitro Reel, as well as this symbol, will become Wild so long as the Nitro Reel and this icon are in the same or adjacent reel.

    There are additional bonus symbols that can land on the reels. These include:

    • Redrop: All bonus symbols and Nitro feature symbols remain on the grid, Nitro Reels re-spin during this feature.
    • Both Ways: All winnings will be paid out from left to right and from right to left.

      By landing either 3, 4, 5, or 6 Scatters on a single symbol drop, you will be awarded 8, 12, 16, or 20 bonus spins respectively. During this feature, all Nitro Reels are sticky and bonus spins can be re-triggered. On each new spin of the bonus feature, the safety level will increase by one, adding an additional row.

      If you’re lucky enough you can trigger bonus spins by landing a combination of Scatters and Super Bonus Game symbols. Should this happen, the bonus spins will start at the maxed out 8 rows and have Both Ways active.

      Embrace The Insanity!

      While it’s a little disappointing that the RTP for this title is only around 95%, it is still a lot of fun. If you’re hesitant to commit real money to the game, play it for fun.
