Plus, you can catch way more symbols on the reels. Keep an eye on the box above the reels since it displays the number of wins. If you catch a reel that contains 24 symbols you’ll play with 191,102, 976 ways to win.

Winning Re-spin

The next important bonus round is the Winning Re-spin feature. You’ll initiate the bonus when the Nitro Reels and all the symbols form a winning combo.

Not only do they offer you a re-spin but the non-winning symbols lock onto the reels. Therefore, it’s possible to catch successive winners on the condition new winning combos occur.

During the free spins, the Nitro Reels remain on the reels. The maximum number of ways to win can increase to 13 million ways on a single free spin! Moreover, when the Nitro Upgrade drops onto the Nitro Booster the symbols increase. This offers you more ways to win during the Nitro Reels.

Now, when the Nitro Booster feature lands it offers you Both Ways wins, high-value symbols, and wilds. You can trigger extra free spins as well when more scatters appear.

Nitropolos 2 Tips & Strategy

We played Nitropolis 2 with a casino budget of $1,000 at an average bet of $4 per spin. This is higher than our usual foray. There was a method to our madness as well because the volatility has the bite force of a Megalodon shark.

The hit frequency is exactly like Elk Studio advertises it on the label. During our testing phase of 70 spins. We triggered the Free Spins feature on our 67th spin for a payout of $200.

Perhaps not as much as we hoped. What’s important is that we made a profit of $110 on a highly volatile slot! And, in our book that counts a lot.

Moreover, the biggest win we had in the main game was $70 (17.5x our stake). On the whole, most certainly not a bad day at the office.


Hats off to Elk Studios with Nitropolis 2. It’s more or less a copycat of the original but the studio juices it up with plenty of extras. By the way, all of them are good! Perhaps the only letdown is the jackpot of 10,000x.

We say this because with more than 191 million ways to win we expected a far bigger jackpot. Players looking for another adrenaline fix can try, Nolimit City’s, San Quentin. It offers a blistering 46,656 ways to win and a Free Spins feature with Jumping Multipliers of up to 512x!
