Nitropolis 4 Slot Gameplay & Overview
Featuring a menacing soundtrack, and graphics to match, Nitropolis stars an array of shady animals, so you'll be looking out for symbols like a hairless cat, a pug with a helmet, and the highest-paying symbol of the terrifying doberman.
A wild symbol can substitute for any symbol except the bonus or super bonus symbol, and a payline of all wild symbols pays out the highest-value symbol.
Several special features like bonus spins, big symbols, and the X-iter allow you to purchase your way into a specific part of the game.

Big Symbols & Mega Symbols
Big symbols cover larger areas of the game grid and can appear on any spin or symbol drop. Super Symbols are 2x2 in size, while Mega Symbols are 3x3.
Nitro Reel & Nitro Match
Nitro Reels cover two symbol positions and contain up to 12 payout symbols, while Big Nitro Reels cover a massive six symbol positions. This increases your number of ways to win, in the same way as a Megaways slot might. The Nitro Wild feature fills the Nitro Reel with wild symbols.
There is also a Nitro Match feature, where an existing Nitro Reel matches the current symbol in view to deliver a payout.
Nitro Multipliers
Nitro multipliers cover two symbol positions and multiply all wins in view by up to 12x.
Nitro Booster
The Nitro Booster adds one of eight different features to the main reels. For example, in the Redrop feature, all standard symbols are removed, and new symbols drop into their place; the Both Ways feature pays winnings from right to left as well as left to right, and the Max Rows feature expands the game grid to the maximum of eight rows.
Bonus Game
If you land three of the bonus symbols (a submarine), you’ll get eight bonus spins, and the number increases to 20 if you land six bonus symbols. All Nitro Reels are sticky during free spins, and free spins can be re-triggered. There’s also a super bonus game, played with the maximum number of rows (eight) and the Both Ways feature activated.
X-iter
X-iter is a unique way of playing slots, now integrated into several ELK Studios games, including Nitropolis 4. If you click on the X-iter option on the game screen, you can choose from five different exciting modes, each of which costs a different amount. This is a way to get straight to the action, for example, by buying the bonus or “Super Play” round.
Bet Sizes, Max Win & Return to Player (RTP)
Nitropolis 4 offers thousands of ways to win, especially when the maximum eight rows are activated. The RTP of the game is 94%, and it has a high-volatility title. You can bet anything from 0.20 to 100, and with a maximum win of 50,000x your stake, you could be looking at a win of up to 500,000.
