Nitropolis TV

Developed by the designer ELK Studios, the Nitropolis TV video slot takes us to the top of a building with skyscrapers and towers in the background. In this urban setting, the atmosphere is rather calm in a blue sky with a few clouds. Regarding the game panel, the structure stands in the middle of the screen displaying different symbols. As for the Nitro Reels, they are revealed above the main matrix preserving the connection between the previous titles.

Playable on all media, the Nitropolis TV video slot is aimed at all players thanks to variable bets. The amount starts from $0.10 and reaches $100 per spin. This is a highly volatile slot machine allowing you to pocket a maximum jackpot of 10,000×. The session is carried out on a 6×4 format configuration and contains 4,096 ways to win rewards. When the Nitro Reels are activated, the size of the grid can expand. On the RTP side, the game provides a default redistribution rate of 94%.

To trigger a win, you must collect 6 identical symbols leading to a payment of 0.25 times the stake and 0.5 to 2 times the stake. On the paytable, the symbols present include lower value elements represented by the royal cards. The list also includes higher paying symbols depicted by the characters Rogue Rat, Pug Thug, Gritty Kitty and Dirty Dawg. In addition to the regular symbols, the Wild is active and substitutes for other symbols, except for the Vulture, Scatter or Super Scatter. During the spins, landing a payline of Wilds grants the same value as the highest paying symbol in the game.

Nitro Reels

One of the key elements of Nitropolis TV is the Nitro Reel, a special reel that occupies two positions on the grid and can contain from 2 to 12 identical 1×1 symbols, or Wild symbols. These reels are located in the special row above the main grid and can be activated randomly on each spin.

Once activated, a Nitro Reel remains active for the entire game round and can spin again in two situations: if it is part of a winning combination or at the start of a free spin. When a Nitro Reel reaches the maximum size of 12 symbols, it is instead completely filled with Wild symbols, thus increasing the chances of winning.

Booster Stars

Another interesting mechanic is the collection of stars on the pay symbols, which occurs for each reel and allows you to boost the Nitro Reels above them.

Wild Symbol

The Wild symbol is a wild symbol that can replace any other symbol, except the Vulture symbol, the bonus and the super bonus. If a payline is made up of only Wilds, it is paid with the maximum available value. In addition, all symbols – including Wilds – can appear in three different sizes:

• Standard 1×1;
• Super 2×2;
• Mega 3×3.

The Super Bonus mode is particularly generous: each free spin starts with a Nitro Reel completely full of Wild symbols.

Large Symbols

During the game, symbols of larger sizes than the standard ones can appear. The Super symbols, which occupy an area of ​​2×2, and the Mega symbols, which extend up to 3×3, can appear on any spin, covering multiple positions on the reels. These giant symbols increase the chances of obtaining winning combinations, as they are treated as a group of multiple smaller symbols.

Vulture Feature and Special Features

The Vulture symbol is one of the most unpredictable elements of the game. It can appear on any spin and activate one of the following four features before turning into a Wild symbol:

• Match Up Feature: Selects a random number of low-value symbols and turns them into a high-value symbol or Wild symbols, increasing the chances of obtaining winning combinations.
• Nitro Shift Feature: Swaps the position of some Nitro Reels to create new combinations or extend existing wins. Swaps can also involve inactive Nitro Reels.
• Nitro Upgrade Feature: Activates a random number of Nitro Reels or increases their size, adding more symbols. If a Nitro Reel has already reached the maximum of 12 symbols, it is instead filled with Wilds.
• Both Ways Feature: Allows you to obtain wins not only from left to right, but also from right to left. This feature remains active until the end of the game round or until a bonus is activated.

If the Both Ways feature is activated during the bonus game, it remains active only for the current free spin, while in the super bonus it lasts for the entire special mode.

Bonus Mode

The game offers two free spin modes that are activated when at least three bonus symbols appear in a single spin. Depending on the number of symbols obtained, you receive:

• 3 bonus symbols → 8 free spins;
• 4 bonus symbols → 10 free spins;
• 5 bonus symbols → 12 free spins;
• 6 bonus symbols → 14 free spins.

Super Bonus Mode

If a Super Bonus appears among the symbols, you access the Super Bonus mode, an even richer version in which each free spin starts with a Nitro Reel full of Wild symbols and the Both Ways feature is active for the entire bonus round.

During the free spins, all activated Nitro Reels remain locked and remain active for the rest of the bonus mode. The special game ends when there are no more free spins available or when the maximum win limit is reached.

Purchase X-iter Features

For those who want to jump straight into the action, Nitropolis TV offers the X-iter feature, which allows you to purchase several special game modes:

• Bonus Hunt: Increases the odds of activating a Bonus or Super Bonus game by more than four times. Costs 3x the stake.
• Bullseye: A special spin that guarantees the activation of a Vulture symbol. Costs 10x the selected stake.
• It’s All About the Show: A single spin where an activated Nitro Reel is filled with Wild symbols, the Both Ways feature is active and a Vulture symbol is guaranteed. Costs 25x the selected stake.
• Bonus: Direct access to the Bonus mode at a cost of 100x the selected stake.
• Super Bonus: Direct access to the Super Bonus mode at a cost of 500x the selected stake.

Each free spin begins with a Nitro Reel full of Wild symbols and the Both Ways feature active.

In short, the Nitropolis TV online slot machine designed by the provider ELK Studios favors a slightly more relaxed atmosphere compared to other versions. With the help of the Nitro Reels, bonus rounds and modifiers, the game’s winning cap rises to 10,000×.
