Nitropolis TV has two game modes: normal mode and bonus mode with free spins.
All normal mode drops start with 4 rows and 4096 ways to win.
An active Nitro Reel spans two symbol positions and contains 2, 4, 6, 8, 10 or 12 identical 1x1 paying symbols, or Wild symbols. All Nitro Reels are located in a special row on the symbol board. Each initial spin can trigger one or more Nitro Reels of random sizes.
Active Nitro Reels remain in play until the end of the game round.
A Nitro Reel spins when activated. An active Nitro Reel respins when it is part of a win and at the start of all free spins.
Stars are collected from the paying symbols reel by reel and used to trigger and/or increase the size of the Nitro Reel above each reel to hold more symbols. The collection takes place before a respin. If a Nitro Reel has already reached the maximum size of 12, that Nitro Reel will be filled with Wild symbols instead.
The Wild symbol substitutes for any symbol except the Vulture, Bonus and Super Bonus symbols. A Wild-only payline pays as the highest value symbol.
The Wild symbol and all low and high value symbols come in three sizes: Standard 1x1, Super 2x2 and Mega 3x3. All large symbols count as the number of 1x1 symbol units they cover. For example: a 2x2 Super counts as 4 Standard 1x1 symbols.
The Vulture symbol can appear on any spin. It triggers one of four features: Match Up, Nitro Shift, Nitro Upgrade or Both Ways, and then turns into a Wild symbol. The Vulture symbol is activated before the win evaluation.
The Both Ways feature activates the evaluation of wins from both sides. Connections in both directions are then paid from left to right starting from the leftmost reel, and
from right to left starting from the rightmost reel. The Both Ways feature then remains active until the bonus mode is triggered or until the end of the game round. If triggered in the bonus game, the Both Ways feature only remains active until the end of the current free spin, but remains active throughout the super bonus game.
If active, the Both Ways feature is deactivated when bonus mode is activated.
The Match Up feature chooses a random number of low value symbol types currently in view and replaces the number of symbol units with the same high value symbol, or Wild symbols. The substitution takes place before the win evaluation.
The Nitro Shift feature swaps the positions of a random number of Nitro Reels in an attempt to generate a win or extend an existing one.
A shift could include an inactive Nitro Reel. The shift takes place before the profit evaluation.
The Nitro Upgrade feature activates a random number of inactive Nitro Reels and/or increases the size of active Nitro Reels to hold more symbols. If the Nitro Reel selected to be upgraded has already reached the maximum size of 12, that Nitro Reel will be filled with Wild symbols instead.
A combination of three or more bonus symbols during normal mode activates the bonus mode with free spins.
- Bonus symbols: 8 free spins
- Bonus symbols: 10 free spins
- Bonus symbols: 12 free spins
- Bonus symbols: 14 free spins
A combination of Bonus symbols with a Super Bonus symbol triggers the Super Bonus Game, where all Free Spins start with a Nitro Reel filled with Wild symbols, and the Both Ways feature remains active throughout the bonus round.
During free spins, all active Nitro Reels are reserved and kept in play for the remainder of the free spins.
The bonus game with free spins ends when there are no free spins left or when the win limit has been reached.
Winnings will be paid at the end of the bonus mode.
Bets cannot be changed during an ongoing game round.
A game round will end immediately when the winning limit is reached; then the winnings accumulated up to that point will be paid out.
The theoretical payout (RTP) on Nitropolis TV is 94.0%.
The maximum total win in a game round is limited to 10,000 times the bet placed.
If a malfunction occurs, all bets and prizes are void.
