Nitropolis TV Slot Review

Game Rules

Nitropolis TV is a 6-column, 4-row slot with spinning reels and an extra row above the field with Nitro Reels.

Wins start from the leftmost reel and are paid from left to right on adjacent reels only. If the Both Ways feature is activated, wins can start from the rightmost reel and are paid from right to left on adjacent reels only. Gaps between reels do not count. Only the longest line on each active payline is paid.

Nitropolis TV has two modes – a regular mode and a bonus mode with Free Spins. All Spins in the regular mode start with 4 rows and 4,096 winning combinations.

An active Nitro Reel takes up two symbol positions and contains 2, 4, 6, 8, 10 or 12 identical 1×1 payout symbols or Wild symbols. All Nitro Reels are placed in a special row above the field. Each initial Spin can activate one or more Nitro Reels of a random size.

Activated Nitro Reels remain in play until the end of the round.

When Nitro Reels are activated, a Spin occurs. An activated Nitro Reel performs a Respin if it enters into a win and at the beginning of each Free Spin.

Stars on the payout symbols are collected sequentially from each reel and are used to activate and/or increase the size of the Nitro Reel above each reel to accommodate more symbols. Collection occurs before the Respin. If the Nitro Reel has reached the maximum size (12), it will fill with Wild symbols.

Upgrading Stars

Stars appear randomly on winning symbols and are collected reel by reel to activate and/or enlarge the Nitro reels.

Vulture Features

Spinning the vulture symbol triggers the random vulture feature and then the symbol turns wild.

Nitro Upgrade

A random number of Nitro Reels are triggered and/or upgraded to contain more symbols.

The Nitro Upgrade feature activates a random number of inactive Nitro Reels and/or increases the size of already activated Nitro Reels to accommodate more symbols. If the Nitro Reel selected for upgrade has reached the maximum size (12), it will be filled with Wild symbols instead.

A combination of 3 or more bonus symbols during normal mode triggers the bonus mode with Free Spin.

• 3 bonus symbols: 8 Free Spins
• 4 bonus symbols: 10 Free Spins
• 5 bonus symbols: 12 Free Spins
• 6 bonus symbols: 14 Free Spins

Nitro Shift

A random number of Nitro Reels will swap places.

The Nitro Shift feature swaps a random number of Nitro Reels in an attempt to create a new win or extend an existing one. An inactive Nitro Reel may be swapped. Swapping occurs before a win is assessed.

Match Up

A random number of low-value symbol types are substituted with one high-value symbol type or Wild symbol.

The Match Up feature selects a random number of low value symbol types on the field and replaces them with the same high value symbol or Wild symbol. The replacement occurs before the win is assessed.

Both Ways

Evaluates wins from both full left and full right reels.

The Both Ways feature activates the win evaluation on both sides. All win lines are paid first from left to right, starting with the leftmost reel, and then from right to left, starting with the rightmost reel. After that, the Both Ways feature remains until the bonus mode is activated, or until the end of the game round. The Both Ways feature remains active until the end of the current Free Spin, if activated in the bonus mode. It also remains active throughout the Super Bonus game.

The active Both Ways feature is deactivated in the bonus mode.

Nitro Reels

The Nitro reel covers one of the top six positions above the symbol grid.

A combination of bonus symbols and a super bonus symbol activates the super bonus game, where each Free Spin starts with a Nitro Reel of Wild symbols and the Both Ways feature is active throughout the bonus round.

During Free Spins, all activated Nitro Reels are saved and remain in the game until the end of Free Spins.

The Free Spins bonus game ends when the Free Spins end or when you reach the winning limit. Wins are paid at the end of the bonus mode. You cannot change the bet after the round has started.

Wild Symbol

The wild symbol substitutes for all symbols except the vulture, bonus and super bonus symbols.

The Wild symbol substitutes for any symbol except the Vulture, Bonus, and Super Bonus symbols. A payline of Wild symbols pays out on the highest value symbols.

The Wild symbol and the low and high value symbols come in three sizes: Standard (1 x 1), Super (2 x 2), and Mega (3 x 3). All the big symbols are made up of several 1 x 1 symbols that they cover. For example, the Super (2 x 2) contains 4 standard (1 x 1) symbols.

The Vulture symbol can appear in any Spin. It activates one of four features: Match Up, Nitro Shift, Nitro Upgrade or Both Ways, then turns into a Wild symbol. The Vulture symbol is activated before the win is assessed.

Big Symbols

Super 2×2 and Mega 3×3 symbols can appear on every spin or symbol drop.

Bonus Game

Bonus Symbol

Three or more bonus symbols trigger the free spins feature. All Nitro reels are fixed during free spins. A bonus symbol that spins during the bonus game awards +1 free spin.
