What Is the Format of Nitropolis?

Nitropolis is a 6-reel, 4-row online slot developed by ELK Studios. The game offers up to 85,155,840 ways to win. Bets range from a minimum of £0.20 to a maximum of £4.00 per spin.

How Do the Game Rules Work?

  • Winning combinations start from the leftmost reel and pay only left to right on consecutive reels, without gaps.
  • Only the longest win per active way to win is paid out.
  • Players begin a game round by selecting their bet and pressing the Spin button.
  • All wins and winning combinations are paid based on the paytable.
  • Winnings can be displayed in the player's currency or in coins, with the option to set this preference.

What Are the Game Modes?

Nitropolis can be played in two modes: Normal mode and Bonus mode with free spins if activated.

  • Both modes start each spin with 6 reels, 4 rows, and 4,096 ways to win.
  • The wild symbol can replace any other symbol except the bonus symbol. A winning line consisting entirely of wilds pays the highest value symbol's prize. During free spins, wilds substitute for the scatter-paying symbol in a scatter win.
  • Nitro Reels occupy two symbol positions and can have a size of 4, 6, 8, 10, or 12. The size indicates how many identical 1x1 symbol instances are inside the Nitro Reel (for example, size 8 contains 8 single standard symbols).

What Are Nitro Reels and How Do They Work?

  • If a bonus symbol appears within a Nitro Reel, it counts as one symbol, and when the bonus symbol moves out, the Nitro Reel keeps its size. The number of ways to win increases as more Nitro Reels land or grow in size.
  • After a winning spin, all winning symbols and Nitro Reels respin individually, and this repeats as long as new wins occur.
  • The number of ways to win starts at 4,096 and can increase up to 85,155,840 as more and larger Nitro Reels land.
  • Nitro Reels may appear on the initial spin and can also appear randomly when two vertically-adjacent symbols respin after a win.
  • During respins or between free spins, one or more Nitro Reels may randomly increase in size.
  • Nitro Reels may randomly respin at the end of a spin when there are no more wins.

How Is the Bonus Mode Triggered?

  • Three or more bonus symbols in Normal mode activate Bonus mode with free spins:
    • 3 bonus symbols: 10 free spins
    • 4 bonus symbols: 15 free spins
    • 5 bonus symbols: 20 free spins
    • 6 bonus symbols: 25 free spins
  • An additional three or more bonus symbols during Bonus mode award extra free spins, determined in the same way as the initial trigger.
  • Up to three paying symbols can be selected for scatter wins during the bonus feature.
  • All Nitro Reels lock in place for the duration of the free spins and remain for all remaining spins in the bonus mode.

How Are Winnings Calculated and When Does the Game End?

  • In Bonus mode, a random paying symbol is selected for scatter wins. At least three such symbols must land on three different reels to generate a scatter win.
  • If a symbol is chosen for the scatter win and forms both a scatter and a normal win, only the scatter win is paid out.
  • The free spins bonus ends when all free spins are used or when the win cap is reached. All winnings are paid out at the end of the bonus round.

What Additional Information Do Players Need to Know?

  • Bets cannot be adjusted during an ongoing spin or while Bonus mode is active.
  • If the win cap is reached during play, the game round ends immediately and winnings collected are paid out.
  • Players can view the RTP value within the game itself.
  • The maximum potential win in Nitropolis is capped at 10,000 times the placed bet.
  • All bets and wins are void in the event of a malfunction.
