Technical Overview

Nitropolis is an online slot game developed by ELK Studios. The game has 6 reels and 4 rows, beginning each round with 4,096 possible ways to win, which can expand up to 85,155,840 ways through in-game features. The minimum bet per spin is £0.20 and the maximum is £4.00.

Win Mechanics

  • Winning combinations are formed starting from the leftmost reel and must land on consecutive reels without any gaps.
  • Only the longest winning combination per active payline is paid.
  • Payouts are made according to the paytable and can be displayed either in the player’s currency or in coins. This setting can be changed in the game’s options.

Game Flow

  • A round begins with the player selecting a bet and pressing the Spin button.
  • All bets are placed at the chosen bet level; no changes to the bet can be made during an active spin or within Bonus mode.
  • Results and winnings for each round are calculated based on the symbols and features activated in that spin.

Symbols and Features

  • The wild symbol can substitute for any standard symbol except the bonus symbol. If a payline consists entirely of wilds, it pays out as the highest value symbol on the paytable. During free spins, wilds also substitute for the scatter paying symbol in a scatter win.
  • Nitro Reels are special reel features that cover two symbol spaces and can contain 4, 6, 8, 10, or 12 identical symbols. For example, a Nitro Reel of size 8 contains 8 standard 1x1 symbols.

Nitro Reels Dynamics

  • A bonus symbol inside a Nitro Reel only counts as one, regardless of the reel’s overall size. When a bonus symbol exits a Nitro Reel, the Nitro Reel retains its current size, increasing the number of possible win ways again.
  • Whenever a winning combination occurs, all the symbols and Nitro Reels included in that win respin individually, and this process repeats as long as new wins are formed.
  • The starting number of ways to win is 4,096 and can expand further with additional Nitro Reels and greater sizes, up to 85,155,840 possible ways.
  • A Nitro Reel may land on an initial spin or be triggered when two vertically adjacent symbols respin after a win.
  • During respins or between free spins, one or more Nitro Reels in view may increase in size at random.
  • Nitro Reels may also respin independently at the end of a spin if no further wins are achieved.

Bonus Mode and Free Spins

  • Landing three or more bonus symbols during the base game activates the 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
  • Three or more bonus symbols during Bonus mode retrigger additional free spins, using the same system as the initial trigger.
  • In Bonus mode, a symbol is randomly chosen as a scatter paying symbol. Up to three scatter symbols can be selected this way.
  • Any Nitro Reels present on the reels at the start of Bonus mode are locked in place and remain for the remainder of the free spins.

Scatter Wins in Bonus Mode

  • During Bonus mode, a randomly selected symbol acts as a scatter and three or more such scatter symbols on different reels trigger a win.
  • If the scatter paying symbol also forms a normal winning combination, only the scatter win is awarded.
  • The Bonus game ends when no free spins are left or the win cap is reached. All winnings are awarded at the conclusion of the Bonus game.

Maximum Win and Game Integrity

  • The maximum possible payout is capped at 10,000 times the total bet per spin.
  • When this win cap is reached, the game round ends immediately, and all accumulated winnings are paid out.
  • If a malfunction is detected, all bets and winnings for that round are void.

Additional Information

  • The return to player (RTP) percentage is displayed within the game itself.
