Getting Started with Nitropolis 4

Nitropolis 4 is an online slot game developed by ELK Studios. The game is played on 6 reels and starts with 4 rows, with the possibility for reels to expand up to 8 rows. You can place bets from a minimum of £0.20 up to a maximum of £4 per spin. Each spin uses 100 coins, and the payout is based on the symbol combinations according to the paytable.

How to Play

  • Begin each game round by selecting your bet amount within the allowed range and pressing the Spin button.
  • Winning combinations must start from the leftmost reel and pay left to right on consecutive reels. If the Both Ways feature is active, wins can also start from the rightmost reel and pay right to left.
  • Only the highest win per active payline is awarded.
  • All payouts for wins and combinations follow the paytable.

Understanding Winnings

  • All winnings are displayed in your chosen currency or in coins. These preferences can be adjusted in the settings.
  • The game has two modes: a normal mode and a bonus mode with free spins.

Ways to Win and Special Symbols

  • Every spin in normal mode begins with 4 rows, totalling 4,096 possible ways to win.
  • Nitro Reels are special features that can cover two symbol positions, while big Nitro Reels can cover six symbol positions. Regardless of size, a Nitro Reel counts as a single 1x1 symbol.
  • Nitro Reels may contain a super bonus symbol, impacting bonus mode triggers.

Key Symbols

  • The wild symbol can substitute for any symbol except for bonus and super bonus symbols. If a payline consists entirely of wilds, it pays out as the highest value symbol.
  • The Nitro Multiplier acts as a blocker and multiplies all wins in view by a value between x4 and x12.

The Avalanche Feature

Nitropolis 4 uses an Avalanche feature, where winning symbols (except Nitro Reels) explode after a win. The remaining symbols fall to the bottom, and new symbols appear to fill the spaces. The Avalanche process continues as long as new winning combinations occur during a spin.

Nitro Booster Features

  • The Nitro Booster contains eight different features. Five of these affect the main reels, while three affect Nitro Reels.
  • The Redrop feature is activated when there are no more wins, causing Nitro Reels to respin.
  • The Both Ways and Max Rows features are disabled if the bonus mode is triggered.

Bonus Mode and Free Spins

  • Landing three or more bonus symbols in a single spin triggers the bonus mode, awarding free spins.
  • Additional spins can be won during bonus mode, and all winnings are awarded at the end of this bonus session.
  • The bet level cannot be changed during an active game round.

RTP and Malfunction Policy

  • The Return to Player (RTP) value is displayed within the game interface.
  • If a malfunction occurs, all bets and wins from the affected round are voided.
