Game Overview

  • Nitropolis 4 is an online slot from ELK Studios with 6 reels and 4 rows as the standard layout. The reels can expand up to 8 rows during play.
  • Betting limits range from a minimum of £0.20 to a maximum of £4 per spin.
  • Each spin is played at a bet size of 100 coins.

Ways to Win

  • The game offers 4,096 ways to win at the start of every spin in normal mode, with the potential for more as the reels expand.
  • Winning combinations are formed from the leftmost reel to the right on consecutive reels. If Both Ways is active, wins can also form from right to left.
  • Only the highest win per active payline is awarded. All wins correspond to the paytable.

How to Play

  1. Select your preferred bet level between £0.20 and £4.
  2. Start a game round by pressing the Spin button.
  3. Match symbols on consecutive reels starting from the far left (or also from the right if Both Ways is active) to land winning combinations.
  4. View your winnings in your chosen display format: either in coins or your selected currency, which can be changed in Settings.
  5. When a winning combination appears, the Avalanche feature is triggered. Winning symbols disappear (except Nitro Reels), allowing new symbols to drop in, potentially leading to further wins in a single round.

Symbols and Features

  • The wild symbol substitutes for all symbols except the bonus and super bonus symbols. A line of only wilds pays as the highest symbol value.
  • Nitro Reels are special symbols that cover two positions on the reels, or six positions if it is a big Nitro Reel. They can include a super bonus symbol but always count as one 1x1 symbol for calculation purposes, regardless of their size.
  • A Nitro Multiplier may appear as a blocker symbol, increasing win values in view by a multiplier amount ranging from x4 to x12.

Avalanche Feature

  • All wins collected during a spin trigger the Avalanche mechanic. Matching symbols are removed except Nitro Reels, remaining symbols fall, and new symbols fill the empty spots. The process repeats as long as new wins occur.

Nitro Booster Features

  • The Nitro Booster offers eight varying features: five affect the main reels and three apply to the Nitro Reels.
  • The Redrop feature is activated when no other wins appear, causing all Nitro Reels on the grid to respin for another chance at winning combinations.
  • If Bonus mode is entered, Both Ways and Max Rows features are deactivated for the duration of the bonus.

Bonus Mode and Free Spins

  • Landing three or more bonus symbols in a single spin triggers Bonus mode, awarding free spins.
  • During Bonus mode, it is possible to earn additional free spins.
  • All winnings achieved during the bonus are paid out after Bonus mode concludes.
  • Bet sizes cannot be adjusted while a game round is in progress.

Additional Information

  • The Return to Player (RTP) value is displayed within the game interface.
  • Should a malfunction occur, any bets and winnings from that round are voided.
