Game Features and Special Symbols

  • Wild Symbol: Substitutes for any symbol except the bonus and super bonus symbols. A payline of only wilds pays as the top-value symbol.
  • Nitro Multiplier: Acts as a blocker and multiplies all visible wins by values ranging from x4 to x12.
  • Nitro Reel: Covers two symbol positions, while a big Nitro Reel spans six symbol positions. Despite their size, both types count as a single 1x1 symbol. Nitro Reels can contain a super bonus symbol.
  • Nitro Booster: Offers eight distinct features: five impact the main reels, and three influence the Nitro Reels. The Redrop feature is triggered when no further wins occur, causing the Nitro Reels to respin. Both Ways and Max Rows features are deactivated if Bonus mode is activated.

Avalanche Feature

During spins, all wins in the current round are accumulated. Winning symbols explode (except for Nitro Reels), and the remaining symbols drop to fill open spaces. New symbols then fall from above to refill the grid. The Avalanche continues for as long as new winning combinations form.
