Bonus Features
Rewind Feature
During the base game and Free Games, a random rewind may occur if a Submarine symbol does not land in the Sub Zone, giving it another chance to appear there. When a Submarine lands in the Sub Zone, a further rewind can randomly trigger, changing selected symbol positions into Special Prize symbols to create additional prize opportunities.
Bonus Game
Free Games are triggered when a Submarine sends ripples into the pots above the reels and begin with 10 Free Games. During the feature, each Submarine that lands can add ripples to the Zones and/or Multiplier collection areas while also collecting all Cash Prize Coin and Special Prize symbols in view and applying its current multiplier to their value. Collecting ripples in the Zones collection area unlocks additional Sub Zones, while collecting ripples in the Multiplier collection area increases the Submarine Multiplier. Each upgrade awards 5 extra Free Games, up to a maximum of 50 Free Games. If multiple Submarines land across active Sub Zones, each contributes ripples and, once a multiplier has been unlocked, each Submarine collects and multiplies all available prizes.
