Bonus Features

Neptune Rising is rich in bonus features that enhance the gameplay and potential winnings. Here’s a look at the exciting features:

  • High-value Symbols: Treasure chests, dolphins, sea horses, and mermaids, providing higher payouts.
  • Top Symbol: Neptune himself is the top symbol, awarding up to 75 times your stake for five across a full payline.
  • Wilds: Neptune’s trident, substituting for all other symbols except scatters, offering up to 900x your stake for five on a payline.
  • Scatters: Ancient Roman gold coins, triggering the Free Spins bonus round.
