• Glowing pearls, seashells, scallop shells, and stars are the low-paying symbols.
• The four mermaids are the high-paying symbols.

• A trident is the wild that stands in for any other symbol aside from the bonus and scatter.
• The bonus symbol is golden double doors that activate free spins.

Free Spins

If 2 bonus symbols appear on reels 1 and 5, you will have to choose from 4 cards to claim between 5 and 12 free spins and then you will make a second selection to gain a multiplier of between 2x and 10x.

Royal League Jackpot

During the base game, this feature randomly transforms the reels into a grid filled with different coloured gems. You will roll a pair of dice that will move you around the grid until the crown symbol is rolled. Once this happens the feature will end and you will be paid a jackpot prize that corresponds to the colour of the gem you end up on. You can claim jackpots of 10x, 100x, 1000x, or 10 000x your stake for the blue, red, green, or gold gems, respectively.

Neptune’s Harem slot is a sexy undersea adventure with a thrilling feature. The game’s theme is a bit of a humorous jab at the otherwise serious world of Roman mythology and the alluring mermaids add enough eye candy to keep you visually engaged. The free spins feature brings decent potential to the table, thanks to its multipliers, but the slot’s top prize sleeps within the Royal League Jackpot mini-game where you can win up to $250 000. While the theme feels like it could stand for some more development, this is an enjoyable and rewarding slot experience.
