This Roman Mythology-themed slot has all the features eager players want, with its classic 20 paylines and 5 reels mechanic.

8 symbols circulate through Royal League Neptune’s Harem slot’s reels. The first half symbols are lower valued ones such as pearls, seashells, oysters, and stars. While the other 4 higher paying symbols represent the 4 beautiful mermaids of Neptune. They are dressed in colorful dresses like purple, green, blue, and red.  With the maximum bet applied, you can win a total prize of £250,000!

To achieve a maximum win of 10,000x your stake you need to land on 5 Neptune tridents wild symbols. You can also achieve this through a bonus feature but more on that a bit further on this Royal League Neptune’s Harem slot review.


This slot has a standard type of gameplay featuring 5×3 reels. Its soothing soundtracks will make you feel like you’re in the depths of the sea and who knows maybe you will find Nemo there. The principal features consist of the bonus features and we’ll go into detail about them below.


King Neptune and his 4 mermaids are made out of 20 fixed paylines and their direction for a winning combination is from left to right. For you to receive a win, 3 symbols ought to be matched according to their reels and paylines. Besides the ordinary symbols and the trident wild, there are bonus symbols and gemstones with different colors.


This feature activates randomly on any given spin you make. When you finally activate it, the reels turn into a 7×7 grid and will fill up with all kinds of gemstones.

Different colored gems have different payouts and to match one of those you need to throw 2 dice. From the highest payout to the lowest they are as follows:

Gold Gemstone – 10,000x your wager

Red Gemstone – 1000x your wager

Green gemstone – 100x your wager

Blue Gemstone – 10x your wager


To activate this bonus feature you need to land on 2 bonus symbols only on the first and last reel. When you manage to land on them, a screen will appear consisting of 4 cards. From those four cards, you need to choose one so a number of free spins correlating with the card are handed out to you. The number of free spins is 12, 10, 7, or 5.

After all is said and done, there’s still more to come. Another screen will appear, again with 4 cards, only this time you will choose a multiplier instead of free spins.


From a classic game arrangement to amazing in-depth gameplay and a great theme that involves the Roman god of the Sea, Neptune, this slot is tailored for every newbie and high-roller.
