How to Play

There are no overly complicated features or mechanics in the Neptune Treasure, so anyone can learn how to play this game right away. It has a 5x3 layout, 10 paylines and several easy-to-understand features, without any jackpot, sadly.

So to start playing this sea-themed slot, you just need to follow a couple of steps:

  • After you have launched the Neptune Treasure slot, the first thing to do is to set your preferred bet: the minimum is €0.10 and the maximum is €30
  • Afterwards, you need to familiarize yourself with Neptune Treasure's rules and the paytable, and for that, click the info button "i" and navigate that menu with arrow buttons that are located next to the cancel and bet buttons
  • Neptune Treasure has a Gamble feature that allows you to gamble your wings but if you don't want this feature you can turn it off in the settings menu; just press the cog wheel button
  • We would also like to note that there is a bonus buy in the game, titled "Power Play" and if you activate you will be able to purchase the Bonus feature. To access this option, click the "Power" icon next to the spin button. In that same menu, there is also a Fast-Play feature: you can buy it and play several game rounds automatically and will instantly get the resulting win. Both of these features will start the game after the purchase
  • Otherwise, when you're ready to play, hit the spin button in the middle and best of luck!

Neptune Treasure RTP and Volatility

9 
The volatility of the Neptune Treasure is medium-high and the RTP is variable.
The 4/5 or high volatility of the Neptune Treasure slot means that while the risk of the game will be increased and you may have a harder time getting a combination of the winning symbols, the payout will be a lot bigger, so a lot of high-stakes players prefer this volatility level. Other than that, Neptune Treasure has a variable Return to Player rate that ranges between 93% to 97%, depending on the casino.

Theme

6.8 

It is clear even from the name that Neptune Treasure is a sea-themed slot since the game takes place in an underwater kingdom of the sea god - Neptune. Now aquatic-themed slots are always very pretty, and this one is no exception as well.

While this game has no background music, with only occasional sounds you hear when spinning reels and generally interacting with the slot, the design of Neptune Treasure is pretty: the scenery of the sea kingdom is vibrant and well done, and the gold reels with pearls and bubbles fit the overall aesthetics really well.

The symbols of the Neptune Treasure are also pretty and follow the slot's theme. Here you will see such symbols as 9-A (which are the lowest paying symbols) symbols of the dolphin and the longship, which are worth the same amount, the building and the mermaid, the latter is also the highest paying symbol in the game.

Plus, the Neptune Treasure has 2 special symbols: Scatter and Wild. Not only do both of them have a value, but they also have special properties: Wild is the Neptune and it will substitute for all symbols except Scatter, plus it will double the win when substituting. Scatter is a treasure chest, and it will help you trigger the Bonus Feature.

With its nice design, decent features and a good top win, we think a lot of players will like the Neptune Treasure slot. The buy bonus makes it a lot more convenient for the players, and the multipliers on both the Wild symbol and during the Bonus Feature give a lot of winning possibilities! So we think Neptune Treasure is certainly worth giving a try, especially if you like a bit simpler slots but with good prizes and pretty themes.
