Theme, Soundtrack and Symbols

If the name hasn't completely given it away, the latest in the Diamond Tales series by Greentube is a game themed around the epic tale of our beloved sea princess, Ariel. In this video slot, you'll join the mermaid and her friends on an underwater adventure.

The design of the slot is absolutely beautiful, with the soundtrack giving the feel of going underwater, and the book of epic tales open to the left of the reels to start the story of Ariel and her prince. In the backdrop, you see the castle and animations of fish swimming.

On the reels, you will find the low-value symbols indicated by shells with card royals A, J, K, and Q. The higher-value symbols include the trident, Ursula, the crown and sword, the vials of the potion, Ariel, and Prince Eric.

Game Mechanics

Diamond Tales: The Little Mermaid is a 5 reel, 4 rows, and 40 paylines video slot powered by Greentube and Novomatic. The slot awards wins on combinations of three or more and pays out from left to right.

You can play the game on any device from as little as €0.40 to up to €40 per spin. The game also comes with a Turbo and Auto feature which you can use to speed up the gameplay and enjoy the visuals instead of manual gameplay.

This summer slot has adaptable volatility, meaning it can be low to high and the hit rate will change based on that. You can change the volatility of the game after you have unlocked it by reaching the particular volatility Chapter in the game. The maximum payout you can trigger is a whopping 50,000x your stake.

Special Features

Diamond Tales: The Little Mermaid is an exciting slot game with many fun features.

Snap Drop Feature

This feature is triggered when a Snap Drop Scatter lands on reel 5, and you have a pearl of hearts in the special reel at the top. Then you receive one re-spin featuring only the pearl of hearts with multipliers. After the spin, the multipliers are totalled, and this sum boosts your total bet.

Diamond Tales Feature

Three book bonus symbols landing on reels 1, 3, and 5 will trigger the Diamond Tale feature. During the feature, all pearl heart symbols on the special revolution will remain locked in place, increasing their value by 1x.

During this feature, each position on the grid is an individual reel. The feature awards you 3 free spins, and this gets reset back to 3 whenever a Pearl or Gold Diamond heart lands on the reels.

The Special Reel + Chapter Progression

Above the reels is a special reel where you will collect pearl hearts contributing to the Heart Collection counter. This helps you move from one chapter to the next. The game has 150 chapters, and the bar shows how many hearts are needed to progress to the next chapter.

As you climb the chapters, you can unlock different features, including the Cove, Lagoon, Bay, and Sea, with the last being the Ocean feature.

Ocean Feature

This feature can only be triggered during the final chapter of the game. During this feature, you can land up to 5 gold diamond hearts in the Diamond Tales feature. The last chapter will stay unlocked for 7 days before resetting back to Chapter 1.

Play 'On The Go'

One of the best things about fairytales is the happily ever after, and when it's combined with big winnings, you won't want to skip a chapter.

The good news is that you won't have to with the Diamond Tales: The Little Mermaid. The game is optimised for gameplay on Android, iOS, or Windows mobile devices.

Enjoy moving through the chapters and unlocking the fun features as you play this brand-new little mermaid theme slot at any Greentube-powered mobile gaming site.
