Mermaid's Treasure Trove Review

With wild multipliers swimming around and increasing their value with each stroke, do you really want to miss out on this opportunity to land big wins? Mermaid’s Treasure Trove promises some big win potential, but will the feature set leave the slot floundering?

Gameplay & Features

This cluster pays creation looks big and there's a good reason for that! This is a big game and smaller devices may not pick up all the details perfectly. What you have is seven reels and seven rows that make up a grid of 49 places. 

Upon each place lands a symbol that has some kind of connection with the watery underworld that may have been inspired by a certain Disney movie. The lowest paying symbols get you between 0.20x and 20x and the highest paying symbols pay between 0.75x and 150x. 

The idea is that at least five matching symbols create a winning combo by landing on the grid and that they must touch vertically or horizontally. You can have up to 49 matching symbols if you completely fill the grid. 

You've probably seen this before in grid slots where winning combinations will disappear and new symbols come down onto the screen. Some symbols can carry a random multiplier worth between 5x and 100x and these will help increase wins before they explode before your eyes.

Another symbol to watch out for is the wild multiplier and these can turn up as winning symbols are removed from the grid. They act as a wild and substitute for other regular payers and will increase their wild multiplier each time they take part in a win. It begins at 1x but after a win, the wild will move and the multiplier will increase. Two or more wilds can join together and create a big combo 

Bonus Game 

The free spins bonus is very much an extension of the base game and you'll need between three and seven scatter symbols to get there. On offer is a collection of free spins where you can play up to 18 times for free and any wild multipliers that were on the screen when you triggered the game will go through to the feature around with you. 

During the free spins bonus, multiplier wilds stick on the screen and will offer their multiplying powers throughout the bonus game. Extra scatter symbols will mean extra free spins as they land. 

You can increase your chances of landing scatter symbols by paying an extra 50% on top of your base bet and players outside the UK have two bonus buy options. The regular free spins game costs 100x and in return, you get a random number of free spins. If you pay 400x, you'll trigger the super free spins bonus with a random number of free spins but the multiplier wild starts at 10x instead of 1x. It's quite a large gamble if you decide to go for the latter.

Multiplier Wild Feature

Multiplier wilds appear if a win forms without a multiplier. It'll turn up randomly wherever it fancies and has a 1x multiplier to start with. Each time it's used in a combo, the multiplier increases and then moves to another place. Two or more wilds can create a wild combo and you can see multipliers landing as part of regular paying symbols, which are worth up to 100x.

Free Spins

Between 3 and 7 scatter symbols will trigger the free spins bonus and in return, you'll get your hands on between 10 and 18 free spins. During this bonus game, multiplier wilds will stay in view and move around until the end of the bonus game. Any wilds that are present during the triggering spin will go with you and stay throughout the feature. You can grab extra free spins as you play.

Win Potential

The base game has a huge number of symbols landing with each spin and they might apply multipliers as well. If this is the case, you'll see some large payouts and those wild multipliers can help them grow even further. However, the volatility is high and that means you could see a lot of spins that simply don't produce a win. When the big ones come along, you could make your way to a max win of 10,000x.

Design

As mentioned, this game may have taken some inspiration from a certain mermaid-themed Disney movie but I can't confirm it! All of the symbols hint in that direction and even the little abandoned building at the bottom of the ocean, where the game takes place, is quite reminiscent of Ariel's secret hideout. The soundtrack is a bit dodgy and the animations are quite rudimentary but I did like how the symbols explode when they take part in a win.

Our Verdict

Mermaid's Treasure Trove is, in many respects, quite a standard cluster pays slot but you won't find many games that offer portable wild multipliers! They add a little extra excitement to the journey and if they start growing, who knows where they might take your bankroll.
