Theme, Graphics, and Sound

There is no specific theme for this game, but it can be categorized as retro or vintage. It combines the traditional fruit machine appearance with some extra features and contemporary accents. As a result, it differs from all other games.

The smart graphics and some of the traditional symbols on fruit machines are given a modern 3D facelift.

There is an upbeat and fast-paced music as the background (with a little ’70s feel); and there’s a whoosh sound when it spins. It makes a popping sound whenever it flips/reveals, on the other hand, winning combination rings a bell.

Mystery Stacks RTP, Volatility, and Payout

On average, the Mystery Stacks video slot has a 95% RTP (though this may differ between casinos). It is highly volatile and has a maximum payout of 5000x the bet amount.

How to win at Mystery Stacks 

The game uses a 5×3 grid. It has ten pay lines. To form a winning combination, the player needs to land three or more of the same symbol on one line. Each payline can start anywhere on an area of five reels and three rows. As with almost all pokies, the highest paying combination per line is considered valid here.

• The lowest-paying symbol is the cherry. Landing three of these on a payline gives a payout of 1x the bet amount. 
• The order of the remaining symbols (low to high) is: lemon, orange, plum, watermelon. 
• The higher-paying symbols are the Bar symbols (single, double, and triple). 
• The Liberty Bell symbol is the highest-paying symbol, with three of them resulting in a win of 10x the bet stake and five resulting in a win of 50x the bet stake.
• Mystery Stacks does not feature a Scatter symbol or a Wild symbol.

Mystery Stacks bonus features 

In addition to the standard symbols mentioned earlier, there are some additional ones that definitely make the game more interesting. This is all part of the base game as there is no separate bonus game.

Mystery coin symbol

You can choose to enter the game where you will be spinning the reels. Sometimes when you do this one of the symbols might not appear as they are, but rather as a golden coin that has three question marks on it.

Having stopped spinning of all the reels, these coins will be flipped simultaneously to show the same sign. Doing so will ensure that more winning combinations are achieved through having multiple positions with the same symbol.

What makes it even better is that some of these perplexing coins will instead flip many times, say five. Each time the symbols are revealed, their values escalate and consequently the potential win also goes up. The payouts are made by the last flip.

Mega Coin

Mega Coin is shown at times, but not always. This comes in the form of a 3×3 coin and operates like the mystery coin by uncovering nine symbols of the same type. In contrast, there must always be some sort of reward that accompanies every occasion in which one lands on this icon.

Erratic Moves

The Mystery Stacks slot also features ‘erratic moves’ as an added bonus.  In some cases, the screen starts flashing randomly and the reels are shifted to enable wins. From time to time, a reel might be locked while other reels spin multiple times consecutively.

This also happens when the screen flickers on and off at random. Typically, a good win is coming up when lights come on and go off sporadically.

Mystery Stacks Review – Summary 

The Mystery Stacks by Silverback Gaming might just be the perfect choice for you if you are searching for a timeless game with updated graphics as well as imaginative ways to win. The RTP is 95%, there is no shortage of winning opportunities, and it could potentially pay out up to 5000 times.
