• What are Megaclusters™ Slots?

Megaclusters™ Slots are the brainchild of Big Time Gaming and they feature a new and thrilling pay mechanic that takes the Cluster Pays engine to a whole new dimension. BTG's beautifully engineered gaming mechanic Megaclusters™ is the pinnacle of excitement, and the next step in the evolution of their highly innovative Megaways™ gaming engine.

Our guide to Megaclusters™ Slots will give you all of the information that you need to understand how this gaming engine works, and we will also include a free play demo of each slot so that you can get into the thick of the action and try it out for yourself. The primary goal of this review page is to provide you with highly detailed Megaclusters™ reviews so that you can see which games you prefer to play in this new and exhilarating generation of online slots.

  • How do Megaclusters™ Slots work?

Before we get down to the nitty gritty of how the mechanic works let us first take you on a little refresher course of what an ordinary cluster pays slot is. You are likely to be familiar with recent games in this genre of slot such as Jammin Jars, where you have a set format of rows and reels but no paylines. You are paid a win when enough symbols are formed together in a cluster that are adjacent to each other, with these clusters being able to pay regardless of their position on the reels.

So the geniuses at BTG haven't added paylines to this mechanic, they have added Megaclusters™. This out of the box thinking now means that instead of playing cluster pays games on a set grid and format that never changes, the amount of symbols that can now appear in that grid can potentially change with each new spin of the reels.

We will use the first slot in the Megaclusters™ series to explain in more detail just how BTG have shook up the cluster pays mechanic and put their very own unique stamp on it. So as we know with Starclusters the game begins on a format of 4 reels and 4 rows, this is displayed in a Megaclusters™ value at the bottom of the reels which is 16, with each position on a reel being classed as a Megacluster ( 4 x 4 = 16 )

The magic of this gaming engine activates whenever a wins take place, each symbol that is part of a winning combination will explode and be replaced with 4 more symbols. These will then become Megaclusters™ in their own right which will also alter the Megaclusters™ meter beneath the reels, and in turn provide the player with even more chances to create winning combinations. 

The grid can begin to look somewhat spectacular as more of the symbols are split into 4, with each new explosion seeing the latest Megaclusters™ appear in the style of their own slot machine as they spin in reel formation. All consequent wins that are formed after this will see the winning clusters explode and be replaced with new symbols that will drop down to replace them, so in essence cascading reels

These cascading, or falling reels, behave in the same manner as we have seen in their Megaways™ counterpart, whereby they will continue until it is no longer possible for a winning cluster of symbols to be formed. Once this occurs the grid will then reset to its original format and a new spin will take place.

We know how important it is that you have a full understanding of how each Megacluster™ slot operates before you decide to play it for real money. This is why we have added a free play demo to every Megaclusters™ game that we review. Make sure to check back regularly as we update our catalogue as soon as a new release has gone live.

  • How do you trigger a bonus on a Megaclusters™ slot?

Currently the only way that we have seen the bonus round triggered on a Megaclusters™ slot is through a succession of consecutive reel cascades. As more slots are developed within this niche we anticipate that there will be more ways used to enter the bonus feature.

Possible new methods could include a progressive symbol collection as we have previously seen on other BTG games like Holy Diver, or maybe just a standard feature trigger through scatters landing in view. The one thing we do know however, is that whatever route is taken in the future with regard to feature triggers, it will be fun, exciting, and leading the way in terms of online slot innovation. 

  • What bonus features are there on a Megaclusters™ slot?

It's still very much early days for the Megaclusters™ mechanic but so far we have been treated to increasing multiplier wilds, as well as a free spin bonus round that increases the size of the grid you are playing on. 

Really the increased playing area for the bonus round is again another touch of genius from BTG. This will open up more possibilities as the engine develops and offer new options with regard to the features that can be included within each game. We could well be seeing colossal grids of symbols during free spin bonuses that are packed full of modifiers and enhancers. 


Cluster pays games have always had a strong following and in more modern times awesome games such as Dragonfall and Reactoonz have really helped this particular niche of slot grow. Big Time Gaming are always looking to take online slots to a new level, and with the introduction of Megaclusters™ this is exactly what they have done with cluster slots. 

The more that this new genre of slot grows, the more we can expect to see new concepts taking place within it. One of the things that we love the most about BTG is that they are never happy to sit and wallow in their success, they are constantly looking to drive their ideas forward and offer users of their slots the best experience there is online. 

We didn't think it that could ever get better than Megaways™, but our friends from down under have once again shown their prowess in slot development, with Megaclusters™ having the potential to blow away anything that has become before it.
