About Star Clusters Megaclusters™

Star Clusters Megaclusters™ from Big Time Gaming is the first online video slot to feature the new Megaclusters™ gaming engine.  With this highly versatile new mechanic at the core of operations, winning symbols will be split into smaller symbols allowing the base game grid of 4 reels and 4 rows to expand to 64 symbols, whilst the free spin feature super grid of 8 reels and 8 rows can expand up to 256 symbols.


 The name of the slot is a bit of a giveaway as far as the theme is concerned, and whilst BTG may not have gone for a full battle star Galactica approach, there is certainly a cosmic feel to the game. In-game action is additionally pumped up through the aid of some new age electronic music, whilst a number of popular soundbites from tv, film and online influencers can be heard throughout

Star Clusters Paytable & Symbols

A fairly generic approach has been taken by Big Time Gaming with regard to the symbols that can be found throughout the slot. These all come in the form of coloured gems, with the lower paying section of the paytable represented by the turquoise gem, yellow gem, orange gem and green gem. The most powerful symbols on Starclusters are the blue gem, red gem and purple gem, that holds a value of 50x if 25 or more of them are clustered together in one win.

Star Clusters Wild Stars

Players should pay particular attention to the wild star symbols that feature heavily on Star Clusters. There are two versions of this star, with one of them being a very basic wild symbol, and the other more extravagant shining star acting as a wild multiplier. The special star also has a position above the reels where its current multiplier value can be seen.

The key to success throughout Star Clusters is the inclusion of the wild multiplier star in your clusters of wins. Each time that a wild multiplier star is part of a winning combination of symbols, the value of it will increase by x1, this can be improved upon further if you continue to create more wins with it from one initial spin.

Whilst several standard wilds can appear on the pay grid at any one time, there can only ever be 2 wild multiplier symbols present on the reels in both the base game and the bonus feature. Keep a look out for both of the wild multiplier stars being included in the same win, when this happens they will multiply each other first and then the win, which can lead to some big payouts.

Star Clusters Megaclusters™ base game

The base game will initially begin with you playing on a grid of 4×4 with 16 Megaclusters™ in play, which is highlighted at the bottom of the reels. Improving the size of the grid and bringing the Megaclusters™ mechanic into play, is your goal which in turn will create more chances for you to win.

This unique gaming engine kicks in when you connect 5 or more matching symbols adjacent to each other. When this takes place each individual symbol will explode and 4 smaller symbols will replace it by rolling in as if they were their own set of tiny reels. When the grid has been fully expanded in the base game, it can reach a total of 64 Megaclusters™.

Star Clusters Cascading Reels

BTG and Star Clusters utilise the cascading reels mechanic after the larger symbols have been replaced by the smaller ones. Every win that occurs that involves the smaller symbols will firstly see them eliminated from the grid, and then all other smaller symbols above them will drop down to replace them.

This is going to of course leave a space at the top, and this is where the cascading reels come into their own and deliver new symbols from above to fill the spaces.

As is often the case with cascading slots, you’re aiming to achieve as many cascades as possible in one series of spins. Not only does this rack up more wins and potentially increase the size of your wild star multiplier, it is also through this method that you trigger the free spin feature on Star Clusters Megaclusters™.

Star Clusters Free Spin Feature

So as we just touched upon, the bonus feature is triggered on Star Clusters when you compete a succession of 5 winning reactions or cascades. Completing these 5 wins will award you with 2 free spins to begin the bonus round, with each successful winning reaction thereafter adding an extra 1 spin to your total.

Something to keep an eye on whilst all this is happening is the value of your wild star multiplier at the top of the screen. Ideally you would like this to be as high as possible, as its value at the feature trigger will be carried over into the bonus round itself.

Immediately upon the feature entry you will notice that you playing on a much larger grid, which is in fact 8×8 in size and begins with a total of 64 Megaclsuters™ active.

Again the aim is to hit 5 or more matching symbols adjacently within the grid to initiate the Megaclusters mechanic. Once active you will again see the winning symbols explode and each be replaced with 4 smaller symbols.

The more wins you can create the more Megaclusters you can bring into play, with the maximum amount of 256 Megaclusters being available if you can clear all larger symbols from within the playfield.

Pivotal to releasing the full potential of the bonus round is the wild star multiplier. As with the base game each time that a wild star multiplier is present in a win, it will cause the value of it to increase by x1, with the key factor being that during the bonus round its value will not reset back to x1 when a spin comes to an end.

As you have a bigger grid to play on in the bonus round, the dream scenario is to hit a large amount of winning clusters that include both of the wild star multipliers. If for example you had a running total of a x12 multiplier and then both stars were a part of a winning combo, they would first multiply each other to equal 144x, and then that value would multiply the total of the winning combination of symbols.

You can be awarded with extra spins during this bonus round by continuing to increase the value of your multiplier. When you reach 10x and all multiples of that value therafter, you will receive an extra 2 free spins.

Star Clusters Megaclusters™ wrap up

New Gaming engines are always exciting, and Star Clusters is set to begin a new genre of slot that has all of the potential to be extremely popular and rival its Megaways™ counterpart.

There will however be mixed feelings about Star Clusters for certain, as some of the bonus features can be very low paying, but this is something that you have to accept when you are triggering free spin rounds more frequently than you would normally, especially on a BTG slot.

Overall though for a debut slot with a new mechanic, Star Clusters has set a high standard and given the developers a good idea of where to take this exciting niche of games next. We eagerly await what Big Time Gaming have to bring us in the future with Megaclusters™, and hope it’s as entertaining as this initial effort.
