Star Clusters Megaclusters Review

Last Update: 04.08.2021. Author: SlotCatalog.

Once again Big Time Gaming has revolutionized the industry with an epic new engine innovation. The Megaclusters™ engine is as big of a deal as the Megaways engine was when it first came, and it will most likely have the same impact. Star Clusters Megaclusters is a regular orgy of Reaction wins, as the symbols split into smaller versions of themselves and the cascading wins feature kicks in. This is a must try slot for sure, and we have to salute the BTG crew for not resting on their laurels.

The 4x4 grid is hurtling through a colorful wormhole at warp speed, and the screen is filled with sparkling jewels of different colors and sizes. The cluster pays engine has forever been altered with this game, as winning symbols will now split into 4 smaller versions of themselves. Not only that, but if you win with the smaller symbols, these are removed and replaced, just like the cascading wins feature that’s included in most Megaways engine titles.


The psytrance soundtrack is layered with sample tributes to Pac Man, Street Fighter and Bonanza, and you really want a good stereo or a decent set of headphones to get the most out of this game. The main attraction is the bonus round, where the grid size increases to 8x8 and you can get plenty of extra spins. The progressive gold star wild multiplier does not reset during the free spins, and it has no upper limit. This is a medium to high variance title, and wins up to a whopping 23,000x your stake is possible here.

What symbols are there?

All the symbols are different color gemstones in this game, kind of like the BTG game that started the whole Megaways frenzy, namely Bonanza. The purple gemstone is the highest payer, and it somewhat stands out from the rest in terms of value. There is also a rainbow star wild symbol and a gold rainbow wild symbol in play here. You need between 5 and 25+ symbols in a cluster to win, and here is the paytable for Star Clusters Megaclusters slot:

  • Purple gemstone - Pays 50x for 25+ in a cluster
  • Red gemstone - Pays 30x for 25+ in a cluster
  • Blue gemstone - Pays 25x for 25+ in a cluster
  • Green gemstone - Pays 20x for 25+ in a cluster
  • Orange gemstone - Pays 20x for 25+ in a cluster
  • Yellow gemstone - Pays 10x for 25+ in a cluster
  • Light blue gemstone - Pays 10x for 25+ in a cluster

What are the bonus features?

The big innovative feature in this game is the Megacluster engine. Whenever you land a winning cluster, all the involved symbols split into 4 smaller symbols. When you win with the smaller symbols, these are removed to make space for new symbols to fall into place. This process goes on as long as you keep landing new winning combos. The original 4x4 grid with 16 tiles can thus be expanded to a 8x8 grid with 64 tiles. This is how the Reactions feature works in Star Clusters Megaclusters.

With a rainbow color background, the golden star is the Wild Multiplier symbol in this game, and it starts with a 1x multiplier value. Whenever at least one Gold Multiplier Wild takes part in a winning combo, the feature is activated. The multiplier will increase by 1x for each time you win with a Gold Wild, but the multiplier will reset after the winning streak has finished in the base game. You can land up to 2 Gold Wilds on a single spin, and things change drastically in the bonus round we’ll get to next.

Free spins in Star Clusters Megaclusters

If you manage to get 5 Reactions in a row during the base game, you will trigger the Free Spins bonus round. This will give you 2 free spins, plus 1 extra spin for every Reaction you get above the minimum limit of 5. For example, if you have 7 cascading wins in a row, you will get 4 free spins to start with.

Whatever Gold Wild Multiplier you have built up in the base game will be carried over into the bonus round. The good news is that the progressive multiplier does not reset during the free spins feature, and you get 2 extra spins every time the multiplier increases by 10x. This means that you will get extra spins when you hit a 10x multiplier, and then 20x, 30x and so forth.


The grid is expanded to 8x8 in the bonus round, instead of the regular 4x4. This means that you can benefit from even more Megaclusters here, as the grid can now split into a 16x16 setup via the splitting of the winning symbols. Things will get quite interesting if you manage to take full advantage of this, as the 64 symbols can split into 256 symbols at the most.

How to play

Despite the somewhat complicated features, Star Clusters Megaclusters is quite easy to get started with. The first thing you can do is check out the paytable via the hamburger menu. This will give you an idea about how much each symbol is worth, and you’ll also find all the info you need about the game’s features and rules here.

You can also set up some autospins if you don’t want to play manually, and this is done via the “circular arrow” icon right next to the hamburger menu. You can choose between different amounts of autospins, and also decide if the autoplay feature shall stop when you have increased or decreased your bankroll a given amount. You can also stop the autoplay if you have won a single win above a given amount, or if you trigger the free spins bonus round.

Before you start playing, it’s time to choose your stake between 20p and £20, and now you are about ready to take this beauty for a spin. The Megaclusters mechanics is a thrill to watch, and you’ll probably fall into a pleasant trance watching the symbols split into smaller versions of themselves and be removed for ever-more winning chances.

The 200 Spins Star Clusters Megaclusters Experience

We were literally chomping at the bit to get going with this game, suckers for novelty and innovation as we are. Excitement was in the air as we set our bet level to £1, with 200 spins of pure joy to look forward to. We have not been this thrilled by a game since the first Megaways title, and we knew immediately that Big Time Gaming once again had made history with Star Clusters Megaclusters Experience slot.

The game is not really that complicated, but it will definitely dazzle you with the magnificent display of ever smaller gemstones. We found ourselves fascinated for a long time by the Megaclusters that kept forming, and we kept winning decent amounts in the base game. Nothing massive, but we won enough 1x to 10x wins to keep us afloat while we waited in anticipation to trigger the bonus round.

The gold star wild came to our rescue a few times, and our biggest base game win came after almost 150 spins. We had a beautiful 4 Reactions win, which landed us a 134x our stake and almost took us into the free spins feature. We had to wait a while more for that to happen though, but towards the end of the 200 spin test run we finally got lucky.


We landed a 6 Reactions win, which gave us 3 free spins and our 3x multiplier was carried over from the base game. The initial payout of 19x was summed up, and we pressed the start button to play out the bonus round. As we reached the 10x multiplier value we got 2 extra spins, and with all the cascading wins it feels like a lot more. In the end we pocketed a respectable 642x our stake, and we hope you are at least as lucky as we were with our first test run of this game.

Review Summary

Star Clusters Megaclusters slot is nothing short of a milestone in the casino world, and they really know how to think outside the box down-under at the BTG headquarters. We have these guys to thank for the Megaways engine, and now we are eternally in a debt of gratitude for their amazing Megaclusters engine.

This game has that “oddly satisfying” quality that just makes you want to play more and more, and it comes with a massive 23,000x max win potential. Granted, the most you can win in the base game is 1,300x your stake, but who cares, as the free spins feature is seamlessly introduced after 5 cascading wins in a row. Here the unlimited progressive multiplier can go berzerk, and we are pretty sure this game will be as strong an influence on other developers as Bonanza was when it first came.


  • Innovative Megaclusters™ engine
  • Progressive multiplier wild
  • Free spins with progressive wild multiplier
  • Medium to high volatility and 23,000x max win potential


  • Visuals are kind of generic

If you appreciate Star Clusters Megaclusters you should also try:

This is a game that it’s hard not to like, and it’s equally hard to find similar games since this is the first of its kind. Still, we will give it a go, and present you with some other slots that are somewhat similar to Star Clusters Megaclusters. At least they are similar when it comes to the theme, if not the gameplay and mechanics.

Starburst" - is at least visually similar to Star Clusters Megaclusters slot, and both games have the word “star” in their title. This is the most popular slot ever, and perhaps a megaclusters version would be a good idea (are you listening, NetEnt?). Of course, this is a lightweight when it comes to volatility and potential, not least compared to the beast Big Time Gaming has created.

Gemtastic - is filled with different colored gemstone symbols too, and it comes with a 6x5 grid and 30 ways to win. The volatility is high here, and you can win up to 10,000x your stake. You will benefit from 3x3 mega symbols, wilds, cascading wins and a respins feature. It’s a somewhat similar game in terms of visuals, and it’s well worth checking out.

Star Wilds Hot Spins - is another “star” titled slot you can check out. It comes with 4 sets of reels in the bonus round, which means you can win 4 times as much here. Four is really the lucky number, as winning at least 4x your stake will trigger the bonus round. This where you get to quadruple your winnings, and all wilds you land will be cloned to the same position on all 4 reels. This also increases the progressive win multiplier, and you’ll benefit from an RTP of 99.83 % during the Hot Spins feature. The max win is capped at £250,000, which is the same as most Megaways engine games.

Bonanza - is the breakthrough slot that made the Megaways engine a household item. Big Time Gaming has since licensed out their innovative mechanics to numerous other developers, but we thought this original game was worth mentioning in the same review as BTG’s next milestone innovation of a similar fashion. The main attraction is the free spins feature with unlimited progressive multiplier, and you can win up to 10,000x your stake.
