What Is Star Clusters Megaclusters™?

Star Clusters Megaclusters™ is an 8-reel, 4-row video slot developed by Big Time Gaming. The provider is known for revolutionising slot designs with the introduction of two game mechanics – Megaways™ and Megaclusters™.

Star Clusters Megaclusters™ Top Features

This title has a structure of 4-8 reels, but there are no Star Clusters Megaways™ or traditional paylines. Still, the old-school feel and the retro gem symbols will make you feel at home if you’re a fan of casino classics.

Cluster Pays

Because there are no paylines to bet on, in order to trigger a winning combination, you need 5 matching symbols horizontally or vertically on the reels.

The Star Clusters Megaclusters™ or Cluster Pays mechanic is simple to understand but highly profitable – when it gets triggered, every special symbol that is part of a winning combination gets split into 4 other smaller symbols. This creates more Megaclusters™, which in turn allows even more chances to score a payout.

In the base game, the maximum numbers of Megaclusters™ you can get is 64.


The mechanic above is doubled by another Big Time Gaming favourite – cascading reels or “reactions”. When the smaller symbols create winning combinations, they get blasted from the reels and replaced by new ones until no more winning combinations are formed.

The free spins round is triggered when you manage to get 5 or more consecutive “reactions” in the base game. During this round, the configuration of the slot expands to a 8×8 grid, meaning the maximum number of Megaclusters™ you can get increases to 256.

You will be awarded with 2 free spins and 1 extra for each win after the 5 mentioned above. If a 10x multiplier gets added to the Gold Wild symbol, you will receive another 2 free spins.

Multiplier Wilds

The game features two types of Wild symbols – a regular Wild and a special Gold Wild. Whilst they can both substitute for any regular symbol, the latter is more valuable and the one to pay special attention to.

That is because, if a Gold Wild is involved in a cluster, a multiplier that starts at 1x gets added. This multiplier increases by 1x for every other Gold Wild that you can trigger as part of a cluster, with no upper limit set for its value.

Every new spin will reset the multiplier, but this doesn’t apply to the free spins round.

Cascading Reels

Star Clusters Megaclusters™ uses the cascading reels mechanic. This is a well-known feature to Megaways slots fans, and can be found in many releases by Big Time Gaming. You can try it in Royal Mint, Bonanza and Monopoly Megaways™.

Here, the feature activates only when a first cluster is formed, causing four smaller symbols to appear in the grid. When these smaller symbols are involved in a winning combination, they will explode, and new symbols will fill the reels. This way you can cash in on additional wins, as the new symbols might create new winning combos. On top of that, if you get 5 or more consecutive reactions, you’ll trigger the free spins bonus round!

Star Clusters Megaclusters™ RTP, Volatility and Win Potential

Star Clusters Megaclusters™ has a medium/high variance level, which makes it more appealing than other Big Time Gaming slots with explosive volatility. The theoretical RTP is 96.54%. The maximum win you can get in the base game is 14,407x your stake and 23,960x your stake during the free spins round.

Star Clusters Megaclusters™ and Betting Range

You can try this title for as little as £0.20 per spin, a small investment that is affordable for any casual player, making it easier to purchase plenty of rounds. The maximum bet allowed is £20.

Theme, Slot Design & User Experience

Because the theme and visuals both take a backseat in this slot, neither are exceptionally polished or remarkable. Similar to its sister slot, Star Cluster Megapays™, everything is rather straightforward – the reels are set on a yellow backdrop on which dozens of multicoloured gems rest (turquoise, orange, green, etc.).

The main points of focus are the unique game engine and bonus features, which create a superior user experience and draw player attention.

Paytable and Special Symbols

  • Precious stones (yellow, green, blue, red, etc.) – These pay between 10x – 50x for a cluster of 25 symbols. The highest value symbol is the purple gemstone.
  • Wild symbols (Star Wild symbol + special Gold Wild)

Star Clusters Megaclusters™ Mobile Play

If you’re a fan of Starburst, Bonanza or Candy Crush, you’ll be pleased to know Star Clusters Megaclusters™ offers a similar experience and plays just as well on a mobile device. The developer used JS/HTML5 technology, thus the slot is compatible with all mobile operating systems (Android/iOS).

If you choose to play on the go on a smaller screen, we advise you to switch your device to landscape orientation. All functions, special features and visuals will remain intact.

How to Play Star Clusters Megaclusters™

As we mentioned previously, Star Clusters Megaclusters™ is very easy to play – all you have to do is set your desired bets and click the spin button. Your goal is to create winning combinations with 5 or more matching symbols of any size. They need to be adjacent to each other, horizontally or vertically.

With the exception of the UK, players from any other jurisdiction can customise their game session with two additional options – Autoplay (allows you to use up to 100 Autospins) and win/loss limits.

Star Clusters Megaclusters™ Pros & Cons


  • Gold Win Multiplier with no upper limit
  • Free spins
  • Big win potential
  • First slot to employ the Megaclusters™ mechanic


  • Theme is not very original
  • Graphics are outdated and generic

Star Clusters Megaclusters™ Slot Verdict

The Megaclusters™ mechanic is a star in Big Time Gaming’s portofolio, one that we can also identify in other popular titles like Cyberslot Megaclusters™.

This unique game engine is the primary focus of Star Clusters Megaclusters™ too. The theme is rather cliché, but the execution is still beautiful, with the assortment of multicoloured gemstones leaving a lasting visual impact.

Players will also be entertained by the special symbols splitting into smaller ones, as the repeated action creates a trance-like experience that keeps you spinning and coming for more, further enhanced by the energetic music in the background.
